Design and Evaluation of a Smartphone Based Wearable Life-Logging and Social Interaction System

摘要

In this paper we outline the design, development and evaluation of a smartphone based life-logging and social interaction reminder system intended for use by persons with dementia. By using a smartphone, the wearer's daily activities can be recorded in picture format, along with meta data providing activity levels and location data. In addition to this data, social interactions can also be logged and subsequently identified, using Quick Response (QR) codes. The intervention was evaluated on six healthy participants aged between 24 - 46 years of age who wore the system for 2.5 hours. The qualitative feedback received was that the technology was easy to use and was responsive and accurate at identifying, recording and displaying social interaction data.
