Abstract

Graphical User Interfaces (GUIs) are widely used and pointing devices are required to operate most of them. We have proposed Xangle, a pointing method using two accelerometers for wearable computing environments. The cursor is positioned at the intersection of two straight lines, which are synchronized with the angles of the accelerometers at fingers. However, Xangle is difficult to be used in daily-life, when the user frequently changes which part of the body they point with. Therefore, we propose a method of changing the body parts used for pointing according to the situation. Additionally, we proposed a method to accelerate the pointer and a method to layout menu items for Xangle since these methods are suitable for using GUI in wearable computing environments. We confirmed that the proposed method was effective from the results of evaluations.
