摘要
Image processing techniques that can improve the user interface experience associated with key-based input devices. In one embodiment, a motion sensitive mechanical keyboard can utilize orthogonally-oriented cameras to sense hand/finger motion over the surface of the keys. This arrangement can enable a standard look and feel mechanical keyboard to receive command and cursor input (e.g., pointing and gestures) from the user without requiring the user to move the user's hand off the keyboard. The image processing techniques can be utilized to minimize or remove undesirable cursor movement that can occur based on certain detected hand/finger motion from such cameras, including looming and/or vertical motions for example.
