Abstract:
A method for entering input data into an electronic apparatus, comprising the steps of(a) providing, for each one of a plurality of keying fingers, a corresponding pair of keyswitches, said fingers and said pairs corresponding one to one, each one of said keyswitches comprising a key part and a momentary-contact, two-state switch part, (b) positioning, for each one of said fingers, an inner keyswitch member of the corresponding keyswitch pair on the palm side of the middle phalanx part of said one finger, such that said inner keyswitch can be activated by pressing said side of the middle phalanx part of said one finger against the key part of said inner keyswitch with sufficient, predetermined force, (c) positioning, for each one of said fingers, an outer keyswitch member of the corresponding keyswitch pair on the palm side of the distal phalanx part of said one finger such that said outer keyswitch can be activated by pressing said side of the distal phalanx part of said one finger against the key part of said outer keyswitch with sufficient, predetermined force, (d) providing means to support the switch parts of said keyswitches in said positions such that said switch parts are not substantially displaced by forces applied by the keying fingers, (e) entering a chord by contemporaneously activating a set of said keyswitches so as to define an ordered combination of activated and non-activated keyswitches, (f) providing means to convert ordered combinations of activated and non-activated keyswitches to input data, (g) providing means to transmit said input data to said apparatus, said apparatus including means to receive and process said input data, (h) repeating step (e) until all desired input data have been entered.
