With advances in digital devices and web applications it has never been easier to capture and share information with other people. Lifelogging devices such as the SenseCam automatically capture thousands of images per day. Sharing images captured from such a device would provide family and friends with a glimpse of life from the wearer’s perspective. In this study we examined whether the practice of sharing lifelog images would impact the wearer’s lifelogging behaviour. Ten family pairs participated in this study; ten older adults paired with ten younger adults. Each family member was asked to wear a SenseCam over the period of two weeks. The participants were given a SenseCam and a touch screen computer to upload their images. On one of these weeks the participants were advised to capture images for their own personal use and on the other week they were asked to share their images with other people. The participants were asked to fill out a questionnaire at the end of each week relating to their experiences using the SenseCam and also their interactions with the lifelog images. Interactions using the SenseCam browser were also automatically recorded. We analyse the recorded data and user feedback with a focus on the older and younger participants’ frequency of data collection/image browsing and contrast between sharing and non-sharing weeks.
