GazeBar: Exploiting the Midas Touch in Gaze Interaction
Carlos Elmadjian, Carlos H. Morimoto
Abstract
Imagine an application that requires constant configuration changes, such as modifying the brush type in a drawing application. Typically, options are hierarchically organized in menu bars that the user must navigate, sometimes through several levels, to select the desired mode. An alternative to reduce hand motion is the use of multimodal techniques such as gaze-touch, that combines gaze pointing with mechanical selection. In this paper, we introduce GazeBar, a novel multimodal gaze interaction technique that uses gaze paths as a combined pointing and selection mechanism. The idea behind GazeBar is to maximize the interaction flow by reducing ”safety” mechanisms (such as clicking) under certain circumstances. We present GazeBar’s design and demonstrate it using a digital drawing application prototype. Advantages and disadvantages of GazeBar are discussed based on a user performance model.
