“…The system consists of three devices: a bathroom scale for monitoring weight and balance, a Grip-ball for monitoring grip strength, and a mobile phone with a built-in accelerometer for monitoring physical activity 13–16. The devices are equipped with Bluetooth so that the information can be transferred automatically to the mobile phone.…”

PurposeTo involve elderly people during the development of a mobile interface of a monitoring system that provides feedback to them regarding changes in physical functioning and to test the system in a pilot study.Methods and participantsThe iterative user-centered development process consisted of the following phases: (1) selection of user representatives; (2) analysis of users and their context; (3) identification of user requirements; (4) development of the interface; and (5) evaluation of the interface in the lab. Subsequently, the monitoring and feedback system was tested in a pilot study by five patients who were recruited via a geriatric outpatient clinic. Participants used a bathroom scale to monitor weight and balance, and a mobile phone to monitor physical activity on a daily basis for six weeks. Personalized feedback was provided via the interface of the mobile phone. Usability was evaluated on a scale from 1 to 7 using a modified version of the Post-Study System Usability Questionnaire (PSSUQ); higher scores indicated better usability. Interviews were conducted to gain insight into the experiences of the participants with the system.ResultsThe developed interface uses colors, emoticons, and written and/or spoken text messages to provide daily feedback regarding (changes in) weight, balance, and physical activity. The participants rated the usability of the monitoring and feedback system with a mean score of 5.2 (standard deviation 0.90) on the modified PSSUQ. The interviews revealed that most participants liked using the system and appreciated that it signaled changes in their physical functioning. However, usability was negatively influenced by a few technical errors.ConclusionInvolvement of elderly users during the development process resulted in an interface with good usability. However, the technical functioning of the monitoring system needs to be optimized before it can be used to support elderly people in their self-management.

“…This multisensory analysis enables the lifestyle of the user to be defined, and thus enable abnormal situations to be detected and risks to be anticipated [3,4]. The work of this theme also attempts to include technical developments of new medical devices arising from the significant take-off of practices in health ambulatory support (eHealth) [5,6]. The axis of the embedded instrumentation focuses on the development of ambulatory microsystems and integration of new sensors to collect relevant information on the health status of the individual [7].…”

“…The key issue is the possibility of detecting those at most risk of falling in order to be able to perform a targeted intervention [4]. Innovative technologies can play an important role in remote monitoring and early identification of elderly people who suffer from functional decline [5]. Thus, an adapted prevention or rehabilitation program could be put in place, with progress followed over time [6].…”

Ambient Assisted Living (AAL) technologies can play an important role in helping elderly people achieve healthy ageing and maintain their autonomy. The balance quality tester (BQT) is a device for remote assessment of balance quality for older people at risk of falling. It has been validated both from a technical and a clinical perspective. However, for the BQT to be considered as a useful tool for long-term home monitoring of people with balance impairments, two issues are at stake: ease-of-use on a regular basis and trust in the validity of the data acquisition. To ensure this utility, a usage study has been made to understand the needs and values of different stakeholders: elders at risk of falling and their entourage, as well as health professionals. One main insight was the need to redesign the BQT, so as to fit the needs concerning ease-ofuse and trust in validity of data acquisition. Using a Human-centred and Participatory Design approach, the redesigning work relates to hardware design, interaction design, interface design, and most of all to standardizing the protocol of stepping-on the BQT. This paper describes the results, i.e. the design recommendations, and discusses the collaborative and iterative design process, which allowed the successful redesign of the BQT.
