Embodiments relate generally to devices for vision impaired persons, and, more particularly to a film and decal having a tactile relief surface to indicate an object characteristic such as color.
At least one embodiment can include a tactile relief film or decal made from rubber or plastic, for purposes of creating raised markings for reading and recognition by the visually impaired. The film or decals can be formed from a transparent material such that the color of the underlying object that the film or decal is applied to is visible to a person who can see color. The film/decal may be applied during production at the manufacturing phase or may be applied post-production.
At least one embodiment can make it possible for a user to determine colors of objects and their parts, component elements, or the like by feel or touch through use of tactile recognition (similar to the way Braille markings are used). Tactile relief films or decals indicating colors in accordance with at least one embodiment can be applied to objects such as toys and pencils, for example. One or more embodiments can include abbreviated versions of words or descriptions that may be utilized to reduce response time and increase perception. Also, the tactile reliefs can resemble known objects or patterns, and thereby assist with the identification of the symbol or color. For example, the tactile relief may resemble the surface of an orange for identification of the color orange.
At least one embodiment can include a film/decal having a relief that can be easily identifiable and familiar, in terms of use in this particular application.
Also, in at least one embodiment, a tactile relief for indicating color in accordance with the present disclosure can be molded, stamped or formed directly on a surface of an object. Alternatively, an embodiment can be applied to a surface as an adhesive film, decal or sticker.
An embodiment can permit more rapid recognition of identifiers such as color than is offered by traditional methods that require the reading of a word to identify the trait or characteristic (e.g., Braille). In this respect, an embodiment can facilitate increased socialization and integration. Also, by providing a more easily learned and/or recognized tactile relief surface, an embodiment can be used by persons having color blindness as their only uncorrectable vision impairment. Thus, a color blind person, who has no need to learn the Braille system, can learn the disclosed color indicating tactile relief system, which can be limited to indicating colors or other characteristics.
The relief elements are preferably of sufficient height to permit tactile recognition by either a vision impaired person or a person without vision impairment other than colorblindness, while not interfering with proper functioning of an object. Decals, film or sticker can be made from a transparent, non-rigid, durable material such as rubber or some plastics.
At least one embodiment can include a relief texture-to-color mapping system such as, for example, the following:
At least one embodiment can be used for the designation of the texture of cloth, clothing, wall-papers, relief of furniture, dishes or the like. For example, an embodiment can contain information regarding the surface of an object, its form, shape, texture, or the like. For persons with unimpaired vision, the tactile relief surface, film or decals can be used to identify objects or characteristics of objects where illumination is not available or where visual utility is limited. An embodiment can also include a phosphorescent or “glow in the dark” material integrated into the sticker or decal material or applied as a coating to stickers or decals.
The tactile relief surface texture can correspond to the colors according to the following table:
In use, the stickers can be applied to objects to permit a person having a visual impairment (e.g., full or partial sight, color blindness, or the like) to use tactile sensation to determine the color of an object.
In addition or as an alternative to indicating colors, the stickers can be used to indicate other characteristics of an object such as weight (e.g., heavy or light), type of surface (e.g., smooth or rough), type of the end of the object (e.g., sharp or dull), type of its hardness (e.g., hard or fragile) or the like.
In operation, a person with impaired vision or a person in low visibility can use tactile senses to determine which buttons are which on the keypad. It will be appreciated that other types of keypads can be used such as computer keypads, or the like. Also, it will be appreciated that the relief moldings or stickers could be placed on any type of keypad or button for controlling and electrical and/or mechanical device.
The stickers can also be impregnated, treated or coated with a phosphorescent or glowing material so that the location of the sticker (or film or decal) can be visible in low light.
In addition to the exemplary applications discussed above, tactile relief stickers, decals or moldings in accordance with at least one embodiment could be used on TV (or other electronic device) remote control buttons. An embodiment could also be used on games that rely on color, such as the Rubik's cube, to enable a person with a vision impairment (e.g., full or partial blindness or full or partial color blindness) to play the game.
It is, therefore, apparent that there is provided, in accordance with the various embodiments disclosed herein, tactile relief surfaces, films and decals for tactile indication of color or other object characteristics, traits or features.
While the invention has been described in conjunction with a number of embodiments, it is evident that many alternatives, modifications and variations would be or are apparent to those of ordinary skill in the applicable arts. Accordingly, Applicant intends to embrace all such alternatives, modifications, equivalents and variations that are within the spirit and scope of the invention.
