Input Device Including a Scroll Wheel Assembly for Manipulating an Image in Multiple Directions
摘要:
A scroll wheel assembly includes a rotatable member. Encoded rotation of the rotating member causes scrolling of an image on a display screen along an axis. An actuator is located within the rotational member. Pressure on different parts of the actuator causes scrolling of the image in opposing directions along a second axis. Pressure upon additional parts of the actuator can provide additional screen functions. Functions and commands caused by manipulation of the rotatable member or actuator may also be programmable.
