  • Patent number: 8633893
    Abstract: A solid-state roller on a pointing device with enhanced features. The solid-state design described herein allows the sensor to be placed on any shape of surface, such as one that has curvature in two directions. In one embodiment, a trench or downward curve contains sensors for detecting finger movement. The user's finger can thus bend about a knuckle in a curved motion to activate the sensor, requiring little or no movement of the finger up and down. The solid-state sensors can be of one of a number of designs. In one embodiment, multiple electrodes are contacted by a finger as it moves. Each electrode is coupled to a capacitive detection circuit, for detecting the change in capacitance as the electrode is contacted by the finger.

  • Publication number: 20070018970
    Abstract: An optical feedback mechanism corresponding to a variation in input by a user's digit on an input element. The variation in input can be movement by the user's finger, or a change in the amount of pressure or force applied to a button. In one embodiment, the optical feedback is a linear light array adjacent a solid-state scroll/zoom sensor, with the light corresponding to the finger position. Alternately, a solid state button could provide feedback corresponding to the amount of pressure in the form of a change in intensity, color or blinking. In one embodiment, the input signal from an input element alternates between a scroll, zoom and/or other functions depending on the current application.

  • Patent number: 6937225
    Abstract: The method and system serve to notify the user of an event through a control device. Active notification takes place even when the computer sound and screen are disabled, for example, when in a power saving mode or screen saving mode. Notification may include visual notification, audio notification, vibratory notification, or tactile notification. Tactile notification can also serve to provide a private notification system which will not alert or disturb other people in the vicinity of the user. Such tactile notification can be provided by means of a texture change in the surface of the control device. One way in which this could be done is by raising a plurality of pegs through the surface of a control device to change its texture.
