NTT has devised a pin display that non-electrically presents visual and tactile information based on a magnetic field pattern written on a magnetic sheet.
Unlike conventional pin displays that display shapes and braille by moving multiple pins up and down, NTT have realized the world’s first control method that does not use an electric actuator to drive the pins.
You can check in advance what kind of movement will be presented by changing the pin arrangement and the pitch of the magnetic field pattern. , Heart-shaped and circular ripples can also be expressed.
An electric actuator is a device that converts given electric energy into physical movement of a machine. It is converted into rotary motion and vertical motion by a motor or an electromagnet.
This research and development proposes an information presentation interface that aims to achieve both affluence and environmental conservation by replacing some of the interaction technology that has been electrically implemented so far with non-electrical mechanisms. It is expected to be used in educational settings, as an accessory for small robots, and as a tactile display that does not require a power supply.
