The device’s four buttons allows the click functions of the mouse to be performed: left click, right click, double click, drag-drop. The function of each button can be assigned using the BJOY configuration software.

This device can be customised on demand so that external switches can be connected. The switch inputs would correspond to the buttons A, B, C, D indicated in the product and in the configuration software. 

In order to use the BYoy Hand C mouse you have to connect the connection cable to the computer’s USB port. Once the computer has recognised the device you can use the mouse.

In order to move the cursor you just have to move the joystick in the desired direction. The cursor will move following 4/8 specific directions depending on how it is configured. The cursor will move at the configured speed regardless of the inclination of the joystick lever.

For the clicks you have to use the buttons A, B, C and D indicated on the device. By defect the following functions are assigned to these buttons:

Entry A: Left click
Entry B: Right click
Entry C: Double click
Entry D: Drag – drop

The drag function is activated by pressing the button once. The cursor is then activated as if the left click was being pressed. Use the joystick in order to drag to the desired place. To deactivate this function the drag button must be pressed again.

Take into account that both the actions on the buttons and the movements of the cursor can be configured using the configuration software which is described below.

The BJOY configuration software allows you to configure the mouse behavior according to the user needs.
