3D user interface combining gaze and hand gestures for large-scale display

In this paper, we present a novel attentive and immersive user interface based on gaze and hand gestures for interactive large-scale displays. The combination of gaze and hand gestures provide more interesting and immersive ways to manipulate 3D information.

Mobile LCD device with transparent infrared image sensor panel for touch and hover sensing

In this paper, we propose a novel mobile LCD device for simultaneous touch and hover sensing. A transparent infrared image sensor panel allows the device to display contents and to detect touch and hover actions alternately. The proposed system has an advantage over touch screen devices in that a user interacts with a mobile device by not only touching the display screen but also hovering over the display screen.

45.2: Distinguished Paper: Novel LCD Display with a Sensible Backlight

In this paper, we describe a novel multi-touch LCD display architecture with hover sensing capability based on infrared sensor array. The proposed display architecture has an advantage over existing multi-touch LCD displays in that it maintains a slim form-factor of LCD displays without loss of a display quality while it is possible to sense multiple touches and hovers simultaneously.

Novel LCDs with IR-sensitive backlights

— In this paper, a novel multi-touch LCD architecture with hover-sensing capability is described. To detect multiple touch points and hover points simultaneously, a sensitive backlight, which is a backlight integrated with an IR sensor array, is introduced. The sensitive backlight uses visible light to display contents on a display screen and is also used to detect reflected IR light from objects on or near the display screen. The captured image from the sensitive backlight is used to extract touch and hover information. The proposed display architecture maintains the slim form factor of an LCD with no loss of display quality, while making it possible to sense multiple touches and hovers simultaneously.
