Input device development by the use of BLE Technology and inertia sensors
The purpose of this paper is to describe the development of a pointing input device (mouse like device) by the use of inertia sensors. The device does not carry buttons in order to execute the ordinary commands of a mouse and also it doesn’t require a solid surface for the movement of the cursor. It’s a ring shaped gadget for ease in placement and the user can move the cursor of the host just by moving his arm. For command execution (left click) the ring is equipped with a gesture recognition algorithm which enables him to execute his command with a sudden movement of his finger. For the device’s interface, HID protocol has been used in order to enhance the interoperability of the device with all the major operating systems. For the communication with the host, BLE Technology is used providing ease in interconnection and large self-sufficiency.
