What is a touch hologram?
Touch hologram is a combination of apparently three -dimensional light projections, a sensor field and some type of tactile feedback. It is impossible to really touch and feel holograms, but the use of a sensor field and haptic technology can provide the illusion of touch. Sensors are used so that the computer can adjust the behavior of holographic projection when it touches, and haptics are used to provide a real sensory input. A number of different haptic technologies can be used to create a touching hologram, although ultrasound has been selected for some of the first designs. This type of projection can be viewed from any angle as well as a physical object, even if it consists of nothing but lights. Since holograms are made of light and lack any physical substance, they cannot be affected by them or communicate with them through traditional means. All right to create a touch hologram, at least two different techniques must be used.
In order for a hologram to be felt, some type of haptic technology must be used. One way to create tactile feedback is to attach physical devices to the hands or body of a person, even if it may disrupt the illusion of touch of hologram. Another option is high -performance air nozzles, although ultrasonic devices can provide a similar effect. In both cases, haptic technology is used to give the physical feeling of some part of the human body to ensure the illusion of touch.
The second main component necessary for creating a touch hologram is some type of sensor device. In order for haptic technology to be activated at the right time, the computer must know where the hand or other part of the body is located. This can be achieved using a camera and specialized software, although reflective tape and other brands can be more accurate. Once the computer knows where the hand of a person is located, it can activate haptic technology in correctThe time to create the illusion of touch.
These types of sensors can also enable a person to interact with hologram. Because the computer responsible for generating and controlling the image and the haptic feedback knows where the person is, it can respond appropriately. An example of this type of touch hologram is a ball that is able to bounce someone's hand. The computer can follow the location of the hand, project the hologram in the right place and activate tactile feedback accordingly. If the hand is moved, the ball can be allowed to drop realistically.
