Phase II year
1986
(last award dollars: 1987)
Phase I determined that particles, activated by heat, pressure, chemicals, or other means, can be encapsulated in a paper material; this material, when stimulated, will provide immediate, colored, raised impressions. Both the color contrast and the tactile reinforcement will benefit low-vision persons; the tactile impression will benefit the blind. The active agent, encapsulated in a selected paper, will be stimulated by an imaging pen, allowing the user to draw or write in free-hand fashion, causing a colored, raised impression. No equipment other than the paper and pen will be required. Existing enhancement devices and techniques require training and equipment, or are inadequate.Development of this pen-and-paper device will lessen the isolation of the visually handicapped and will provide a communication tool available to both handicapped and nonhandicapped. Visually handicapped individuals and schools, employers, and agencies serving the visually handicapped constitute a significant market for commercialization of this innovation.Phase II will involve field-testing and evaluation of several tactile-encapsulated papers that were determined to be technologically and economically feasible in Phase I. Populations of the visually handicapped, including a variety of forms of visual impairment and subject age, have been identified for the assessment of which paper offers maximum satisfaction and capability.
