ResType: Invisible and Adaptive Tablet Keyboard Leveraging Resting Fingers

Text entry on tablet touchscreens is a basic need nowadays. Tablet keyboards require visual attention for users to locate keys, thus not supporting efficient touch typing. They also take up a large proportion of screen space, which affects the access to information. To solve these problems, we propose ResType, an adap…

Bridging the Generational Gap: Exploring How Virtual Reality Supports Remote Communication Between Grandparents and Grandchildren

When living apart, grandparents and grandchildren often use audio-visual communication approaches to stay connected. However, these approaches seldom provide sufficient companionship and intimacy due to a lack of co-presence and spatial interaction, which can be fulfilled by immersive virtual reality (VR). To understa…

TypeBoard: Identifying Unintentional Touch on Pressure-Sensitive Touchscreen Keyboards

Text input is essential in tablet computer interaction. However, tablet software keyboards face the problem of misrecognizing unintentional touch, which affects efficiency and usability. In this paper, we proposed TypeBoard, a pressure-sensitive touchscreen keyboard that prevents unintentional touches. The TypeBoard a…

HandSee: Enabling Full Hand Interaction on Smartphone with Front Camera-based Stereo Vision

We present HandSee, a novel sensing technique that can capture the state and movement of the user's hands touching or gripping a smartphone. We place a right angle prism mirror on the front camera to achieve a stereo vision of the scene above the touchscreen surface. We develop a pipeline to extract the depth image of…

Accurate and Low-Latency Sensing of Touch Contact on Any Surface with Finger-Worn IMU Sensor

Head-mounted Mixed Reality (MR) systems enable touch interaction on any physical surface. However, optical methods (i.e., with cameras on the headset) have difficulty in determining the touch contact accurately. We show that a finger ring with Inertial Measurement Unit (IMU) can substantially improve the accuracy of c…
