Now-a-days, sensors are of low cost and are very easily available. wireless networking is enabling ways in which people can interact with their smart homes. Many approaches like using voice commands are emerging. This paper shows the design and implementation of a low-power, low-cost, hand-held wireless device to interact with home appliances. These devices are gesture-based control system to operate home appliances and as to make smart homes more advanced and easy for people to control devices across them. We can control all the home devices by using leap motion sensor by assigning a different gesture for different home devices. Simple gestures can be used to control these home appliances. Ad-hoc wireless network using the ZigBee protocol can be used to control home appliances. The gestures in each device can be customized to control home appliances. This can be extended to collect gesture based commands for different persons and apply Artificial Intelligence (AI) principles for learning and improving the controls based on gestures of different individuals.
