Abstract
There is provided an intuitive, easy-to-use operation interface that is less liable to erroneous operations and is operated by a motion of a user. A motion operation mode is entered in response to recognition of a particular motion (preliminary motion) of a particular object in a video image and, after that, operation of any of various devices is controlled in accordance with various command motions recognized in a motion area being locked on. When an end command motion is recognized or after the motion area is unable to be recognized for a predetermined period of time, the lock-on is canceled to exit the motion operation mode.
Claims36
A control apparatus which controls an electronic device, comprising:
- a video image obtaining unit which continuously obtains a video signal a subject of which is a particular object;
- a command recognition unit which recognizes a control command relating to control of the electronic device, the control command being represented by at least one of a particular shape and motion of the particular object from a video signal obtained by the video image obtaining unit;
- a command mode setting unit which sets a command mode for accepting the control command;
- and
- a control unit which controls the electronic device on the basis of a control command recognized by the command recognition unit, in response to the command mode setting unit setting the command mode.
A control apparatus which controls an electronic device, comprising:
- a video image obtaining unit which continuously obtains a video signal a subject of which is a particular object;
- a command recognition unit which recognizes a preliminary command and a control command relating to control of the electronic device from a video signal obtained by the video image obtaining unit, the preliminary command and the control command being represented by at least one of a particular shape and motion of the particular object;
- and
- a control unit which controls the electronic device on the basis of a control command recognized by the command recognition unit, in response to the command recognition unit recognizing the preliminary command;
- wherein the command recognition unit tracks an area in which a preliminary command by the particular object is recognized from the video signal, and recognizes the control command from the area.
A control apparatus which controls an electronic device, comprising:
- a video image obtaining unit which continuously obtains a video signal a subject of which is a particular object;
- a command recognition unit which recognizes a preliminary command and a control command relating to control of the electronic device from a video signal obtained by the video image obtaining unit, the preliminary command and the control command being represented by at least one of a particular shape and motion of the particular object;
- a command mode setting unit which sets a command mode for accepting the control command, in response to the command recognition unit recognizing the preliminary command;
- and
- a control unit which controls the electronic device on the basis of the control command in response to the command mode setting unit setting the command mode;
- wherein the command recognition unit, in response to the command mode setting unit setting the command mode, tracks an area in which a preliminary command by the particular object is recognized from the video signal and recognizes the control command from the tracked area.
23 The control apparatus according to claim 8, wherein the command recognition unit recognizes a selection confirmation command to confirm selection of a menu item from a particular shape of the particular object.
The control apparatus according to claim 23, wherein the selection confirmation command is represented by formation of a ring by fingers.
