Input system

摘要

An input system includes an electronic device and a touchpad device. When the application program installed in the electronic device is activated, a target object is displayed on a display screen of the electronic device. A projection device of the touchpad device generates an object projection image of the target object. When the user moves the object projection image with the hand, the touchpad device detects a moving trajectory of the hand and generates the moved object projection image. Consequently, the target object shown on the electronic device is synchronously moved with the object projection image.

主权项

1. An input system, comprising:
an electronic device, wherein an application program is installed in the electronic device, wherein when the application program is activated, a target object is displayed on a display screen of the electronic device, wherein the electronic device generates a spatial information of the target object; and a touchpad device connected with the electronic device, and receiving the spatial information of the target object, wherein the touchpad device generates an object projection image of the target object according to the spatial information, wherein the touchpad device comprises:
a first projecting device disposed on a top surface of the touchpad device and located at a first side of the touchpad device, wherein the first projecting device generates a first projection image according to the spatial information, and the first projecting device generates a first optical signal according to a hand operation of a user on the object projection image;a second projecting device disposed on the top surface of the touchpad device and located at a second side of the touchpad device, wherein the second projecting device generates a second projection image according to the spatial information, and the second projecting device generates a second optical signal according to the hand operation, wherein the first projection image and the second projection image are collaboratively formed as the object projection image;an airflow sensor disposed on the top surface of the touchpad device, wherein the airflow sensor detects an airflow change according to the hand operation, thereby generating an airflow signal; anda controlling unit connected with the first projecting device, the second projecting device and the airflow sensor, wherein when the controlling unit receives the first optical signal, the second optical signal and the airflow signal, the controlling unit issues a first control signal to the electronic device, issues a second control signal to the first projecting device and issues a third control signal to the second projecting device, wherein the target object is controlled by the application program according to the first control signal, and the object projection image is moved according to the second control signal and the third control signal.
