Abstract
Abstract There is provided an improved structure for teaching the formation of intelligence characters. A planar card is provided including a visible representation of a character formed of at least one stroke element and a plurality of individually inclined finger slides projecting out of the plane of the card for encouraging movement of the finger in a desired direction along the stroke path of the element.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
79 words
A device for teaching the formation of intelligence characters comprising: a. a planar card including a visible representation of a character formed of at least one stroke element, and b. a plurality of individual inclined plane finger slides having a major portion of the surface thereof projecting above the plane of said card and lying along a predetermined stroke in forming said character and configured to encourage movement of the finger in a desired direction along said stroke element.
Claim 2
Independent Claim
79 words
A device for teaching the formation of intelligence characters comprising: a. a planar card including a visible representation of a character formed of at least one stroke element, and b. a plurality of individual inclined plane finger slides having a major portion of the surface thereof projecting above the plane of said card and lying along a predetermined stroke in forming said character and configured to encourage movement of the finger in a desired direction along said stroke element.
Claim 3
Independent Claim
79 words
A device for teaching the formation of intelligence characters comprising: a. a planar card including a visible representation of a character formed of at least one stroke element, and b. a plurality of individual inclined plane finger slides having a major portion of the surface thereof projecting above the plane of said card and lying along a predetermined stroke in forming said character and configured to encourage movement of the finger in a desired direction along said stroke element.
Claim 4
Independent Claim
79 words
A device for teaching the formation of intelligence characters comprising: a. a planar card including a visible representation of a character formed of at least one stroke element, and b. a plurality of individual inclined plane finger slides having a major portion of the surface thereof projecting above the plane of said card and lying along a predetermined stroke in forming said character and configured to encourage movement of the finger in a desired direction along said stroke element.
Claim 5
Dependent Claim
39 words
A device in accordance with claim 1 which is further characterized by means projecting above the plane of the card at the desired beginning of a stroke for guiding the finger in the proper direction toward said finger slides.
Claim 6
Dependent Claim
25 words
A device in accordance with claim 1 which is further characterized by stop means for resisting finger movement at the end of a stroke element.
Claim 7
Dependent Claim
27 words
A device in accordance with claim 1 wherein at least a portion of a stroke element includes finger slides which are easily retraced in the opposite direction.
Claim 8
Dependent Claim
13 words
A device in accordance with claim 1 wherein the finger slides are unidirectional.
Claim 9
Dependent Claim
23 words
A device in accordance with claim 1 wherein the finger slides include a relatively long inclined plane portion and an abrupt cliff portion.
Claim 10
Dependent Claim
