The iCLIPS project is researching into technologies to facilitate more effective browsing and searching of multimodal digital lifelogs. To date we have captured 18 months of lifelog data for 3 main subjects with 1 month augmented with biometric data. Using this biometric data, in this study we investigate the utility of observed galvanic skin response (GSR), heart rate (HR) and skin temperature (ST) at time of item capture to indicate future importance of SenseCam events within lifelogs.
