MobiGaze : Gaze Interface for Mobile Devices

Today, touch-screen-based handheld mobile devices are widely used; however, they are awkward to use with one hand. We propose MobiGaze, which is a user interface that uses one’s gaze to operate a handheld mobile device. By using MobiGaze, one can target the entire display area easily, even when the device is quite large. Moreover, MobiGaze can use both gaze and touch interactions. The combination of gaze and touch becomes a novel interaction paradigm. A gaze-and-touch interface effectively avoids the Midas-touch problem. The authors adopted a gaze-tracking method that uses a stereo camera to develop MobiGaze, because the user’s line of sight is detected in 3D. This allows the user to move the handheld mobile device freely. They constructed a prototype MobiGaze system, which consists of two cameras with IR-LEDs, a Windows-based notebook PC, and iPod touches. The authors evaluated the accuracy in a laboratory experiment and developed several applications for MobiGaze. DOI: 10.4018/978-1-4666-1628-8.ch004
