Description

Photosensitive tactile system and photosensitive method thereof

The invention relates to a sensing system and a sensing method, in particular to a photosensitive tactile system and a photosensitive method thereof.

The human sensory system is located in the nervous system, and its main function is to process sensory information, and the sensory system includes sensory receptors, neural pathways, and cerebrum ), the part related to sensation or perception. Thus, the sensory system senses sight (eyes), hearing (ears), touch (skin and hair), taste (tongue), and smell (nose). Under normal circumstances, the brain has the highest absorption rate of visual input, up to 83%, 11% of auditory input, 3.5% of olfactory input, and 3.5% of tactile input. It can reach 1.5%, and the absorption rate of taste input information is the lowest, only reaching 1%. It can be seen that vision is a very important sense for human beings, and in vision, color and three-dimensional perception are mainly produced.

When there is light (light), humans can produce vision, and light is an electromagnetic wave (electromagnetic wave), and color is formed by electromagnetic waves of different wavelengths stimulating the cone photoreceptor cells (cones) on the retina of the eye. When three After the cone cells are stimulated by light, they will generate an impulse and transmit it to the visual cortex of the brain. The three types of cone cells have different photosensitive curves, so a variety of different feelings are combined in the visual cortex. , and different feelings lead to different color cognition. Electromagnetic waves here can be expressed as spectral energy distribution, and can also be expressed as a function of wavelength, and not every electromagnetic wave of a wavelength can irritate the eyes, only the wavelengths between 380 nm and 780 nm Light that irritates the eyes is called visible light.

The color mentioned above is completely the perception of the eyes, that is, the color is the perception produced by the brain, rather than existing in the environment, so human beings' cognition of color is learned from the day after tomorrow, not innate . Vision is an important perception for human beings. Therefore, for the visually impaired, it can only be touched by finger touch, such as Braille, to assist reading, but because fingers cannot be touched by touch. Knowing the color, how to provide a miniaturized and highly reliable color auxiliary electronic device will be a very important issue. In view of this, the industry is in great need of a photosensitive tactile system and method capable of providing photosensitive tactile sensation, which can fill or compensate for the photosensitive tactile sensation that cannot be provided by current conventional technologies.

In order to achieve the above object, the present invention provides a photosensitive tactile system, which includes: a tactile device, which is arranged on a user's finger, and senses the color of the luminous body by touching the luminous body. The tactile device includes: a photosensitive element , used to sense the luminous body, according to the detected first color, second color and third color, correspondingly generate the first current, the second current and the third current respectively; the converter is electrically connected to the photosensitive element , receiving the first current, the second current and the third current transmitted by the photosensitive element, the converter distinguishes the first current, the second current and the third current and generates first a current value, a second current value and a third current value; and a first transceiver electrically connected to the converter for wirelessly transmitting the first current value, the second current value and the third current value; and, The portable wearable device includes a display element and a second transceiver, and the second transceiver wirelessly receives the first current value, the second current value and the third current value; wherein, the portable wearable device according to the first A current value, the second current value and the third current value determine the ratio values of the three primary colors, and judge the color of the luminous body according to the ratio values.
