          Question:describe the most fantastic input and output devices in the near future

 

As far as i am concerned, I hold on the opinion that the fantastic input and output devices in the near future is the most useful and convenient devise. Compared with the traditional input and output devices, the devices of future are more fast, and can provide people with better services. Now, let me introduce for you:

 

          Input device:

Brain wave input(脑电波输入): illusions such a future - brain waves and chips to achieve direct transmission, half robot's science fiction face.

 

Smart glasses(智能眼镜): smart glasses are probably the most promising wearable input devices, because it's very close to our main sensory organs - the eyes, and this brings a lot of development. Most smart glasses use the OHMD (optical head mounted display) technology to project the screen to the eyes, and the OHMD can provide a real mobile viewing experience with other input methods such as the voice command system used by Google glasses. Companies such as Swedish Tobii have used the eye tracking system as an input device solution. By tracking the movement of the eyeball to determine the direction of eye stay, such a system can be used to execute commands, and the application fields have traditional workstations, cars and even video games.

 

Three-dimensional scanner: It is a kind of advanced three-dimensional model input device. It is an important tool for three-dimensional modeling of actual objects currently used. It can quickly and easily convert real-world three-dimensional color object information into digital signals that can be directly processed by computers, providing an effective means for digitization of physical objects.

 

 

          Output device:

3D stereo glasses: The system consists of a three-dimensional graphics accelerator card, an infrared control transmitter box, a set of wired and a set of wireless stereo glasses, support for high resolution, high field frequency, progressive stereo display.

 

 

3D display: 3D displays use parallax illumination technology. The two images for the left eye and the right eye are respectively transmitted to pixel blocks in different areas, odd blocks represent left eye images, and even blocks represent right eyes.
