Method and System for Improving Keying Accuracy for Typing on Mechanical Keyboards of Small Computing Devices

Disclosed is a method and system for improving keying accuracy on mechanical keyboards of small computing devices. Small computing devices include devices such as, but not limited to, smart phones, personal digital assistants and Netbooks. Often the keys are very small and in close proximity to each other, making it difficult to depress the desired key. The disclosed method detects a user's finger movements and predicts which key the user is about to strike on a mechanical keyboard. Thereafter, the access to the key is made easier by elevating the key.

When the user prepares to depress a key, the key is made to protrude from the keyboard. This reduces the chances of the user depressing a wrong key or keys. In a scenario, one or more sensors are used to detect the key or the set of keys the user intends to use. For example, one or more of temperature sensors and/or photographic image sensors are used to detect finger movement when poised above a specific key on the keyboard.

In a scenario, the finger movement is detected using a temperature sensor, which detects a change in temperature as the finger gets closer to the key. Another way to detect the finger movement is to use a photographic image sensor, which recognizes a shadow on the key or uses image recognition technique to identify whether a finger is in proximity to a key on the keyboard.

In a scenar...
