The present invention discloses a method for outputting a command by detecting a movement of an object, which includes the following steps. First, an image capturing device captures images generated by the movement of the object at different timings by. Next, a motion trajectory is calculated according to the plurality of images. Further next, a corresponding command is outputted according to the motion trajectory. The present invention also provides a system which employs the above-mentioned method.

Method for outputting command by detecting object movement and system thereof

The present invention provides a motion detecting system, which includes a light source module, a plurality of image sensors and a control unit. The light source module illuminates at least one object. The image sensors respectively detect the object under the light emitted by the light source module to generate a plurality of detection results. The control unit is coupled to the image sensors, and generates a control command according to the detection results.

Motion detection system having two motion detecting sub-system

Glasses with gesture recognition function include a glasses frame and a gesture recognition system. The gesture recognition system is disposed on the glasses frame and configured to detect hand gestures in front of the glasses thereby generating a control command The gesture recognition system transmits the control command to an electronic device to correspondingly control the electronic device.

Interactive system and device with gesture recognition function

There is provided an optical navigation device including an image sensor, a processing unit, a storage unit and an output unit. The image sensor is configured to successively capture images. The processing unit is configured to calculate a current displacement according to the images and to compare the current displacement or an accumulated displacement with a threshold so as to determine an outputted displacement. The storage unit is configured to save the accumulated displacement. The output unit is configured to output the outputted displacement with a report rate.

Optical device and locus smoothing method thereof

An input system includes a first gesture detection unit and a second gesture detection unit. The first gesture detection unit includes a first light emitting device for emitting a first light beam, a first light sensing device for receiving the first light beam reflected by a first motion trajectory generated by a user and outputting a first image signal, and a first processing unit for processing the first image signal and outputting a first command signal. The second gesture detection unit includes a second light emitting device for emitting a second light beam, a second light sensing device for receiving the second light beam reflected by a second motion trajectory generated by the user and outputting a second image signal, and a second processing unit for processing the second image signal and outputting a second command signal.
