They have developed a range of other features, including using the mobile phone’s accelerometer to detect if there is camera shake. Taking group shots, using face detection software, the camera can vibrate to signal the number of heads fully in the frame.
Brewster points out that these are features, ‘we test in the lab and then send out into the world for usability tests. For example, when taking group shots, we originally had an audio version. But when we gave it to people they mainly used that feature in clubs and bars, where it is so noisy they can’t hear the audio signals, they much preferred the tactile feedback.’
The group is working on adapting these features for video and have camera manufacturers interested in their work. With Brewster’s interface the camera gives instant feedback and better pictures at no extra cost.
