Claim 1
Independent Claim
264 words
Simulated keyboard system for teaching keyboarding to students comprising: (a) a mat having an upper surface, and a bottom surface (b) a representation of keys arranged in a standard keyboard pattern on said upper surface in which the keys are permanently identified, said keys and pattern being substantially the same size as that of a standard keyboard for enabling the student to position his or her fingers in a traditional keyboarding posture, including a plurality of lines for dividing the keys of said keyboard into appropriate standard finger grouping columns for assisting the student in maintaining his or her fingers in the appropriate grouping columns while practicing keyboarding technique on said simulated keyboard, (c) a representation of a pair of human hands on said bottom surface, (d) each finger of each hand identifies indicia on said bottom surface which identifies with the appropriate keys of the finger group for the finger, (e) a wall chart which depicts a second simulated keyboard in which the individual keys of the keyboard are permanently identified and which has lines which divide the keys into appropriate finger grouping columns for enabling the student to view said second keyboard while manipulating his or her fingers on said first simulated keyboard in keyboarding exercises, and (f) an instruction book of keyboarding exercises which contains illustrations of a third simulated keyboard which is depicted in the same manner as said first and second keyboards for enabling the student to view the third keyboard while manipulating his or her fingers on said first keyboard while following the keyboarding exercises in the book.
