Abstract: An object recognition method and an object recognition apparatus using the same are provided. In one or more embodiments, a real-time image including a first object is acquired, and a chamfer distance transform is performed on the first object of the real-time image to produce a chamfer image including a first modified object. Preset image templates each including a second object are acquired, and the chamfer distance transform is performed on the second object of each preset image template to produce a chamfer template including a second modified object. When the difference between the first modified object and the second modified object is less than a first preset error threshold, the object recognition apparatus may operate according to a control command corresponding to the preset image template.

Abstract: An optical-see-through head mounted display (HMD) system is provided. The optical-see-through HMD system has a camera for generating image frames, a display device and a processor. The processor proceeds an interactive operation on each image frame. In the interactive operation, an image analysis is performed on the image frame to obtain positioning information of a marker and 3-dimensional information of an input device. According to the positioning information, the 3-dimensional information and eye position of an user, an image shielding process is performed to correct a portion of the frame to be displayed which is corresponding to the input device and a collision test is performed according to the positioning information and the 3-dimensional information of an input device to determine whether the input device touches the virtual image displayed by HMD. Then, an event corresponding to the touch position of the virtual image is executed.

Abstract: A mobile device is provided, which includes a camera unit, a sensor unit, a see-through display, and a processor. The camera unit takes an image of a finger and a surface. The sensor unit generates a sensor signal in response to a motion of the finger. The taking of the image and the generation of the sensor signal are synchronous. The see-through display displays a GUI on the surface. The processor is coupled to the camera unit, the sensor unit, and the see-through display. The processor uses both of the image and the sensor signal to detect a touch of the finger on the surface. The processor adjusts the GUI in response to the touch.
