Technical Examples

A first aspect of the present invention includes various sensor controls for pointing and control devices. The sensor controls are much easier and require much less physical effort to operate than conventional controls. The sensor controls have built-in feedback-generating means that produce feedback to the user, similar to conventional controls such as micro switches. The built-in feedback-generating means have simpler structure, they are either commercially available or built with a few commonly available simple components, hence, they should be reliable, and inexpensive to produce. The sensor controls of the present invention with built-in feedback-generating means can be used directly in place of the corresponding conventional controls of pointing and control devices, with no or little impact on any other component. A second aspect of the present invention is a pointing and control device incorporating such sensor controls. The pointing and control device of the present invention allows a user to rest his or her hand and fingers on the housing of the device in a most relaxed and natural posture, and the sensor controls can be operated either by curling a finger (on-and-off controls) or by sliding a finger (motion controls). The present invention greatly improves the posture of the user's hand and significantly reduces the corresponding stress that is typical of the prior-art pointing and control devices.
