SMART TOUCHPAD INPUT DEVICE

摘要

The subject technology discloses a system for filtering out touches on a touch sensitive input device (e.g., touchpad) during a typing-intensive task. A typing task detection module receives key-press events and computes the typing speed in terms of keys per second in combination with a determined amount of typing based on a number of received key-press events. When input speed and amount of continued typing are higher than a threshold, the typing task detection module then determines that the user is performing a typing task. The typing mode and other characteristics of user's typing activity are used to adjust the responsiveness of touchpad. The subject technology further includes a touchpad responsiveness adjustment module. This module receives the determined typing speed and amount of typing from the typing task detection module, and adjusts the input sensitivity (which controls the responsiveness) of the touchpad to filter out accidental finger touches.

1. A method comprising:
receiving a plurality of key-press events; determining if a typing-intensive task is performed based on a typing speed derived from the received plurality of key-press events; and adjusting an input sensitivity of the touch-sensitive component for a time interval based on a keypress interval derived from the typing speed when the typing-intensive task is determined to be performed.
