Advances in technology enable us to store more information about our world, so much that many people suffer from information overload. Although we have the capacity to store a digital video record of a person's entire day using the QuickCam, such a record would take hours to review. StartleCam offers an alternative that selectively stores a series of images when the startle response is detected, indicating that these images are of possible interest to the wearer[LeD94]. In this system, the digital camera captures an image once every second and stores those images in a rotating buffer of five images. When the startle response is detected, this indicates that a startling event probably occurred in the last one to three seconds (due to the latency in the response as described in the last section). The startle trigger causes the entire buffer of images from the last five seconds to be downloaded. This can then both be transmitted via the wireless link back to a remote location or simply saved locally on the wearable's hard disk. Figure 8 show a series of images captures in the StartleCam buffer when the wearer reacted to an sudden question from a friend at a nearby workstation. The series shows the images captured as the wearer turned from her computer to look at her friend. This series of images might be considered more interesting than screen shots of the wearer's own terminal which are more or less identical. By storing only selected events at high resolution the StartleCam can help manage the wearer's information load.
