A multi-level pressure-sensing two-handed interface with finger-mounted pressure sensors

ABSTRACT

This paper proposes separating a pressure sensor off from an input device and attaching it directly onto a user's finger to allow the user to input pressure values into a computer with various devices and various places. This proposal solves the problem of requiring an individual pressure sensor for each pressure-sensing input device because we've attached a sensor to not a device which is pushed but rather a finger which pushes it. As an instance, we developed a multi-level pressure-sensing two-handed user interface by measuring the positions and pressure values of both the user's hands. The user can manipulate a screen object with the dominant hand and assist it by adjusting the position and the intensity of pressure of the dominant hand and non-dominant hand. We developed some GUI functions: cursor aura for expanding the sphere of its influence, non-dominant hand cursor for picking up a hidden window, and pressure-sensing keyboard input to add arousal to text. The advantages of our system are; (1) a user can use a favorite device and add pressure value, and (2) a user can enter a multi-level value by pressing heavily or lightly without looking at user's hands.
