Senso Flex
Concerning the Senso Flex, a crucial aspect for OAs is its setup demands. Observations made by the investigators and the perceived level of difficulty reported by the OAs indicated that, on average, the older participants performed very well in setting up the system. However, it became evident that HPs significantly underestimated OAs’ ability to properly set up and operate the Senso Flex. Similarly, HPs expressed concerns about the risk of falls when OAs train independently using the Senso Flex—a concern not shared by most OAs themselves. Both discrepancies were previously observed in the first study (focus group study) of the COCARE project [Nevertheless, participants in Switzerland and Italy repeatedly reported sensitivity issues with the Senso Flex, resulting in incorrect step detection. In addition, participants from both groups at all sites criticized specific hardware and software issues, namely, missing handrails, problems with internet connection, and orientation difficulties on the mat because of insufficient visual or tactile demarcations of the fields. All these issues, along with technological malfunctions, likely had a substantial impact on the deduction of SUS scores. Consequently, in the further evolution of the COCARE system, resolving these software and hardware problems is crucial to enhance its usability and acceptance.
