Problems solved by technology

While their keypads are somewhat “storable”, the problem with that type of terminal is that the operator has a difficult time in hitting the proper key to efficiently do the job.
Current laptop and palmtop devices suffer from the problem of short stroke and compacted dense key layout.
Further difficulties arise when cursor movement is desired.
Accuracy, however, may be lacking with such data entry devices, inasmuch as the exact location of a particular cursor / data entry point may be difficult to discern.
This does not facilitate cursor movement while the operator's hands are on the alpha / numeric keys themselves.

Embodiment Construction

[0024]One embodiment of the present invention relates to an expandable signal generator apparatus 58, as shown in a partial side-elevational view, in FIG. 1, wherein an expandable key 60 has a pre-molded upper layer 62 in a desired key configuration, having an enclosed volume of open or closed cell foam 64. The upper layer 62 of the key 60, being made from a thin layer of plastic material which flexes when pressed by an outside force. The foam 64 is yieldable when pressed, yet has sufficient stiffness to maintain the fullness of the key in the absence of pressure thereon. A lower layer of thin, flexible plastic material 66 of about 10-20 mil thick PVC, or the like, may be disposed across the bottom of the key 60, as shown in FIG. 1. The key may be one of a plurality of such keys on a signal generator 70, which may be, in one embodiment, arrangable on the face of a force pad 68, which pad 68 utilizes “pressure” to generate a signal therewithin, as is shown in a side-elevational view,...

Abstract

Various embodiments of the present invention comprise a signal generator for sending an electrical signal from an expandable, flexible layer of material, the signal generator comprising an upper layer of flexible, resilient material and a lower layer of flexible, resilient material which between them define a cavity for enclosing an expandable material such as a cellular foam or gas, whereupon localized distortion of one of the layers of flexible material, effects a signal generation within the structure, which is transmissible through a proper circuit to an outside electrical device. A circuit may be arranged adjacent a plurality of said keys which senses when several of said keys are depressed in a skewed or sideways manner, so as to effect movement of a cursor or pointer on a monitor in communication with a processing unit and said keyboard.
