Gesture Based Alternative To Control Recreational UAV

The arrival of Unmanned Aerial Vehicles (UAV) to the common mar-ket has been changing the way we interact with our surroundings. Fields like cinema and photography are improving with the possibility of reaching unsafe areas, as much as industry related companies that can now supervise their infra-structures safely. Besides many other professional areas, this fever also got into sports and UAV racing became a new way to compete. There are limited alterna-tives to control a UAV, each one with its pros and cons. The most reliable is the conventional handheld controller, a bulky equipment that requires practice and dexterity to be a good pilot. Consequently, technologically illiterate individuals, users with low dexterity or hand malformations and elders are departed from this game breaking technology, either for professional or recreational purposes. To expand the control of UAV to more member of our society, a different control equipment should be developed. In this paper we propose a solution based in two lightweight hand worn devices sensitive to motion changes. These changes are used to detect changes in the orientation of the device, which are then transmitted through Bluetooth Low Energy (BLE) to a mobile app that is responsible for in-terpret them as simple input or input patterns. The result of this interpretation should be used as flight commands to control a UAV. Through simple and intui-tive hand movements, users can accurately pilot a quadcopter. This alternative presents a new and easier approach to control UAV that decreases the time that is required to learn how to use it, which on an accentuated learning curve. The results obtained with the usability tests performed with users with different ca-pacities of interaction, confirmed the viability of this solution, as much as its simplicity and intuition in the control.
