Background Memory issues especially are one of the main challenges for older adults in respect to maintaining independent living. Many older adults suffer from memory issues closely associated with prospective memory (PM), a form of memory that involves remembering to do something at the appropriate time in the future. To solve this issue, this research explores the designing of a product that enables the elderly to sustain independent living by supporting their prospective memory. Methods The research methodology, consisting of both the user study and design methods, was adapted from human-centered design (ISO 13407, 1999). The main user studies were a focus group and a participatory user design with seven elderly participants who live in London, UK. The design and development stages involved various design methods, including product design specification and prototyping. At the user evaluation phase, the user group using physical and digital prototypes evaluated the proposed design solution. Result Based on consecutive user studies of the focus group and user participatory design, a Smart Memory Supportive System (SMSS), which is a combination of interactive devices employing radio frequency identification (RFID) technology, was produced to support the prospective memory of the elderly. Within the design development phase, a couple of prototypes were created for evaluating the usability of the system by the user group. As a result, improvement points for usability were suggested, based on the user evaluation findings. Conclusions The proposed design system would benefit the elderly by satisfying their aspiration of maintaining independence by improving their safety and security. It would encourage them to organize a routine or semi-routine task without intrusiveness in their familiar home environment.
