Abstract
Abstract A system and method of displaying handwriting parameters in which a dynamic parameter, such as the tangential speed, of a stylus moving across a surface is determined, a trace of the stylus across the surface is recorded on a record member, and the dynamic parameter is represented on the record member to provide a means of visually observing both the handwriting itself and one or more dynamic parameters of the handwriting process.

Claims Analysis
Total Claims: 36
Claim 1
Independent Claim
101 words
A method of displaying handwriting and handwriting parameters from movement of a stylus across a surface, comprising: resolving the tangential speed of the stylus tip as it moves along a trace across the surface; recording on a record member the stylus trace as a thin line; and recording an envelope, which is visually distinguishable from the thin line, on the record member along and about the thin line, in which the width of the envelope is modulated in proportion to the stylus tangential speed to visually indicate the stylus tangential speed, for displaying both the handwriting and the stylus tangential speed.
Claim 2
Independent Claim
101 words
A method of displaying handwriting and handwriting parameters from movement of a stylus across a surface, comprising: resolving the tangential speed of the stylus tip as it moves along a trace across the surface; recording on a record member the stylus trace as a thin line; and recording an envelope, which is visually distinguishable from the thin line, on the record member along and about the thin line, in which the width of the envelope is modulated in proportion to the stylus tangential speed to visually indicate the stylus tangential speed, for displaying both the handwriting and the stylus tangential speed.
Claim 3
Dependent Claim
13 words
The method of claim 1 in which the record member includes a printer.
Claim 4
Dependent Claim
16 words
The method of claim 1 further including determining the pressure of the stylus on the surface.
Claim 5
Dependent Claim
34 words
The method of claim 3 further including recording on the record member, along the thin line, a representation of the pressure of the stylus tip as it moves along the trace across the surface.
Claim 6
Dependent Claim
21 words
The method of claim 4 in which recording the representation of the pressure includes assigning display colors to represent pressure values.
Claim 7
Dependent Claim
19 words
The method of claim 4 in which recording the pressure includes assigning display gray shades to represent pressure values.
Claim 8
Dependent Claim
23 words
The method of claim 1 further including determining the location and duration of pauses of the stylus as it moves across the surface.
Claim 9
Dependent Claim
14 words
The method of claim 7 further including recording the pauses on the record member.
Claim 10
Dependent Claim
23 words
The method of claim 8 in which recording the pauses on the record member includes displaying a symmetric pattern around the pause locations.
Claim 11
Dependent Claim
23 words
The method of claim 9 in which displaying a symmetric pattern includes representing the pause duration with the size of the symmetric pattern.
Claim 12
Dependent Claim
13 words
The method of claim 9 in which the symmetric pattern is a circle.
Claim 13
Dependent Claim
17 words
The method of claim 1 further including determining the motion of the stylus just above the surface.
Claim 14
Dependent Claim
21 words
The method of claim 12 further including recording on the record member the motion of the stylus just above the surface.
Claim 15
Dependent Claim
18 words
The method of claim 1 further including determining the tilt of the stylus in relation to the surface.
Claim 16
Dependent Claim
18 words
The method of claim 1 further including outlining the envelope to indicate stylus direction in overlapping envelope areas.
Claim 17
Dependent Claim
86 words
The method of claim 1 further including recording on the record member as a second thin line a previous stylus trace, and a second envelope which is visually distinguishable from the second thin line along and about the second thin line, in which the width of the second envelope has been modulated in proportion to the stylus tip tangential speed along the previous stylus trace to visually indicate the previous stylus trace and the stylus tip tangential speed, to allow visual comparison of two handwriting samples.
Claim 18
Dependent Claim
15 words
The method of claim 1 in which the record member includes a video display device.
Claim 19
Independent Claim
100 words
