Study explored older adults’ privacy considerations for technology based monitoring applications in eldercare that use video systems. It specifically introduced alternative vision based tools to determine whether distorting or “anonymizing” captured images affect older adults’ privacy concerns and willingness to allow such an application to be installed in their residence. Participants were 10 residents of an independent retirement community, all of whom were over 65 years of age and all but 2 of whom were female. The residents participated in a series of scenarios, each involving a daily activity such as sitting in the living room and having a visitor, or preparing a snack. These sessions were video recorded using different image processing and extraction approaches, including the extraction of a silhouette of the resident moving around the environment. Follow-up in-depth interviews with participants were conducted after a demonstration of the captured images. Findings indicated that shape extraction can alleviate privacy concerns associated with the use of monitoring cameras. Participants expressed no privacy concerns with silhouette images and emphasized the importance of anonymity in the video sequences. They furthermore expressed the desire to control system operation by being able to turn a vision-based system off and on, and also determine who has access to the collected information.
