Tracking down a solution: exploring the acceptability and value of wearable GPS devices for older persons, individuals with a disability and their support persons

Perceived Benefit and Satisfaction With a Tablet Computer and an Emergency Smartwatch by Older Adults and Their Relatives: Prospective Real-World Pilot Study

Background

Assistive technologies (ATs) have the potential to promote the quality of life and independent living of older adults and, further, to relieve the burden of formal and informal caregivers and relatives. Technological developments over the last decades have led to a boost of available ATs. However, evidence on the benefits and satisfaction with ATs in real-world applications remains scarce.

Objective

This prospective, real-world, pilot study tested the perceived benefit and satisfaction with different ATs in the real-world environment.

Methods

Community-dwelling adults aged ≥65 and their relatives tested a tablet computer with a simplified interface or a smartwatch with programmable emergency contacts for 8 weeks in their everyday life. Perceived benefits and satisfaction with ATs were assessed by all older adults and their relatives using different assessment tools before and after the intervention. Outcome measures included the Technology Usage Inventory, Quebec User Evaluation of Satisfaction with Assistive Technology 2.0, and Canadian Occupational Performance Measure.

Results

A total of 17 older adults (tablet computer: n=8, 47% and smartwatch: n=9, 53%) and 16 relatives (tablet computer: n=7, 44% and smartwatch: n=9, 56%) were included in the study. The number of participants that were frail (according to the Clinical Frailty Scale) and received care was higher in the smartwatch group than in the tablet computer group. Older adults of the smartwatch group reported higher technology acceptance (Technology Usage Inventory) and satisfaction (Quebec User Evaluation of Satisfaction with Assistive Technology 2.0) scores than those of the tablet computer group, although the differences were not significant (all P>.05). In the tablet computer group, relatives had significantly higher ratings on the item intention to use than older adults (t12.3=3.3, P=.006). Identified everyday issues with the Canadian Occupational Performance Measure included contact/communication and entertainment/information for the tablet computer, safety and getting help in emergency situations for the smartwatch, and the usability of the AT for both devices. While the performance (t8=3.5, P=.008) and satisfaction (t8=3.2, P=.01) in these domains significantly improved in the smartwatch group, changes in the tablet computer group were inconsistent (all P>.05).

Conclusions

This study highlights the remaining obstacles for the widespread and effective application of ATs in the everyday life of older adults and their relatives. While the results do not provide evidence for a positive effect regarding communication deficits, perceived benefits could be shown for the area of safety. Future research and technical developments need to consider not only the preferences, problems, and goals of older adults but also their relatives and caregivers to improve the acceptability and effectiveness of ATs.

Informing existing technology acceptance models: a qualitative study with older persons and caregivers

New technologies can help older persons age in place and support their caregivers. However, they need to be accepted by the end-users to do so. Technology acceptance models, such as TAM and UTAUT and their extensions, use factors like performance expectancy and effort expectancy to explain acceptance. Furthermore, they are based on quantitative methods. Our qualitative study investigates factors fostering and hindering acceptance among older persons and their caregivers for a variety of assistive technologies, including wearables, ambient sensors at home with and without cameras and social companion robots. The goal of this paper is twofold: On the one hand, it investigates the factors of technology acceptance models in a qualitative setting. On the other hand, it informs these models with aspects currently overlooked by them. The results reveal that performance expectancy and effort expectancy are relevant for acceptance. We also find that reliability, anxiety around technology and different social aspects have an influence on acceptance of assistive technology in aged care for all end-user groups. Our findings can be used to update current technology acceptance models and provide in-depth knowledge about the currently used factors.

An Integrative Review of the Feasibility and Effects of the Use of Location-Tracking Devices by Persons Living With Cognitive Impairment

OBJECTIVES

This study aimed to examine the effects of location-tracking devices on persons living with cognitive impairment, investigate facilitators of and barriers to using the devices, and provide future directions for the use of the devices.

METHODS

An integrative review was conducted using 5 databases: PubMed, Embase, Web of Science, CINAHL, and Scopus. From the 1429 initially identified studies, 10 were included in the review.

RESULTS

Location-tracking devices benefited persons living with cognitive impairment and their informal caregivers. The devices brought more independence to persons living with cognitive impairment, allowing them to go outside and feel safer there. Furthermore, the devices reduced the caregivers' worries about their loved ones being lost.

CONCLUSIONS

Location-tracking devices have the potential to increase independence in persons living with cognitive impairment and to decrease psychological stress in informal caregivers. In the future, ways to minimize the barriers to using location-tracking devices need to be determined.

Use of technology to sustain mobility in older people with cognitive impairment and dementia: a scoping review

PURPOSE

This paper provides a review of studies that evaluated technology devices to sustain various forms of mobility in older people with cognitive impairment or dementia and mobility problems (e.g., inability to ambulate or difficulties to orient with consequent failures to reach relevant destinations).

METHODS

A literature search was performed for English language articles indexed in PubMed, PsycINFO, and Web of Science. This search was then supplemented with an ancestral and forward search. The search covered the period ranging between January 2010 and October 2020.

RESULTS

Twenty-seven articles were included in the review. They were divided into four groups according to whether they aimed to promote (a) supported ambulation, (b) use of safe power wheelchair, (c) ambulation guided by orientation cues, and (d) ambulation with GPS-based assistance. The studies were coded in terms of the objective pursued, technology used, participants involved, strategies applied to assess the technology, and outcome reported.

CONCLUSION

A variety of technology devices are available to address the mobility problems of older people with cognitive impairment or dementia. The devices' accessibility and usability differ widely. Data on their impact are still largely preliminary and new systematic research is needed.IMPLICATIONS FOR REHABILITATIONA variety of mobility problems may afflict older people with cognitive impairment or dementia and curtail their opportunities to freely move indoor or outdoor.Technology devices have been developed to (a) promote forms of supported ambulation, (b) facilitate safe use of power wheelchairs, (c) deliver orientation/navigation cues, and (d) ensure tracking and possible assistance.The technology devices differ in terms of accessibility and affordability, with some of them readily available and others at a developmental stage.Data on the effectiveness of the various technology devices in reducing the impact of the mobility problems are still largely preliminary and new systematic research is needed.

Methods to assess the effectiveness and acceptance of information and communication technology-based assistive technology for older adults: a scoping review

An aging society is a growing challenge for families, social and rehabilitation service providers, and economies. Information and communication technology-based assistive technology can bolster the independence of older adults (65 years and above) and reduce their burden on caregivers. Currently, there is no unified methodology to assess the effectiveness and acceptance of these technologies. The present study undertakes a scoping review to (1) identify and characterize the methods for assessing the acceptability and usability of information and communication technology-based assistive technologies, (2) explore the advantages and disadvantages of the assessment methods, (3) determine the possibilities of combining the assessment methods and (4) define the most commonly used assessment method and set of outcome measures. The literature was searched in MEDLINE, Scopus, IEEE Cochrane and Web of Science bibliographic databases using the keywords defined by reviewers for articles in English published between 2011 and 2021. Of the 1696 matches, 31 met the inclusion criteria. It was found that a combination of different assessment methods was common in outcome measurements. Of the 31 studies, assessment methods were combined in 21 studies and multiple questionnaires were used in 11 studies. The most common technique of outcome measurement was the use of questionnaires (81%), conducting interviews (48%) and recording usability-performance measures (39%). The advantages and disadvantages of the assessment methods could not be determined in the selected studies in this scoping review.

Benefits of a Wearable Activity Tracker with Safety Features for Older Adults: An Intervention Study

Accidental falls and physical inactivity are important age-related issues for which smart technologies have demonstrated potential utility. This research aimed to explore the benefits of combining wearable activity monitors and telecare for older adults. A four-month interventional study was conducted between June 2021 and February 2022 in Slovenia. A purposive sample of 22 dyads of older adults aged 60 years and over and their relatives or family members used a wearable GoLiveClip device. The Pillar Integration Process was used to analyze the quantitative and qualitative data. Seven pillars emerged: (1) the use of smart technologies as a motivator for physical activity; (2) factors related to smart technology use affecting physical activity levels; (3) increased usefulness of smart technologies for users who completed the study; (4) activity monitoring as the most useful functionality of the solution; (5) the influence of technical problems on usefulness; (6) the influence of age and previous experience with smart technologies on usefulness; and (7) moderate psychological effects of smart technology use. Activity trackers were found to effectively promote physical activity in older adults, and safety features were shown to be an important part of the solution, regardless of health status or physical activity level.

Factors influencing informal carers' acceptance of assistive telecare systems in the pre- and post-implementation phase: A scoping study

Assistive telecare systems (ATSs) have great potential to be beneficial for informal carers (ICs) providing long-term care to older people (OP). However, little is known about ATS acceptance among ICs. This scoping study aims to investigate various factors that influence the ICs' acceptance of ATSs over time in the pre- and post-implementation phases. A five-stage scoping study was conducted. A systematic search of five bibliographic databases (Science Direct, Scopus, CINAHL, PubMED and Proquest Social Sciences Database) was conducted in September 2020, supplemented by a round of grey literature searches. Using the established selection criteria, 37 publications published between 2000 and September 2020 were included. The data were analysed with Atlas.ti 8 using content-based analysis and a combination of deductive and inductive approaches. The results show that work on understanding acceptance of ATS only gained wider attention after 2010. Seven key factors of ATS acceptance were identified: benefits and concerns about ATS, care situation, the influence of the OP, carer characteristics, perceived need to use and social influence. Several subfactors were also found. The post-intervention acceptance factors were found to be more nuanced than the pre-implementation factors, indicating that first-hand experience with ATSs enabled study participants to provide a more tangible, extensive and in-depth overview of the various ATS acceptance factors. This scoping review is useful for ATS developers, providers, health and social care scholars and practitioners, policy makers and commissioners, all of whom seek to improve and facilitate the provision of long-term care in the community.

Does Being Ill Improve Acceptance of Medical Technology?-A Patient Survey with the Technology Usage Inventory

Acceptance of new medical technology may be influenced by social conditions and an individual’s background and particular situation. We studied this acceptance by hypothesizing that current and former COVID-19 patients would be more likely to accept an electrocardiogram (ECG) “patch” (attached to the chest) that allows continuous monitoring of the heart than individuals who did not have the disease and thus the respective experience. Currently infected COVID-19 patients, individuals who had recovered from COVID-19, and a control group were recruited online through Facebook (and Instagram) and through general practitioners (GPs). Demographic information and questions tailored to the problem were collected via an online questionnaire. An online survey was chosen in part because of the pandemic conditions, and Facebook was chosen because of the widespread discussions of health topics on that platform. The results confirmed the central hypothesis that people who had experienced a disease are more willing to accept new medical technologies and showed that curiosity about new technologies and willingness to use them were significantly higher in the two groups currently or previously affected by COVID-19, whereas fears of being “monitored” (in the sense of surveillance) were significantly higher among people who had not experienced the disease and threat. Experiencing a serious disease (“patient experience”) promotes acceptance of new medical technologies.

Overcoming barriers to the adoption of locating technologies in dementia care: a multi-stakeholder focus group study

Background

Locating technologies are a subtype of assistive technology that aim to support persons with dementia by helping manage spatial orientation impairments and provide aid to care partners by intervening when necessary. Although a variety of locating devices are commercially available, their adoption has remained low in the past years. Several studies have explored barriers to the adoption of assistive technologies from the perspective of professional stakeholders, but in-depth explorations for locating technologies are sparse. Additionally, the inputs of business professionals are lacking. The aim of this study was to expand knowledge on barriers to the adoption of locating technologies from a multi-stakeholder professional perspective, and to explore strategies to optimize adoption.

Methods

In total, 22 professionals working in business (n = 7), healthcare (n = 6) and research (n = 9) fields related to gerontology and gerontechnology participated in our focus group study. Perceptions on the value of using locating technologies for dementia care, barriers to their adoption, as well as salient services and information dissemination strategies were explored. After verbatim transcription, transcripts were analysed following an inductive data-driven content analysis approach in MAXQDA.

Results

Six key adoption barriers centering on: (1) awareness-, (2) technological-, (3) product characteristic- and (4) capital investment-based limitations, (5) unclear benefits, as well as (6) ethical concerns emerged. The interplay between barriers was high. Five core themes on services and information dissemination strategies centering on: (1) digital autonomy support, (2) emergency support, (3) information dissemination actors, (4) product acquisition, and (5) product advertising were extracted.

Conclusions

Our study with interdisciplinary stakeholders expands knowledge on barriers to the adoption of locating technologies for dementia care, and reinforces recommendations that an interdisciplinary strategy is needed to optimize adoption. Also, our findings show that focusing on services to increase digital autonomy and on information dissemination strategies has been largely overlooked and may be particularly effective.

Fidelity and utility of GPS loggers as a tool for understanding community participation of older adults

OBJECTIVE

The purpose of this research was to examine the fidelity and utility of global positioning system (GPS) technology for studying community mobility indicators, and to explore implications for community participation for older adults.

METHOD

A longitudinal cohort design with community-dwelling older adults (n = 33) was employed. GPS spatial data and activity logs were collected at baseline and one year later. Data were analysed to evaluate the fidelity of the GPS protocol, the nature and frequency of destinations, and the stability of community mobility over time.

RESULTS

Findings include evidence for high reliability of the GPS loggers to record out-of-home trips when compared to activity logs; utility of the technology for identifying frequency and type of occupational destinations; and the relative stability of two community mobility variables over time. GPS loggers generate key insights into how older adults move in and through their community as they engage in a range of occupations.

CONCLUSION

GPS technology is a robust and useful tool for gathering novel information, especially when combined with qualitative data. GPS loggers may be incorporated in evaluation or to tailor interventions. Community mobility enables social participation, and warrants further research using these methods to support processes of aging in place.

Acceptance, adoption, and usability of information and communication technologies for people living with dementia and their care partners: a systematic review

PURPOSE

This review aims to examine the instruments, approaches, scales, or assessment tools used to evaluate technology acceptance, technology adoption, and usability of information and communication technologies (ICTs) for people living with dementia and their care partners.

METHODS

A systematic literature review was conducted. Studies that explored the use of instruments, approaches, scales, or assessment tools to evaluate the technology acceptance and usability of ICTs for people living with dementia and their care partners were identified through five databases: Medline, EMBASE, CINAHL, Web of Science, and Scopus.

RESULTS

We included 74 out of 2182 papers. The most common scales used included the System Usability Scale (SUS) (11%), the ISONORM 9241/10 Questionnaire (4%), and the Post-Study System Usability Questionnaire (PSSUQ) (4%). Most (59%) of the included approaches, however, were bespoke (i.e., created by the authors for a particular study) and were not named. The approaches or tools used to assess technology acceptance, technology adoption, and usability of ICTs that applied to people living with dementia had an average of 15 items and used an average of 5.23 scale points.

CONCLUSION

There is no clear, standardised approach for assessing the technology acceptance, technology adoption, and usability of ICTs for people living with dementia and their care partners. The findings of this review may be used by academics to design and implement improved and more consistent assessment tools to assess technology acceptance, technology adoption, and usability of ICTs for people living with dementia and their care partners.IMPLICATIONS FOR REHABILITATIONThe number of ICTs for people with dementia and their care partners that can be used for rehabilitation is increasingThe most commonly recognized assessment tools used in this study were the SUS, ISONORM 9241/10, and PSSUQ questionnaires.For the custom assessment tools, the average number of items included in this study was 15 with five-point bidirectional labelling.There is no clear, standardized approach for assessing the technology acceptance, technology adoption, or usability of ICTs for people with dementia and their care partners.

Wearable Health Devices in Health Care: Narrative Systematic Review

BACKGROUND

With the rise of mobile medicine, the development of new technologies such as smart sensing, and the popularization of personalized health concepts, the field of smart wearable devices has developed rapidly in recent years. Among them, medical wearable devices have become one of the most promising fields. These intelligent devices not only assist people in pursuing a healthier lifestyle but also provide a constant stream of health care data for disease diagnosis and treatment by actively recording physiological parameters and tracking metabolic status. Therefore, wearable medical devices have the potential to become a mainstay of the future mobile medical market.

OBJECTIVE

Although previous reviews have discussed consumer trends in wearable electronics and the application of wearable technology in recreational and sporting activities, data on broad clinical usefulness are lacking. We aimed to review the current application of wearable devices in health care while highlighting shortcomings for further research. In addition to daily health and safety monitoring, the focus of our work was mainly on the use of wearable devices in clinical practice.

METHODS

We conducted a narrative review of the use of wearable devices in health care settings by searching papers in PubMed, EMBASE, Scopus, and the Cochrane Library published since October 2015. Potentially relevant papers were then compared to determine their relevance and reviewed independently for inclusion.

RESULTS

A total of 82 relevant papers drawn from 960 papers on the subject of wearable devices in health care settings were qualitatively analyzed, and the information was synthesized. Our review shows that the wearable medical devices developed so far have been designed for use on all parts of the human body, including the head, limbs, and torso. These devices can be classified into 4 application areas: (1) health and safety monitoring, (2) chronic disease management, (3) disease diagnosis and treatment, and (4) rehabilitation. However, the wearable medical device industry currently faces several important limitations that prevent further use of wearable technology in medical practice, such as difficulties in achieving user-friendly solutions, security and privacy concerns, the lack of industry standards, and various technical bottlenecks.

CONCLUSIONS

We predict that with the development of science and technology and the popularization of personalized health concepts, wearable devices will play a greater role in the field of health care and become better integrated into people's daily lives. However, more research is needed to explore further applications of wearable devices in the medical field. We hope that this review can provide a useful reference for the development of wearable medical devices.

Comparing the Usability and Acceptability of Wearable Sensors Among Older Irish Adults in a Real-World Context: Observational Study

BACKGROUND

Wearable devices are valuable assessment tools for patient outcomes in contexts such as clinical trials. To be successfully deployed, however, participants must be willing to wear them. Another concern is that usability studies are rarely published, often fail to test devices beyond 24 hours, and need to be repeated frequently to ensure that contemporary devices are assessed.

OBJECTIVE

This study aimed to compare multiple wearable sensors in a real-world context to establish their usability within an older adult (>50 years) population.

METHODS

Eight older adults wore seven devices for a minimum of 1 week each: Actigraph GT9x, Actibelt, Actiwatch, Biovotion, Hexoskin, Mc10 Biostamp_RC, and Wavelet. Usability was established through mixed methods using semistructured interviews and three questionnaires, namely, the Intrinsic Motivation Inventory (IMI), the System Usability Scale (SUS), and an acceptability questionnaire. Quantitative data were reported descriptively and qualitative data were analyzed using deductive content analysis. Data were then integrated using triangulation.

RESULTS

Results demonstrated that no device was considered optimal as all scored below average in the SUS (median, IQR; min-max=57.5, 12.5; 47.5-63.8). Hexoskin was the lowest scored device based on the IMI (3.6; 3.4-4.5), while Biovotion, Actibelt, and Mc10 Biostamp_RC achieved the highest median results on the acceptability questionnaire (3.6 on a 6-point Likert scale). Qualitatively, participants were willing to accept less comfort, less device discretion, and high charging burdens if the devices were perceived as useful, namely through the provision of feedback for the user. Participants agreed that the purpose of use is a key enabler for long-term compliance. These views were particularly noted by those not currently wearing an activity-tracking device. Participants believed that wrist-worn sensors were the most versatile and easy to use, and therefore, the most suitable for long-term use. In particular, Actiwatch and Wavelet stood out for their comfort. The convergence of quantitative and qualitative data was demonstrated in the study.

CONCLUSIONS

Based on the results, the following context-specific recommendations can be made: (1) researchers should consider their device selection in relation to both individual and environmental factors, and not simply the primary outcome of the research study; (2) if researchers do not wish their participants to have access to feedback from the devices, then a simple, wrist-worn device that acts as a watch is preferable; (3) if feedback is allowed, then it should be made available to help participants remain engaged; this is likely to apply only to people without cognitive impairments; (4) battery life of 1 week should be considered as a necessary feature to enhance data capture; (5) researchers should consider providing additional information about the purpose of devices to participants to support their continued use.

User experience and clinical effectiveness with two wearable global positioning system devices in home dementia care

INTRODUCTION

The user experience and clinical effectiveness with wearable global positioning system (GPS) devices for persons with dementia (PwDs) and caregivers (CGs) remain unclear although many are available.

METHODS

Using a crossover design, 20 dyads tested two similar commercial GPS watches (products A and B) at home for 4 weeks each. Usability, product functions, design features and product satisfaction at home and the clinic were investigated. Caregiver burden and quality of life assessed clinical effectiveness.

RESULTS

The final 17 dyads rated the usability, telephone function, overall design features, font, buttons, and battery life of B significantly better than A. PwDs rated the overall design features and buttons of A significantly better than CGs. Product satisfaction with both products was significantly lower at home. Clinical effectiveness was not found.

DISCUSSION

User experience can be improved by optimizing specific product details. This might translate to clinical effectiveness. Social desirability bias may explain different product satisfaction ratings.

Usability Evaluation for the Amulet Wearable Device in Rural Older Adults with Obesity

Mobile health (mHealth) interventions hold the promise of augmenting existing health promotion interventions. Older adults present unique challenges in advancing new models of health promotion using technology including sensory limitations and less experience with mHealth, underscoring the need for specialized usability testing. We use an open-source mHealth device as a case example for its integration in a newly designed health services intervention. We performed a convergent, parallel mixed-methods study including semi-structured interviews, focus groups, and questionnaires, using purposive sampling of 29 older adults, 4 community leaders and 7 clinicians in a rural setting We transcribed the data, developed codes informed by thematic analysis using inductive and deductive methods, and assessed the quantitative data using descriptive statistics. Our results suggest the importance of end-users in user-centered design of mHealth devices and that aesthetics are critically important. The prototype could potentially be feasibly integrated within health behavior interventions. Centralized dashboards were desired by all participants and ecological momentary assessment could be an important part of monitoring. Concerns of mHealth, including the prototype device, include the device's accuracy, its intrusiveness in daily life and privacy. Formative evaluations are critically important prior to deploying large-scale interventions.

Real Time Monitoring of Children, and Adults with Mental Disabilities Using a Low-Cost Non-Invasive Electronic Device

There are a growing number of small children-as well as adults-with mental disabilities (including elderly citizens with Alzheimer's disease or other forms of age-related dementia) that are getting lost in rural and urban areas for various reasons. Establishing their location within the first 72 h is crucial because lost people are exposed to all kinds of adverse conditions and in the case of the elderly, this is further aggravated if prescribed medication is needed. Herein we describe a non-invasive, low-cost electronic device that operates constantly, keeping track of time, the geographical location and the identification of the subject using it. The prototype was made using commercial low-cost electronic components. This electronic device shows high connectivity in open and closed areas and identifies the geographical location of a lost subject. We freely provide the software and technical diagrams of the prototypes.
