Elderly Healthcare Monitoring Using an Avatar-Based 3D Virtual Environment

Abstract

Homecare systems for elderly people are becoming increasingly important due to both economic reasons as well as patients’ preferences. Sensor-based surveillance technologies are an expected future trend, but research so far has devoted little attention to the User Interface (UI) design of such systems and the user-centric design approach. In this paper, we explore the possibilities of an avatar-based 3D visualization system, which exploits wearable sensors and human activity simulations. We present a technical prototype and the evaluation of alternative concept designs for UIs based on a 3D virtual world. The evaluation was conducted with homecare providers through focus groups and an online survey. Our results show firstly that systems taking advantage of 3D virtual world visualization techniques have potential especially due to the privacy preserving and simplified information presentation style, and secondly that simple representations and glancability should be emphasized in the design. The identified key use cases highlight that avatar-based 3D presentations can be helpful if they provide an overview as well as details on demand.

Wearable technologies in osteoarthritis: a qualitative study of clinicians’ preferences

“…This was also the case for conditions other than OA. 18 19 Participants agreed that technology could add a limited value to the diagnostic process but its value could be proved in long-term management, offering monitoring and objective measures of patients’ status, if implemented appropriately. Adoption of technology in current practice was related, in the first instance, to its ease of use and its effectiveness in providing easy to interpret and timely data to clinicians.…”

Comparison of two workflows for Web-based 3D smart home visualizations

“…3D user interfaces (3DUIs) have been seen beneficial in landscape and built environment visualization [6], [7], and the maturity of current WebGL technology already allows the development of webbased commercial applications in this domain [8]. In the context of individual buildings, 3DUIs have been utilized, for example for visualizing patient activities for caretakers [9], [10]. In comparison to traditional UIs however, 3DUIs provide additional challenges for designers [11].…”

Older Adults Designing Avatars for Socializing

“…Studies including older adults in this area have been mainly concerned in the healthcare or monitoring characteristic of an avatar representation e.g. [7]. Yet, not many studies have considered older adults' use of avatars in social contexts nor older adults as designers of their avatar self-representations.…”
