Electronic device for controlling host device by using motion signal and mouse signal

An electronic device which is paired with a host device to control content of the host device, comprises:

• a touch sensing module including a surface divided into a first touch region, a second touch region, and a third touch region;
• a movement sensing module for acquiring first movement information in a three-dimensional space of the electronic device based on an accelerometer, a gyroscope, and a magnetometer;
• a control signal output unit for acquiring second movement information through operation of the first movement information, and determining, under a gesture mode, a motion corresponding to the movement of the electronic device based on the second movement information and outputting a motion signal indicating the determined motion to the host device, and determining, under a mouse mode, a mouse action based on at least one of touch information acquired from the touch sensing module and the second movement information and outputting a mouse signal indicating the mouse action to the host device;
• a case for embedding the touch sensing module, the movement sensing module, and the control signal output unit;
• and
• a cradle device for receiving the case and closing a lid or opening the lid so as to take out the case,
• wherein:
• the first movement information includes at least one of acceleration data obtained through the accelerometer and angular velocity data obtained through the gyroscope;
• the movement sensing module transmits the first movement information to the control signal output unit through an internal bus;
• the second movement information includes at least one of angle data, distance data, velocity data, and direction data;
• the mouse signal includes a mouse click, a mouse scroll, a mouse move, or a mouse drag;
• switching between the mouse mode and the gesture mode is performed by a touch action sensed by the touch sensing module;
• a center of gravity pendulum is positioned at the bottom of the cradle device;
• when the case is accommodated in the cradle device and the lid is closed, the first touch region, the second touch region, and the third touch region for the touch action are exposed, when a user moves while holding the cradle device in his or her hand, or touches the exposed first touch region, the second touch region, or the third touch region, the motion signal or the mouse signal is output;
• when the user moves the case while wearing the case separated from the cradle device on a finger or touches the first touch region, the second touch region, or the third touch region, the motion signal or the mouse signal is output;
• the control signal output unit determines, under the mouse mode, the mouse move from the second movement information, wherein:
• if a touch action sensed by the touch sensing module is a touch only to the first touch region or a simultaneous touch to the first touch region and the second touch region, the mouse action is determined as the mouse click;
• and
• if a touch action sensed by the touch sensing module is a sequential touch to the first touch region, the second touch region, and the third touch region, the mouse action is determined as the mouse scroll.
