Bulbs control in virtual reality by using leap motion somatosensory controlled switches

This study presented a Leap Motion somatosensory controlled switches. The switches were implemented by the relays. The “open” or “short” of the switching circuit were controlled by the sensing of the Leap Motion somatosensory module. The virtual switches on the screen have designed to be 5 circle buttons. When the sensing hand touched the circle buttons virtually, the programming language “Processing” sent the instruction codes to the Arduino MEGA module which gave the “high” and “low” signal to the transistor switches. Therefore, a four-channel Leap Motion somatosensory controlled switching module has been implemented. For testing the module, the bulbs have been connected with the switching module. Consequently, the “light” or “dark” of LED modules can be controlled by touching the virtual buttons on the screen.
