The methodology includes audio-haptic feedback to present the spatial image information non-visually using an audible signal that varies as a function of the distance of the finger/stylus from the regions of a display that express the image features. ## Claims ### Claim 1 A method for improving a subject's spatial cognition and spatial memory, including: presenting spatial image information to the person through a non-visual medium; non-visual exploration and memorization of the spatial image to enhance the subject's understanding of the nature and relationships of components of the spatial image information to promote augmentation of the subject's spatial image memory; the subject thereafter drawing an image representation of the spatial image information; detecting and encoding errors in the image representation relative to the original spatial image; providing interactive feedback to the subject based on the subject's image representation, and wherein the step of presenting spatial image information includes providing an electronic touch-screen to display said spatial image information, the subject touching the screen to trace the spatial image, generating an audio-haptic feedback signal to inform the subject of distance discrepancies between the subject's touch position on the touch-screen and the original spatial image lines portrayed on the touch-screen to guide and improve the accuracy of the subject's tracing movements. ### Claim 2 (depends on 1) The method of claim 1, wherein said audio-haptic feedback signal is varied by altering an audio characteristic in response to said distance discrepancies, said audio characteristic being at least one of audio frequency, amplitude, timbre and pulse rate. ### Claim 3 (depends on 1) The method of claim 1, wherein the step of image exploration and memorization includes geometric parcellation of the spatial image information to direct attention to geometric relationships of components of the spatial image information. ### Claim 4 A method for improving a subject's spatial cognition and spatial memory, including: presenting spatial image information to the subject through a non-visual medium; non-visual exploration and memorization of the spatial image to enhance the subject's understanding of the nature and relationships of components of the spatial image information to promote augmentation of the subject's spatial image memory; the subject thereafter drawing ax image representation of the spatial image information; detecting and encoding errors it the image representation relative to the original spatial image; providing interactive feedback to the subject based on the subject's imam representation; wherein the step of image exploration and memorization includes geometric parcellation of the spatial image information to direct attention to geometric relationships of components of the spatial image information, and wherein said step of geometric parcellation includes directing the subject to analyze the spatial image information by at least one of the following tasks: identify line segments, identify inflection points, determine and describe spatial characteristics, both absolute and relative to adjacent line segments, segment-by-segment evaluation of line features, including segment orientation, length, angular relationships of segments, curvature of line segments and spatial configurational relationships among segments. ### Claim 5 (depends on 4) The method of claim 4, wherein said step of image exploration and memorization includes semantic parcellation of the spatial image information to examine semantic relationships of components of the spatial image information. ### Claim 6 (depends on 5) The method of claim 5, wherein said step of semantic parcellation includes directing the subject to identify the morphology and image-wise identity of components of the spatial image information, including deconstructing the image-wise component into commonly identifiable elements. ### Claim 7 (depends on 5) The method of claim 5, wherein said step of image parcellation includes integration of its subcomponents of geometric and semantic parcellation in an interwoven sequence of steps. ### Claim 8 (depends on 4) The method of claim 4, wherein the step of providing interactive feedback includes identifying discrepancies between the explored spatial image information and the drawn image representation, including at least one of a group of factors including: the overall scale of the drawing, global shape distortions, the omission of notable features, the strategy of sequencing the various lines in the drawing, the re-positioning of the drawing touch after being lifted from the drawing surface, the shapes of local image features, analyses in geometric or semantic nature, and strategies for global and local attention. ### Claim 9 (depends on 4) The method of claim 4, wherein the step of presenting spatial image information includes providing a tangible sheet of material with raised lines representing the lines in a line drawing, said raised lines being perceptible by finger touch. ### Claim 10 (depends on 4) The method of claim 4, wherein the step of presenting spatial image information includes providing a set of three-dimensional solid or wire-frame objects that portray the spatial image information. ### Claim 11 (depends on 4) The method of claim 4, further including the step of recording the hand movements of the subject's hand while carrying out the image exploration and memorization step using a recording device driven by the position of an exploratory tool [stylus, mouse, finger, keyboard] operated by the subject's hand. ### Claim 12 (depends on 4) The method of claim 4, further including the step of recording the hand movements of the subject's hand while the subject draws the image representation, using a recording device driven by the position of a drawing tool [stylus, mouse, finger, keyboard] operated by the subject's hand. ### Claim 13 (depends on 4) The method of claim 4, wherein the step of drawing the image representation is carried out by the subject while the subject is given tactile access to the spatial image information.
