DETAILED DESCRIPTION
Electronic devices within a residence may be controlled based on gestures made by a user. The gestures may allow for user control of one or more devices without the need for the user to hold, wear, or be in contact with a sensor or a remote control device. Gestures of a user may be detected by a three dimensional (3D) image device. Data from the 3D image device may be analyzed by a gesture controller to determine whether gestures made by the user should be ignored, should result in sending a menu to a display device, should result in navigation of the menu, should result in selection of menu options, or should result in the gesture controller sending at least one command to one or more devices. The gesture controller may replace a remote control device, may be used when the user does not desire to use or cannot easily access the remote control device, or may be used when the user wants to control a device that is able to be controlled using the gesture controller but is not able to be controlled by the remote control device.
In a particular embodiment, a system includes a three dimensional (3D) image device configured to provide 3D image data of movements of a user. The system includes a display interface configured to send options of a menu to a display device. The system includes a processor configured to analyze the 3D image data to provide at least one of an instruction to change the menu and at least one command for one or more devices. The system also includes at least one interface to send the at least one command to the one or more device.
In a particular embodiment, a method includes sending a menu from a gesture controller to a display device. The menu includes selectable options to control at least one electronic device. The method includes detecting a first user gesture at the gesture controller in response to three dimensional (3D) image data obtained from a gesture camera. The method includes determining at least one command for one or more electronic devices at the gesture controller based on the first user gesture and based on the menu. The method also includes sending the at least one command from the gesture controller to the one or more electronic devices.
FIG. 1 is a block diagram of a particular embodiment of a system 100 that includes a gesture controller 102 for device control based on gestures. The gesture controller 102 may be in a residence 104. The gesture controller 102 may be coupled via a wired connection or a wireless connection to one or more devices 106-120 that are to be controlled. The devices 106-120 may include, but are not limited to, customer premises equipment (CPE) 106, at least one media device 108, at least one display device 110, at least one computer system 112, a security system 114, one or more electronic devices 116 associated with the residence 104, lighting 118 associated with the residence 104, and at least one mobile communication device 120.
The gesture controller 102 may receive three dimensional (3D) image data from a gesture camera 122. The gesture camera 122 may be an integral component of the gesture controller 102, or the gesture camera 122 may have a wired or wireless data connection with the gesture controller 102. The gesture controller 102 may analyze the 3D image data from the gesture camera 122 to determine one or more gestures made by a person within range of the gesture camera 122. Certain gestures detected by the gesture controller 102 may cause the gesture controller 102 to send information to the display device 110 (e.g., a menu), to change information sent to the display device 110 (change or update a menu sent to the display device 110), or may cause the gesture controller 102 to send commands to one or more of the devices 106-120. The information may be sent directly to the display device 110, or the information may be sent to the display device 110 via another device (e.g., via the media device 108).
The gesture camera 122 may be any type of camera able to provide 3D image data to the gesture controller 102. For example, the gesture camera 122 may include two or more offset camera lenses that allow combined 3D image data to be generated. In another example, the gesture camera 122 may include a lens, an emitter (e.g., an infrared emitter), and a receiver that allows 3D image data to be generated. Gesture cameras 122 may be available from several companies, including Canesta, Inc. (Sunnyvale, Calif.), PRIMESENSE Ltd. (Tel-Aviv, Israel), and MICROSOFT Corporation Inc. (Redmond, Wash.).
The CPE 106 may facilitate communications between one or more devices (e.g., the media device 108) and one or more content providers 124 via a network 126. The CPE 106 may include a router, a wireless router, a local area network device, a modem (e.g., a digital subscriber line (DSL) modem or a cable modem), a residential gateway, other communication facilitator, or combinations thereof.
The media device 108 may be a set-top box device or similar device that receives media content from the one or more content providers 124 via the network 126. The media content may be provided to the display device 110 or to other electronic devices (e.g., the computer system 112). The media content may be television programming, video-on-demand, internet content, or other types of media. The media device 108 may provide a user interface to the display device 110 that allows the person to change settings of the gesture controller 102. A remote control device may be used to control at least the media device 108 and the display device 110.
The computer system 112 may be a desk top computer, a lap top computer, or a tablet computer. The computer system 112 may be able to provide a user interface that allows the person to change settings of the gesture controller 102.
The security system 114 may provide security services for the residence 104. The services may include, but are not limited to, monitoring windows, doors, motion detectors, fire alarms, carbon monoxide alarms, other devices, and combinations thereof for alarm conditions; controlling electronic locks; controlling lighting; and combinations thereof. The security system 114 may inform (e.g., by an alarm, by display on the display device 110, by phone, by email, by text messages, etc.) people in the residence 104, specific individuals, authorities, or combinations thereof, when one or more alarm conditions occur at the residence 104. The authorities may be personnel of a security company, local police, local firefighters, medical personnel, other service personnel, or combinations thereof.
The electronic devices 116 may include, but are not limited to, audio equipment (e.g., stereo receivers, compact disc players, etc.), video equipment (e.g., digital video disc players, digital video recorders, etc.), thermostats associated with heating/cooling systems for the residence 104, telephones, base stations for mobile telephones, kitchen appliances, or other devices that can be controlled via received signals. For example, the electronic devices 116 may be controlled to turn the electronic devices 116 on or off. In another example, the electronic devices 116 may be controlled to perform more complex functions, such as increment or decrement a channel; increase or decrease volume, temperature, light intensity, rewind speed, or fast forward speed; forward an incoming phone call to voice mail, or other electronic device function.
The lighting 118 in the residence 104 may include lights in various rooms in the residence 104, lights outside of the residence 104, or both. The lighting 118 may be turned on or turned off by commands from the gesture controller 102. Additionally or in the alternative, intensity of the lighting 118 may be changed in response to commands from the gesture controller 102 (e.g., when particular lights are controlled by dimmer switches).
The mobile communication device 120 may be able to couple to a wireless communication network. The mobile communication device 120 may connect to the network 126 via the CPE 106. The presence of the mobile communication device 120 in the residence 104 or in a particular area of the residence may 104 be detected by the CPE 106, the media device 108, the computer system 112, a base station for the mobile communication device 120, a femtocell coupled to the CPE 106 to provide strong signal for the mobile communication device, another electronic device, or combinations thereof. When the mobile communication device 120 is detected near the display device 110, the gesture controller 102 may send to the display device 110 a notification of an incoming call to the mobile communication device 120 and may provide options regarding on how to handle the incoming call. The mobile communication device 120 may be near the display device 110 when the mobile communication device 120 is in the residence 104 or when the mobile communication device 120 is in the same room as the display device 110.
The gesture controller 102 may include a processor 128, one or more interfaces 130 coupled to the processor 128, and a memory 132 coupled to the processor 128. The one or more interfaces 130 may receive signals from, and transmit signals to, the devices 106-120. The one or more interfaces 130 may include wired interfaces and wireless interfaces. For example, the interfaces 130 may include, but are not limited to, a network interface, a display interface, a structural wiring interface, an infrared interface, an X10 interface, and combinations thereof.
The memory 132 may include settings 134, device information 136, one or more drivers 138, and instructions 140. The settings 134 may specify which devices 106-120 in the residence 104 are to be controllable with the gesture controller 102. The settings 134 may also allow user defined gestures to be stored and utilized, may define what gestures activate a control session, what gestures end a control session, what gestures navigate menus, what gestures select options, and what gestures specify particular commands for the devices 106-120. A single gesture may be used to provide commands to different ones of the devices 106-120. For example, the gesture of raising or lowering an arm may be specified in the settings 134 to raise or lower volume associated with the display device 110, to raise or lower volume of one or more of the electronic devices 116 (e.g., a stereo system or a radio), and to dim or brighten lighting 118 that is coupled to a controllable dimmer switch.
The settings 134 may be accessed via a user interface displayed on the display device 110. For example, the media device 108, the computer system 112, the gesture controller 102, or another device may send the user interface to the display device 110. The user interface to change the settings 134 may be accessible via the computer system 112 or via a device other than the display device 110.
The device information 136 may include information regarding devices to be controlled (e.g., the devices 106-120 identified in the settings 134). The device information 136 for a particular device may include, but is not limited to, an address or identifier used to communicate with the particular device, which particular interface of the interfaces 130 is to be used to communicate with the particular device, and which driver of the drivers 138 is to be used to provide instructions for particular commands to be implemented by the particular device. When a new device is added to the settings 134, an address or identifier used to communicate with the new device may be added manually, or the gesture controller 102 may automatically determine the address or identifier for the new device.
The drivers 138 may provide instructions that are sent to the devices 106-120 to implement commands. When a new device is added to the settings 134, the user interface may provide an option to provide or identify an existing driver for the new device, or the user interface may provide an option to obtain the driver from the content providers 124 via the network 126. A particular driver of the drivers 138 may be specific to a single device (e.g., to the media device) or may be applicable to many devices (e.g., to individual lights of the lighting 118). The gesture controller 102 may include instructions to periodically or occasionally search for and obtain updated drivers for the devices 106-120 that the gesture controller 102 is able to control via the network 126.
The instructions 140 may include code executable by the processor 128 to perform particular tasks. To simplify the description, the instructions 140 are shown as separate functional modules with each functional module associated with particular tasks. For example, the instructions 140 may be separated into a determine module 142, a menu module 144, and a send module 146.
The determine module 142 may be executed by the processor 128 to process 3D image data from the gesture camera 122. When the determine module 142 is running, the processor 128 may analyze the received 3D image data to determine when a recognized gesture is made by a person within range of the gesture camera 122. Recognized gestures may include, for example, an initiate gesture, an end gesture, a navigation gesture, and a select gesture. The initiate gesture may be used to begin a gesture session. For example, when the determine module 142 detects a person near the gesture camera 122 performing the initiate gesture, the gesture controller 102 may send a menu to the display device 110. The gesture controller 102 may ignore gestures made by one or more people in range of the gesture camera 122 until the initiate gesture is detected. When more than one person is in range of the gesture camera 122, the running determine module 142 may cause the processor to identify one or more characteristics of a person who made the initiate gesture so that gestures by people other than the person who performed the initiate gesture are ignored during the gesture session. The gesture session may last until the determine module 142 detects the end gesture from the person who performed the initiate gesture or until a preset inactivity time (e.g., an inactivity time specified in the settings 134) has passed since a last command was received from the person. When the end gesture is detected or the preset inactivity time has passed, the gesture controller 102 may remove the menu from the display device 110 and wait for detection of a new occurrence of the initiate gesture.
The end gesture may be the same gesture as the initiate gesture or may be a different gesture than the initiate gesture. For example, the initiate gesture specified in the settings 134 may include the person moving one or both hands towards and away from the display device 110. The end gesture specified in the settings 134 may include the person bowing towards and away from the display device with the persons arms folded. Other preset gestures or user defined gestures may be chosen as the initiate gesture or the end gesture.
The navigation gesture may be used to navigate a set of user selectable options, such as a menu. For example, in response to the navigation gesture, the gesture controller 102 may cause movement of an indication that shows which option of the menu is currently selected. An unselected option may be slightly transparent when not selected. An option that is highlighted and slightly transparent may indicate that the option can be selected by the person (e.g., by performing the selection gesture). An option that is highlighted and opaque may have been selected by the person performing the selection gesture. For example, the navigation gesture may be performed by the person moving one or both arms right to left to move the highlight from a first option to a second option to the left of the first option or to the rightmost option when the highlight is on the leftmost option. The navigation gesture may be performed by the person moving one or both arms left to right to move the highlight from a first option to a second option to the right of the first option or to the leftmost option when the highlight is on the rightmost option. As another example, the options of the menu may be presented in a circular pattern on the display device. The navigation gesture may be performed using a circular motion, either clockwise or counterclockwise, to move the highlight. Other preset gestures or user defined gestures may be chosen as the navigation gesture.
The selection gesture may be a gesture that indicates selection of a highlighted option. For example, the selection gesture indicated in the settings 134 may be performed by the person moving one or both open hands towards and away from the display device 110. Other preset gestures or user defined gestures may be chosen as the selection gesture.
When the processor 128 running the determine module 142 detects the initiate gesture, the processor 128 may use the menu module 144 to present the menu to the display device 110. The menu may include options selectable by the person. The options may include symbols, icons, text, video clips (i.e., animated icons), or combinations thereof. The video clips may be looped. An option may be presented in a manner that indicates to the person what the option does or represents. The menu option may also indicate a particular gesture that can be performed to select the option without using the navigate gestures to navigate the menu. For example, a particular option to present a submenu for devices other than the media device 108 and the display device 110 that are controllable via the gesture controller 102 may include a title of “Other Devices.” The particular menu option may also include a video clip of a person clapping, may include the text “clap to select,” or both to indicate that that a submenu for other devices will be displayed on the display device 110 when the option is selected using the navigation gesture and the selection gesture, or when the user performs the gesture of clapping.
When the person selects an option associated with a submenu (e.g., via a gesture), the processor 128 running the determine module 142 may use the menu module 144 to present the submenu. When the person selects an option associated with a command (e.g., via a gesture), the processor 128 may use the send module 146 to send a command or commands to an appropriate device or devices, such as one of the devices 106-120. For each command that is to be sent in response to the selection gesture, the processor 128 executing the send module 146 may access the device information 136 to determine which interface of the interfaces 130 to use to communicate with the appropriate device and may access the drivers 138 to create the appropriate command for the appropriate device. The processor 128 may send the created command to the appropriate device via the appropriate interface of the interfaces 130.
In some embodiments, the gesture controller 102 may be part of another device. For example, the gesture controller 102 may be a component of the media device 108, the display device 110, or the computer system 112. In some embodiments, the functionality of the menu module 144 may be present in and performed by another device (e.g., the media device 108, the display device 110, or the computer system 112). For example, when the processor 128 running the determine module 142 detects a particular gesture, an indication of the gesture may be sent to the media device 108. A processor of the media device 108 may execute instructions similar to the instructions of the menu module 144 that utilize the indication of the gesture to send appropriate display information (e.g., a submenu) to the display device 110.
FIG. 2 depicts an embodiment of a menu 200 sent to a display device 110 for device control based on gestures. The menu 200 may be sent to the display device 110 by a gesture controller, such as the gesture controller 102 depicted in FIG. 1. The menu 200 may be a top menu that is presented in response to a person in range of a gesture camera (e.g., the gesture camera 122 of FIG. 1) performing an initiate gesture. The menu 200 may include a plurality of icons associated with user selectable options, such as a volume icon 202, a mute icon 204, a channel icon 206, a play icon 208, and a devices icon 210. As depicted in FIG. 2, the channel icon 206 is highlighted, as indicated by a highlight box 212 around the channel icon 206. A user may move the highlight box 212 to the left or right by performing an appropriate navigate gesture. The user may select one of the icons 202-210 by highlighting the icon using the appropriate navigation gesture and by performing a select gesture. Some or all of the icons 202-210 may be associated with gestures that enable the user to quickly select particular icons. For example, after performing the initiate gesture, the person may perform a gesture of placing the person's hands against the person's ears to select the volume icon 202 or perform a gesture of placing the person's hands in front of the person's mouth to select the mute icon 204.
Selection of an icon 202-210 may result in presentation of a new menu. For example, when the person selects the volume icon 202, a submenu may be presented that includes additional icons, indications of gestures, or both that enable the person to increase the volume associated with the display device 110, decrease the volume associated with the display device 110, or end the gesture session when the volume is at a desired level. Selection of the channel icon 206 may present a submenu that includes additional icons, indications of gestures, or both to that enable the person to increase the channel number, decrease the channel number, or end the gesture session. Selection of the play icon 208 may present a list of devices that are available to play media content and an option to end the gesture session. When the person selects a particular device capable of playing media content or the particular device is the only device capable of playing media content, a menu that includes additional icons, indications of gestures, or both that enables the person to control the particular device and end the gesture session may be displayed. For example, controls for the particular device may include, but are not limited to, functions such as play, pause, record, fast forward, and rewind. Selection of the devices icon 210 may present a list of available devices, a list of available applications (e.g., a photo application that presents a slide show of photographs to the display device 110), an option to end the gesture session, or combinations thereof. Selection of a particular available device may present a submenu that includes additional icons, indications of gestures, or both that enable the person to control the particular available device and end the gesture session. Selection of a particular application may cause the application to run.
Selection of an icon 202-210 may result in at least one command being sent to one or more devices. For example, in response to selection of the mute icon 204 a gesture controller may send a command to an audio device associated with the display device 110 to mute the audio device when the audio device is not muted or to resume providing audio for the audio device when the device is muted.
Referring to FIG. 3, a flow chart of a first particular embodiment of a method for electronic device control based on gestures is shown. The method may be performed, for example, by the system depicted in FIG. 1.
At 302, an initiate gesture may be detected at a gesture controller in response to initial three dimensional (3D) image data obtained from a gesture camera. The initiate gesture may be a general initiate gesture or a specific gesture for a particular electronic device. The general initiate gesture may result in presentation of a menu (e.g., the menu 200 of FIG. 2) that that has options that can be selected to present submenus, to send commands, or both. The specific gesture for the particular device may be selected to present submenus, commands, or both for the particular device.
A user of the gesture controller may define a specific gesture for a particular device using a set-up feature of the gesture controller. For example, the user may access the set-up feature and select a particular gesture that will be associated with activating a menu associated with a security system. The particular gesture may be chosen from a set of pre-defined gestures or the particular gesture may be performed by the user in front of the gesture camera to establish a new gesture. The user may define one or more other gestures for the security system or other devices, for the initiate gestures, for navigation gestures, for end gestures, for selection gestures, or other types of gestures. The set-up feature may be accessed by various ways. For example, the set-up feature may be accessed by using an activation sequence on the gesture controller (e.g., pressing a set-up button of the gesture controller), by using a remote control device, by using an access device coupled to the gesture controller (e.g., a computer system or a set-top box device), by using gestures to access the set-up feature through the gesture controller, or combinations thereof.
The gesture controller may identify one or more characteristics of a first person performing the initiate gesture from the initial 3D image data to allow the first person to be tracked, at 304. The one or more characteristics may include, but are not limited to, distinct features of the first person (e.g., hair length, hair color, height, facial characteristics, visible tattoos, etc.), clothing or jewelry worn by the first person, location of the first person in a room, or combinations thereof. The location characteristic may be updated when the first person changes location in the room.
At 306, gestures of a second person within range of the gesture camera other than the first person may be ignored after detecting the initiate gesture. For example, gestures performed by the second person may be ignored until the gesture controller detects an end gesture from the first person. In another example, gestures performed by the second person may be ignored until passage of a preset inactivity time from a previous gesture of the first person detected by the gesture controller. The inactivity time may be a parameter that the user can set via the set-up feature of the gesture controller. The end gesture may be the same as the initiate gesture or the end gesture may be a different gesture. When the end gesture is received from the first person, or when passage of the preset inactivity time occurs, received gestures may be ignored until the gesture controller detects another initiate gesture from the person or from another person.
At 308, a menu may be sent from the gesture controller to a display device. The menu may include selectable options to control at least one electronic device. The menu may be sent in response to detection of the initiate gesture by the first person. Selection of the selectable options may result in presentation of one or more submenus or may result in generation of one or more commands to one or more devices.
At 310, a first user gesture may be detected at the gesture controller in response to 3D image data obtained from the gesture camera. The first user gesture may be a gesture made by the first person. A command for a particular device may be determined at the gesture controller based on the first user gesture and based on the menu, at 312.
At 314, the gesture controller may determine that the first person is authorized to implement the at least one command for the particular device. Some commands (e.g., increasing or decreasing volume, muting an electronic device, adjusting lighting, etc.) may be made by any person. Other commands (e.g., changing channels, controlling a telephone, responding to an alarm condition of a security system, etc.) may be limited to a selected person or selected people. Restrictions for certain devices may be time dependent. For example, changing channels of a television may be unrestricted during a particular time slot (e.g., from 8:00 am to 6:00 pm) and may be restricted to one or more particular adults at other times. The authorization may be based on the one or more identified characteristics of the first person, the first person may be prompted to supply additional information, or both. The additional information may include, but is not limited to, a username, a password, a voice sample, fingerprint input, other identification credentials, or combinations thereof. Time dependencies and types of additional information needed for identification may be specified using the set-up feature of the gesture controller.
A decision based on the determination of whether the first person is authorized to implement the at least one command may be made, at 316. When the determination is that the first person is not authorized to implement the command, a message may be sent to the display device, at 318. The message may inform the first person that control of the particular device by the first person has been denied.
In a particular embodiment, other actions may be taken when the determination is that the first person is not authorized to implement the command. For example, user specified settings (entered via the set-up feature of the gesture controller) may determine what happens when an attempt to command an electronic device fails. The settings may include, but are not limited to, a number of attempts to access a device before access to the device is locked out for a user specified time, sending a message (e.g., a text message, an e-mail, or a phone message) to a designated person or people when a specified number of attempts fail, specific content of messages sent to the display device when attempts fail, and combinations thereof.
When the determination is that the first person is authorized to implement the command, the command may be sent from the gesture controller to the particular device, at 320. The method may end, at 322.
Referring to FIG. 4, a flow chart of a second particular embodiment of a method for electronic device control based on gestures is shown. The method may be performed, for example, by the system depicted in FIG. 1.
At 402, an indication of activation of a particular electronic device may be received by a gesture controller. The gesture controller may send a menu to a display device, at 404. The menu may include selectable options to control at least the particular electronic device. The menu may also include selectable options to control other electronic devices. For example, the menu may include an option to mute, pause, or stop one or more other electronic devices that are currently active and may include options to control the particular electronic device.
The menu may be specific to the particular electronic device. For example, the particular electronic device may be a telephone that is activated in response to the telephone receiving an incoming call. When the telephone is a mobile communication device, the gesture controller may receive an activation notice regarding the incoming call from a computer system, a set-top box device, a telephone base station, or other device that detects the presence of the mobile communication device near to the display device (e.g., within the same room as the display device). The gesture controller may receive caller identification information for the incoming call. The menu provided by the gesture controller may include the caller identification information and may provide several options. For example, the options may include, but are not limited to, an option to send the incoming call to voicemail, an option to pause or mute one or more other devices that are currently active and allow the call to ring to the telephone, an option to allow the call to ring to the telephone without changing a status of other active devices, and an option to terminate the call. The options may be presented as icons on the display device. A person using the menu may navigate the menu using navigation gestures (e.g., by moving an arm left or right to move a selection indicator from one icon to another icon) and may select a particular icon by performing a selection gesture (e.g., moving a hand or both hands towards and away from the display device). The icons may be animated or may show still images that suggest one or more gestures. The icons may represent specific gestures that the person can perform to activate particular icons. For example, the icon for terminating the call may show a representation of a user passing a hand in front of the user's throat. In this example, when the person passes a hand in front of his or her throat, the call may be terminated without the person having to navigate to the icon for terminating the call.
As another example, the particular electronic device may be a controller of a security system that is activated (e.g., because a window or a door has been opened). The controller of the security system may send information regarding an alarm to the gesture controller. The gesture controller may send a menu to the display device that presents the information regarding the alarm and options. The options may include, but are not limited to, an option to immediately notify one or more authorities (e.g., a security company, the police, or both) and an option to delay notifying the one or more authorities for a period of time (e.g., 5 minutes). When the person chooses the option to delay, the display screen may show a countdown timer for remaining time, the option to immediately notify the one or more authorities, and an option to resume normal operation of the security system. Should the countdown time reach zero, the one or more authorities may be automatically notified of a potential problem. An attempt by a person other than an authorized individual to select the option to delay or the option to resume normal operation of the security system may result in automatic notification of the one or more authorities of a potential problem.
At 406, a first user gesture from a first person may be detected at the gesture controller in response to three dimensional (3D) image data obtained from a gesture camera. At least one command for the particular device may be determined at the gesture controller based on the first user gesture and the based on the menu, at 408.
At 410, the gesture controller may determine that the first person is authorized to implement the command for the particular device. The authorization may be based on the 3D image data, additional information provided by the first person, or both. The additional information may include, but is not limited to, a username, a password, a voice sample, fingerprint input, other identification credentials, or combinations thereof.
A decision based on the determination of whether the first person is authorized to implement the command may be made, at 412. When the determination is that the first person is not authorized to implement the command, a message may be sent to the display device, at 414. The message may inform the first person that control of the particular device by the first person has been denied. When the determination is that the first person is authorized to implement the command, the command may be sent from the gesture controller to the particular device, at 416. The method may end, at 418.
Various embodiments disclosed herein enable electronic devices within a residence to be controlled based on gestures made by a user. The gestures may enable control of one or more devices without the need for the user to hold, wear, or be in contact with a sensor or a remote control device. Gestures of a user may be detected by a three dimensional (3D) image device. Data from the 3D image device may be analyzed by a gesture controller to determine whether gestures made by the user should be ignored, should result in sending a menu to a display device, should result in navigation of the menu, should result in selection of menu options, or should result in the gesture controller sending at least one command to one or more devices. The gesture controller may replace a remote control device, may be used when the user does not desire to use or cannot easily access the remote control device, or may be used when the user wants to control a device that is able to be controlled using the gesture controller but not the remote control device.
