Control system, mouse and control method thereof

A mouse used with a dongle, the dongle being wiredly connected to a host and having a first light source for emitting a first light, the mouse being wirelessly connected to the dongle and comprising:

• a transmitter;
• a second light source, being configured to emit a second light;
• a single light sensor, being configured to, according to a schedule defining a first time interval and a second time interval, sense the first light through a first light guide path to generate a first sensing signal at the first time interval, and sense the second light through a second light guide path to generate a second sensing signal at the second time interval, wherein the first time interval and the second time interval are not overlapped to each other;
• and
• a processor electrically connected to the transmitter and the single light sensor, being configured to generate a first control signal according to the first sensing signal, generate a second control signal according to the second sensing signal and transmit the first control signal and the second control signal to the dongle via the transmitter so that the host receives the first control signal and the second control signal via the dongle.

A control method for a mouse, the mouse being used with a dongle and being wirelessly connected to the dongle, the dongle being wiredly connected to a host and having a first light source for emitting a first light, the mouse comprising a transmitter, a second light source, a single light sensor, and a processor, the second light source being configured to emit a second light, the processor being electrically connected to the transmitter and the single light sensor, the control method being executed by the processor, and comprising:

• enabling the single light sensor to, according to a schedule defining a first time interval and a second time interval, sense the first light through a first light guide path to generate a first sensing signal at the first time interval, and sense the second light through a second light guide path to generate a second sensing signal at the second time interval, wherein the first time interval and the second time interval are not overlapped to each other;
• generating a first control signal according to the first sensing signal;
• generating a second control signal according to the second sensing signal;
• and
• transmitting the first control signal and the second control signal to the dongle via the transmitter so that the host receives the first control signal and the second control signal via the dongle.
