Human-Centered Design Study: Enhancing the Usability of a Mobile Phone App in an Integrated Falls Risk Detection System for Use by Older Adult Users

Abstract Older adults are at greater risk of death and serious injury in transportation crashes which have been increasing in older adult cohorts relative to younger cohorts. Can technology provide a safer road environment? Even if technology can mitigate crash risk, is it acceptable to older road users? We outline the results from several studies that tested 1) whether advanced driver assistance systems (ADAS) can improve older adult driving performance, 2) older adults’ acceptance of ADAS and Autonomous Vehicle (AV) systems, and 3) perceptions of value for ADAS systems, particularly for blind-spot detection systems. We found that collision avoidance warning systems improved older adult simulator driving performance, but not lane departure warning systems. In a young to middle-aged sample the factor “concern with AV” showed age effects with older drivers less favorable. Older drivers, however, valued an active blind spot detection system more than younger drivers.

Adolescent Reproductive Health

BACKGROUND Adolescent pregnancies and sexually-transmitted infections continue to impact 15 – 19-year-olds across the globe. The lack of sexual reproductive health information in resource-limited settings can often be due to cultural and societal attitudes to adolescent sexual reproductive health. Innovative approaches, including mobile phone technologies, are needed to address the need for adolescent reproductive health information. OBJECTIVE To design and develop a mobile app prototype to provide confidential adolescent reproductive health information on demand and evaluate its usability and user experience. METHODS A human-centered design methodology was applied. This practice framework allowed the perspectives and feedback of adolescent users to be included in the iterative design process. Field usability testing enabled the adolescents to provide feedback on the functionality, usability, and usefulness of the app. RESULTS During the usability test, 62 (54.9%) of the adolescents that were followed-up had used the app at least once, 30 (48.4%) of these were male participants and 32 (51.6%) female. The app was described as ‘very interesting’ to use by 44 (70.9%) participants, 20 male and 24 female. The content was deemed to be either ‘perfectly’ or ‘well targeted’ on sexual reproductive health by 60 (96.7%) adolescents, and the app was rated ‘best app’ by 45 (72.6%) adolescents, 27 female and 18 male, with a p-value = 0.011. CONCLUSIONS A mobile phone app is a feasible and acceptable way to deliver adolescent sexual reproductive health information in resource-limited settings. The USSD mobile phone technology could deliver confidential information on demand.

Liquid Metal Ink

Pervasive detection of blood glucose is rather critical for the real-time disease diagnosis which would provide valuable guidance for treatment planning. Here, we established a health care platform for this purpose through incorporating the glucose detection with liquid metal printed sensor and the smart phone monitoring system together. The liquid metal ink composed of bismuth indium stannic (BIS) alloy was identified as an appropriate sensor material to be quickly written or printed on polyvinyl chloride (PVC) substrate at around 59 °C to form desired electrodes. It thus eliminated the complicated procedures as usually required in conventional sensor fabrication strategies. The alloy electrodes were characterized via cyclic voltammetry to demonstrate their practical functionality. Further, unlike using the commonly adopted glucometer, a smart phone was developed as the data acquisition and display center to help improve the portability and ubiquitous virtue of the detection system. Glucose solution in different concentrations was assayed via this platform. It was shown that there is a good linear relationship between the concentration and the integral value of the curve recorded by the mobile phone, which confirms the feasibility of the present method. This quantitative point-of-care system has pervasive feature and is expected to be very useful for future low-cost electrochemical detection.

Checking Behavior

Phubbing refers to the nonverbal behavior of glancing at, or using, one’s mobile phone during a face-to-face (FtF) interaction, whereby the mobile-phone-checking behavior is perceived to breach expectations of attention or etiquette. In general, phubbing can negatively affect interpersonal relationships and well-being. When younger family members’ phubbing behavior is perceived by older adult relatives as a violation of their conversational expectations, these older adults may feel ignored and disrespected. This study may be the first to investigate the associations between intergenerational family phubbing expectancy violations and indicators of well-being among older adults. Survey data were derived from a sample of U.S. Internet users aged 65 or above ( n = 679). The results suggested that both perceived frequency of family phubbing and family phubbing expectancy violations were inversely associated with mattering and indicators of well-being. Study limitations and potential directions for future research are discussed.
