Abstract

A tactile sticker is disclosed. The tactile sticker of the present invention comprises a thin resin layer, a first adhesive layer, and tactile protrusions. The thin resin layer is adhered to the surface of an electronic product by the first adhesive layer. Tactile protrusions that can be read by a finger are attached to the upper surface of the thin resin layer. The tactile protrusions include a meaning notification portion, a button location notification portion, and a button location guide portion. The meaning notification portion includes one or more forms selected from Braille, symbols, letters, and numbers. The button location notification portion is spaced apart from the meaning notification portion. The button location notification portion indicates the location of a touch button on the surface of the electronic product. The button location guide portion extends in a linear form from the periphery of the meaning notification portion to the button location notification portion.

Description

Tactile Sticker The present invention relates to a tactile sticker, and more specifically, to a tactile sticker that allows a visually impaired person to perceive and operate a touch button of a home appliance by touch. Most people use their vision to distinguish objects in their living spaces. On the other hand, those with visual impairments use touch instead of sight, but it is difficult to perceive everything at once, and the range of perception is limited. Consequently, users with low vision or total blindness cannot easily obtain information about their living spaces, and touch interfaces on home appliances are exacerbating these difficulties. To use home appliances, users must be able to distinguish and locate each function button without causing errors, press the desired function button, and repeatedly press the button until the desired option is set. However, when users with low vision or total blindness attempt to operate a touch interface made of a smooth surface, they are unable to locate the touch buttons or accurately select the desired function button due to the lack of height differences between the buttons. In this regard, Korean Published Patent No. 2023-0014223 (hereinafter referred to as the "prior art") discloses a "sticker-type braille film (bramza stickers)," wherein the sticker-type braille film (bramza sticker) comprises a printed paper, an adhesive layer, and a release liner. Braille protrusions that can be detected by touch by a visually impaired person are formed on one side of the printed paper. An adhesive layer is formed on the other side of the printed paper. A release liner is detachably attached to the adhesive layer. The user peels off the backing paper and attaches the Braille sticker to a button on an item or device for use. According to the aforementioned prior art, while Braille protrusions can form letters such as Korean, numbers, and English, there is a usage limitation that they can only be applied to buttons that match specific characters. Since touch buttons on home appliances operate with just a light touch, braille protrusions must be positioned around the buttons. In other words, visually impaired individuals must first touch the protrusions with their fingertips to recognize the function and location of the touch button before touching it. However, visually impaired individuals can only perceive the approximate location of the touch button based on the protrusions, making it difficult to accurately determine its position. In addition, when a braille sticker is attached to a curved or uneven surface of a home appliance, the printed paper may not adhere completely to the appliance, and a small gap may occur between them. Furthermore, as one side of the printed paper with the protrusions attached forms a curve, the bonding force between the one side of the printed paper and the protrusions is weakened, which may cause the protrusions to detach from the one side of the printed paper. Furthermore, as the printed paper and adhesive layer form a certain thickness on the surface of the home appliance, the Braille sticker is easily visually distinguishable on the surface. Even if the printed paper is manufactured from a transparent material, it may compromise the appliance's originally intended design by forming a reflectivity different from the appliance's surface.
