    Social robots for older users: a possibility to support assessment and social interventions

    In the last decades, various researches in the field of robotics have created numerous opportunities for innovative support of the older population. The goal of this work was to review and highlight how social robots can help the daily life of older people, and be useful also as assessment tools. We will underline the aspects of usability and acceptability of robotic supports in the psychosocial work with older persons. The actual usability of the system influences the perception of the ease of use only when the user has no or low experience, while expert users’ perception is related to their attitude towards the robot. This finding should be more deeply analysed because it may have a strong influence on the design of future interfaces for elderly-robot interaction. Robots can play an important role to tackle the societal challenge of the growing older population. The authors report some recent studies with older users, where it was demonstrated that the acceptability of robotics during daily life activities, and also in cognitive evaluation, could be supported by social robot

    Designing User Interfaces for the Elderly: A Systematic Literature Review

    This paper discusses the issues of implied trust in ethical hacking. Ethical hackers are considered to be professionals and experts in their field. It is well documented that there is an implied trust toward professionals who are entrusted to undertake a task. Like many similar professions, such as ICT and computer forensics, there is no uniform or mandated code of ethics that an ethical hacker must adhere to. Given the nature of hacking and the potential for misuse and access to sensitive and confidential information, the need to ensure professionalism is maintained through ensuring competence and ethical behaviour is critical

    Intuitive learnability of touch gestures for technology-naïve older adults

    Touch-based interactions, if intuitive and natural, should be highly learnable. However, the learnability of touch gestures as a computer interaction modality cannot be taken for granted and should be evaluated empirically. This is especially true when technology-naïve older adults are concerned, given the psychological and physical constraints associated with this age range. To investigate this issue, we conducted a study with 17 technology-naïve older adults, whose experience with technology was mostly limited to making calls with mobile phones. Specifically, the participants were presented with three simple digital games on an interactive tabletop surface and asked to play the games on their own with minimal instruction or help. The first two games required the use of a drag gesture whereas the third game required the use of a rotate gesture. The main research question was whether the older adults could learn the gestures effectively and efficiently. A set of variables such as task duration and gesture accuracy were measured. Results showed that the learnability of a drag gesture was relatively high and that the participants could transfer this skill across the games. In contrast, the learnability of a rotate gesture was low and most of the participants failed to demonstrate any improvement over the tasks of the game. These findings partially corroborate those of earlier work. Implications for future work are drawn, especially exploring the potential of social interactions between older adults for enhancing the learning effects

    Metric for Designing Inclusive User Interfaces: Action Research on the Implementation of the Care Act 2014

    Get PDF
    This action research is aimed at creating metric for inclusive user interfaces that provide are intuitive and mimic the natural conversation to bridge the skill gap between skilled users and novice users. This metric will help user interface designer to measure the ‘inclusivity’ of their design, thus producing services that as easy as an IKEA manual. This action research is conducted in Nottinghamshire County Council who invested resources to create online channel that enables customers to apply online for social care services, while recognising that their customer base is very diverse. The council adopted an inclusive design strategy to cater to all users with different needs and computer literacy levels

    User experience of mixed reality applications for healthy ageing : A systematic review

    Get PDF
    Mixed reality (MR) technologies are being used increasingly to support healthy ageing, but past reviews have concentrated on the efficacy of the technology. This systematic review provides a synthesis of recent experimental studies on the instrumental, emotional and non-instrumental aspects of user experience of healthy older adults in relation to MR-related applications. The review was listed on PROSPERO, utilised a modified PICOS framework, and canvassed all published work between January 2010 to July 2021 that appeared in major databases (Scopus, PubMed, CINAHL, Web of Science, and the Cochrane Library). The literature search revealed 15 eligible studies. Results indicated that all included studies measured the instrumental quality of their applications, all but two studies measured the emotional reactions triggered by gameplay, and only six studies examined participants’ perception of non-instrumental quality of the applications. All included studies focused on improving a health domain such as cognitive or physical training. This suggests that the instrumental quality of the MR applications remains the focus of user experience studies, with far fewer studies examining the non-instrumental quality of the applications. Implications for game design and future research are discussed

    Investigating older adults’ preferences for functions within a human-machine interface designed for fully autonomous vehicles

    © Springer International Publishing AG, part of Springer Nature 2018. Compared to traditional cars, where the driver has most of their attention allocated on the road and on driving tasks, in fully autonomous vehicles it is likely that the user would not need to intervene with driving related functions meaning that there will be little need for HMIs to have features and functionality relating to these factors. However, there will be an opportunity for a range of other interactions with the user. As such, designers and researchers need to have an understanding of what is actually needed or expected and how to balance the type of functionality they make available. Also, in HMI design, the design principles need to be considered in relation to a range of user characteristics, such as age, and sensory, cognitive and physical ability and other impairments. In this study, we proposed an HMI specially designed for connected autonomous vehicles with a focus on older adults. We examined older adults’ preferences of CAV HMI functions, and, the degree to which individual differences (e.g., personality, attitude towards computers, trust in technology, cognitive functioning) correlate with preferences for these functions. Thirty-one participants (M age = 67.52, SD = 7.29), took part in the study. They had to interact with the HMI and rate its functions based on the importance and likelihood of using them. Results suggest that participants prefer adaptive HMIs, with journey planner capabilities. As expected, as it is a CAV HMI, the Information and Entertainment functions are also preferred. Individual differences have limited relationship with HMI preferences
