Definitions
- the present application relates to the field of remote control devices for television and video devices. More particularly, the described embodiments relate to a remote control device that has two interface panels on opposite sides of the device, where the remote uses an orientation sensor to ignore signals from certain inputs based upon the orientation of the remote control.
- FIG. 1 is a perspective drawing of a first embodiment of the present invention showing a first face in the upward position.
- FIG. 2 is a perspective drawing of the first embodiment of the present invention showing a second face in the upward position.
- FIG. 3 is a schematic view of the major components of an embodiment of the present invention.
- FIG. 4 is a perspective drawing of a second embodiment of the present invention showing a virtual keypad on its second face.
- FIG. 5 is a perspective drawing of the second embodiment of the present invention showing an electronic programming guide on its second face.
- FIG. 6 is a perspective drawing of the second embodiment of the present invention showing an interactive, network based application running on its second face.
- FIG. 7 is a flow chart showing the process used to implement an exemplary embodiment of the present invention.
- FIG. 1 shows one embodiment of a remote control 10 with a first face 20 in an upright position.
- This first face 20 contains numerous buttons 30 that are used to interface with a television or other video device 5 , which is shown significantly smaller than the remote 10 in FIG. 1 to indicate that the device 5 is located remotely from the remote 10 .
- the video device 5 may be a television, a video display monitor, a projection monitor, or some other device capable of displaying a video signal.
- the remote control 10 may control the video device 5 directly. Alternatively, the remote control 10 may control a device that provides a video signal or source to the television or monitor, which in turn displays the video signal.
- the remote control 10 may control a cable or satellite television set-top-box, a streaming video network device as a Roku DVP device from Roku (Saratoga, Calif.) or an Apple TV device from Apple Inc. (Cupertino, Calif.), or even a media computer.
- a streaming video network device as a Roku DVP device from Roku (Saratoga, Calif.) or an Apple TV device from Apple Inc. (Cupertino, Calif.), or even a media computer.
- the devices that are controlled by the remote control are referred to as a television or a video or display device.
- Such references should be read to include devices containing the actual display technology as well as devices that provide video signals to such devices.
- the buttons 30 may include power, source, volume, channel up/down, a ten-key pad, and other standard buttons 30 found in typical remote controls of the prior art.
- the buttons 30 shown in FIG. 1 also includes a menu button, and a four-way direction pad and selection button that allows the remote control to control a GUI interface or menu system on the television 5 .
- the remote 10 also has a second face 50 that is located on the side of the remote 10 that is opposite the first face 20 .
- the second face 50 also contains a plurality of buttons 60 that send signals to the television or video device 5 .
- the second face 50 contains a plurality of letter buttons in a QWERTY configuration to allow the user to input text to the television 5 .
- the keyboard layout shown in FIG. 2 is merely exemplary, and other arrangements of keys for the reverse face 50 would be within the scope of the present invention.
- the QWERTY keyboard layout could be retained for letters, with the numeric keys being arranged in a 10-key layout to the right or left of the letter keys.
- some keys could be located on both the top face 20 and the bottom face 50 of the keyboard, such as the four-way direction pad and selection button for interacting with a GUI on the television 5 .
- buttons 30 , 60 both faces 20 , 50 are shown with a plurality of buttons 30 , 60 .
- the term button indicates an element on the face 20 , 50 that is touched or pushed by a user to provide input to the remote.
- the buttons 30 , 60 shown in FIGS. 1 and 2 are physical push buttons that move physically with respect to faces 20 , 50 when pushed. Most push buttons 30 , 60 provide input using a simple switch mechanism where a switch is opened or closed by the physical translation of the button with respect to the device on which the button is mounted. Other types of buttons are possible, including buttons where pressure on or contact with the button is noted without requiring any physical movement of the button.
- the remote contains standard buttons on face 20 , and a fully QWERTY keyboard on face 50 . If the user were merely interested in controlling source, channel, or volume of the television set 5 , they would hold the remote so that face 20 was upwards and then use the buttons 30 found on this face 20 . When the display 5 showed an interface to a user that required textual input, the user would simply turn the remote 10 over so that face 50 was upwards. In this configuration, as shown in FIG.
- the letter keys 60 would be facing upwards and the user could enter any text necessary simply by pressing the appropriate button on the remote 60 .
- Other solutions to text input in televisions and similar displays 50 require interaction with an onscreen keyboard, multiple button pushes of numeric buttons on a ten-key pad (with multiple letters sharing a single key for input), the use of a slide-out keyboard tray, or the use of a keyboard that is separate from the remote.
- the solution shown in FIGS. 1 and 2 allows the remote 10 to a have separate key for each letter, eliminates the need for a separate keyboard, and reduces the size of the remote by grouping related keys on opposite faces of the same remote without the need for a slide-out component.
- the remote 10 While holding the remote 10 with either face 20 or face 50 in the upwards position, it is possible, and perhaps likely, that the user will accidently press a button found on the downward facing face 50 , 20 of the remote. To prevent these accidental button pushes from registering as actual commands to the display/television 5 , the remote 10 incorporates one or more position or orientation sensors, such as accelerometers or gyroscopic sensors, to detect which face 20 , 50 is currently upwards.
- One accelerometer that could be used to provide the functionality is model number LIS331DLH, a 3-axis smart motion sensor from STMicroelectronics (Geneva, Switzerland).
- An example gyroscopic sensor would be a microelectromechanical system (or “MEMS”) gyroscope such as the L3G4200DH digital gyroscope also sold by STMicroelectronics.
- MEMS microelectromechanical system
- the combination of a 3-axis accelerometer and gyroscope would allow the remote 10 to have more detailed knowledge of its current position and orientation than either sensor acting alone. While such knowledge would be useful in programming advance features for the remote (such as game play or tilt interaction), the minimum sensor configuration necessary to implement the upward/downward determination needed to disable certain keys is a single axis accelerometer.
- the one or more accelerometer or gyroscopic sensors used in the remote 10 will be referred to collectively as the orientation sensor.
- the orientation sensor the one or more accelerometer or gyroscopic sensors used in the remote 10 will be referred to collectively as the orientation sensor.
- future improvements made to art of orientation sensors could be applied to the remote 10 .
- the remote 10 With the aid of its orientation sensor(s), the remote 10 is able to identify when face 20 is upwards facing, and therefore deactivate the buttons 60 found on the reverse face 50 of the remote. In other words, commands issued from the buttons 60 are blocked (not sent by the remote) when face 20 is upwards facing. Similarly, when the remote 10 is held with face 50 upright as is shown in FIG. 2 , this position would be sensed by the orientation sensor and the remote 10 would deactivate the buttons 30 on face 20 .
- One way to block or deactivate the buttons is to simply power down the buttons 30 , 60 that are currently being blocked.
- the remote 10 would also include corner stand elements 70 on one or both of the faces 20 , 50 .
- These elements 70 shown in FIGS. 1 and 2 at all four corners of both face 20 and face 50 , allow the remote 10 to rest on a table or other flat surface without impacting the buttons 30 or 60 located on the downward facing side 20 , 50 . Instead, the remote 10 will rest on the four corner stand elements 70 , which extend above their respective faces 20 , 50 so as to be taller than any of the active buttons 30 , 60 on that face 20 , 50 .
- the corner elements 70 will not prevent accidental pressing of the buttons 30 , 60 on the downward face 20 , 50 when the remote 10 is held in the hand, nor will it be of assistance if the remote 10 is placed on an uneven surface.
- the corner elements 70 could both aid in reassuring users, and to provide a more stable rest for the remote 10 , such as when the user is using the QWERTY keyboard 60 when the remote 10 is resting on a table.
- the corner elements 70 are found on all four corners of at least one of the faces 20 , 50 , and preferably are formed of generally resilient material such as rubber. In other embodiments, no corner elements 70 are used on either surface 20 , 50 of the remote.
- FIG. 3 schematically shows the elements of one embodiment of a remote control 100 implementing the present invention.
- the remote 100 includes one or more orientation sensors 110 that determine the orientation of the remote 100 , such as a single or multi-axis accelerometer or gyroscope as described above.
- the orientation sensor 110 is monitored by a processor 120 to manage inputs to the remote 100 .
- the inputs are received through input interface 130 .
- the inputs will be received by a user interacting with a touch-based interface on the surface of the remote 100 .
- the input interface 130 may receive input signals from one or more keys 140 , such as the buttons 30 , 60 shown in FIGS. 1 and 2 .
- the input processor 130 could receive touch-based input through a LCD touchscreen 150 .
- a touchscreen 150 on the remote 100 could be advantageous as the processor 120 could provide output useful to the user on the touchscreen's display, or could even implement a virtual key arrangement on the display, as shown below in connection with FIGS. 4-5 .
- Other types of touch input could be implemented on remote 100 , such as a touchpad/trackpad, a rotating ball, a pointing stick, etc. These inputs could be used to select items on the remote screen or move a cursor on the controlled display 190 .
- a touchpad could be used to allow a user to provide direct input into the remote 100 . For instance, gestures made by tracing a finger over the touchpad could be interpreted by the remote 100 as commands to the remote 100 or television 190 . Alternatively, a user could draw letters or numbers on the touchpad, allowing the remote to receive alphanumeric characters without requiring a physical or virtual keyboard. Touchpads, trackpads, and touchscreens can all be considered as types of touch-sensitive surfaces.
- FIG. 3 a single input interface is shown connecting with both physical keys 140 and a touchscreen 150 . In most implementations, however, each type of input would be associated with a separate input controller specialized for that type of input.
- a single input processor 130 is used in FIG. 3 for ease in understanding this embodiment of the invention.
- the physical inputs 140 , 150 are located on at least two faces or sides of the remote 100 .
- the processor 120 is able to use the position of the remote 100 as determined by the orientation sensor 110 in order to selectively activate and deactivate some of the inputs 140 , 150 .
- the orientation sensor 110 would identify to the processor whether the first face 20 or the second face 50 is currently in the upright position. Based on this information, the processor can selectively activate and deactivate the first set of the keys 30 or the second of keys 60 .
- the processor 120 forwards that input choice to a transceiver device 170 for communication with a remote television or display, such as television 190 .
- the transceiver 170 could incorporate an infrared transmitter, transmitting infrared light signals to the remote device 190 .
- the transceiver 170 could send radio frequency signals to the device in the same manner as known RF remote controls. These control signals can be formatted according to a proprietary signaling protocol, or according to standard radio frequency signaling protocols such as Bluetooth. Because more and more televisions and displays are themselves network connected using WiFi protocols (using IEEE 802.11 networking standards), the transceiver 170 could also communicate with the television 190 using those same WiFi protocols.
- the remote 100 could engage in complex, two-way communications with the television, so as to add additional functionality to the remote.
- the remote 100 may even take advantage of the WiFi transceiver 170 to establish a separate network connection to the Internet, allowing direct wide area network communications from the remote 100 without passing such communications through the television 190 .
- Such Internet connections could be used to maintain and update the remote, could allow for interactive communications with the Internet by the user using only the remote, and could even allow for the downloading of separate “Apps” to increase the functionality of the remote.
- the remote includes an infrared transmitter, a radio frequency transmitter (using standard RF remote frequencies), and a WiFi interface.
- the orientation sensor 110 can be used to deactivate those touch inputs 140 , 150 that are downward facing at any particular moment.
- the embodiment shown in FIG. 3 also utilizes a clock 180 to implement a time-out mechanism. If the remote 100 , for instance, is lodged between cushions in a chair, unintended touch inputs at 140 , 150 might be registered by the remote 100 even though those inputs 140 , 150 are in a generally upright position.
- the processor uses the clock 180 to determine whether the orientation sensor 110 has recorded any significant movement in the remote 100 over a preset time interval.
- the processor 130 can either ignore these inputs or, if so desired, power down the remote 100 to avoid battery drain issues.
- the remote 100 will power down only after some indication is provided to the user that the remote 100 will soon turn itself off. This signal may be visibly presented on a display embedded in the remote (such as touchscreen 150 ), or audibly presented through a tone or other warning noise that is output through a speaker or vibration device (not shown). The user could then avoid the power down event by discontinuing the repeating input or by moving the remote 100 so that movement is sensed by orientation sensor 110 .
- Television 190 receives inputs from the remote 100 and transmits data and instructions to the remote through its own infrared/radio/WiFi transceiver 192 .
- the television uses this input to control what is shown on its display 194 , which may be a cathode ray tube, LCD, plasma display, projection display, or some other display technology.
- the inputs from the remote 100 are analyzed by processor 196 operating under instructions of programming stored in a memory device 198 .
- the instructions that control the processors 120 , 196 of the remote 100 and television 190 are stored in memory devices 160 , 198 .
- These memories 160 , 198 may comprise tangible, non-transitory, updateable memory devices such as flash memory, or could be stored in a less flexible, read only memory device.
- both memories 160 , 196 constitute solid state, non-transitory flash memory devices.
- the instructions may be executed directly from the non-transitory memory, or may be first loaded into RAM for faster processing.
- the processors 120 , 196 may take the form of general purpose CPUs, such as those provided by Intel Corporation (Santa Clara, Calif.), Advanced Micro Devices, Inc. (Sunnyvale, Calif.), or ARM Holdings (Cambridge, England).
- processor and instructions could be combined in the form of a programmable logic device specially programmed to perform the functions of the remote 100 or the television 190 .
- a programmable logic device would contain both the processor 120 , 196 and the memory 160 , 198 containing the instructions for the processor 120 , 196 .
- FIG. 4 Another embodiment of the present invention is the remote control 200 shown in FIG. 4 .
- the entire QWERTY keyboard of FIG. 2 is replaced with a single display touchscreen 210 .
- This touchscreen could use a variety of touchscreen technologies known in the prior art, including capacitive LCD touchscreen technology as is commonly used on cellular smart phones.
- the touchscreen 210 displays an image of the QWERTY keypad. A user can input any letter on the keypad simply by touching on the desired letter.
- the remote 200 is held with the top face upright, the touchscreen 210 on the bottom of the remote 200 remains inactive.
- the remote 200 is oriented so that the bottom face is generally upright. In this position, the touchscreen 210 is active.
- buttons 30 are shown in FIG. 1
- almost all television remotes at the present time include many additional buttons as well.
- buttons are frequently found on remote controls dedicated to selecting different source inputs, for picture-in-picture capabilities, for electronic program guide (EPG) interaction, for close captioning and subtitles, and for DVR capabilities (such as play, pause, reverse, fast forward).
- EPG electronic program guide
- DVR digital video recorder
- the “top” face could present the user with a simplified interface using only the most frequently used buttons, such as shown in FIG. 1 .
- the touchscreen could display all of the other buttons that may be needed only occasionally, either on a single screen or on multiple pages.
- buttons When using a remote with a touchscreen 210 , the user can page through multiple screens of potential buttons as needed.
- the touchscreen has a first location 212 that, when pressed, will change the display of the touchscreen to show DVR related buttons.
- a second location 214 may convert the touchscreen to a page with advanced buttons, such as picture-in-picture buttons, or advanced color or audio modification buttons.
- a third location 216 initiates an electronic program guide, such as the EPG interface 220 shown in FIG. 5 .
- the EPG interface has a standard grid configuration, with time changing along a left-to-right or x-axis and channels changing on an up-and-down or y-axis. Within the grid, the programming for the displayed channels at the displayed times is indicated.
- a currently selected portion of the grid is darkened at location 222 . This selected portion 222 indicates which programming is featured in the detail location 224 of the EPG interface 220 . In this case, channel 4 at 8:00 is selected. Channel 4 shows NFL football at that time, so the detail area 224 provides information about that programming.
- This detailed information 224 may be a textual description, a video preview, or if the program is currently playing, a live view of the football game.
- the television or display device provides the video preview by streaming video to the remote control for display within the EPG 220 . Due to the size of the video displayed on the remote, only a low-resolution video stream is required for display on the remote 200 .
- the information for the EPG 220 is received by the remote control over the WiFi or radio frequency interface 170 .
- the television or display that is controlled by the remote 200 also transmits data to the remote 200 .
- This data may be raw EPG data, where programming within the memory 160 of the remote 200 instructs the processor 120 how to construct the EPG interface 220 based upon this raw data.

FIG. 1 shows one embodiment of aremote control 10 with afirst face 20 in an upright position. Thisfirst face 20 containsnumerous buttons 30 that are used to interface with a television orother video device 5, which is shown significantly smaller than the remote 10 inFIG. 1 to indicate that thedevice 5 is located remotely from the remote 10. Thevideo device 5 may be a television, a video display monitor, a projection monitor, or some other device capable of displaying a video signal. Theremote control 10 may control thevideo device 5 directly. Alternatively, theremote control 10 may control a device that provides a video signal or source to the television or monitor, which in turn displays the video signal. For example, theremote control 10 may control a cable or satellite television set-top-box, a streaming video network device as a Roku DVP device from Roku (Saratoga, Calif.) or an Apple TV device from Apple Inc. (Cupertino, Calif.), or even a media computer. For purposes of this disclosure, the devices that are controlled by the remote control are referred to as a television or a video or display device. Such references should be read to include devices containing the actual display technology as well as devices that provide video signals to such devices. - The
buttons 30 may include power, source, volume, channel up/down, a ten-key pad, and otherstandard buttons 30 found in typical remote controls of the prior art. Thebuttons 30 shown inFIG. 1 also includes a menu button, and a four-way direction pad and selection button that allows the remote control to control a GUI interface or menu system on thetelevision 5. - As shown in
FIG. 2 , the remote 10 also has asecond face 50 that is located on the side of the remote 10 that is opposite thefirst face 20. Like thefirst face 20, thesecond face 50 also contains a plurality ofbuttons 60 that send signals to the television orvideo device 5. In the embodiment shown inFIG. 2 , thesecond face 50 contains a plurality of letter buttons in a QWERTY configuration to allow the user to input text to thetelevision 5. The keyboard layout shown inFIG. 2 is merely exemplary, and other arrangements of keys for thereverse face 50 would be within the scope of the present invention. For instance, the QWERTY keyboard layout could be retained for letters, with the numeric keys being arranged in a 10-key layout to the right or left of the letter keys. In addition, some keys could be located on both thetop face 20 and thebottom face 50 of the keyboard, such as the four-way direction pad and selection button for interacting with a GUI on thetelevision 5. - In
FIGS. 1 and 2 , both faces 20, 50 are shown with a plurality ofbuttons face buttons FIGS. 1 and 2 are physical push buttons that move physically with respect to faces 20, 50 when pushed.Most push buttons - The advantage of having a remote with
opposite faces embodiment 10 shown inFIGS. 1 and 2 , the remote contains standard buttons onface 20, and a fully QWERTY keyboard onface 50. If the user were merely interested in controlling source, channel, or volume of thetelevision set 5, they would hold the remote so thatface 20 was upwards and then use thebuttons 30 found on thisface 20. When thedisplay 5 showed an interface to a user that required textual input, the user would simply turn the remote 10 over so thatface 50 was upwards. In this configuration, as shown inFIG. 2 , theletter keys 60 would be facing upwards and the user could enter any text necessary simply by pressing the appropriate button on the remote 60. Other solutions to text input in televisions andsimilar displays 50 require interaction with an onscreen keyboard, multiple button pushes of numeric buttons on a ten-key pad (with multiple letters sharing a single key for input), the use of a slide-out keyboard tray, or the use of a keyboard that is separate from the remote. The solution shown inFIGS. 1 and 2 allows the remote 10 to a have separate key for each letter, eliminates the need for a separate keyboard, and reduces the size of the remote by grouping related keys on opposite faces of the same remote without the need for a slide-out component. - While holding the remote 10 with either
face 20 orface 50 in the upwards position, it is possible, and perhaps likely, that the user will accidently press a button found on the downward facingface television 5, the remote 10 incorporates one or more position or orientation sensors, such as accelerometers or gyroscopic sensors, to detect which face 20, 50 is currently upwards. One accelerometer that could be used to provide the functionality is model number LIS331DLH, a 3-axis smart motion sensor from STMicroelectronics (Geneva, Switzerland). An example gyroscopic sensor would be a microelectromechanical system (or “MEMS”) gyroscope such as the L3G4200DH digital gyroscope also sold by STMicroelectronics. The combination of a 3-axis accelerometer and gyroscope would allow the remote 10 to have more detailed knowledge of its current position and orientation than either sensor acting alone. While such knowledge would be useful in programming advance features for the remote (such as game play or tilt interaction), the minimum sensor configuration necessary to implement the upward/downward determination needed to disable certain keys is a single axis accelerometer. For ease in description, the one or more accelerometer or gyroscopic sensors used in the remote 10 will be referred to collectively as the orientation sensor. In addition, one skilled in the art would appreciate that future improvements made to art of orientation sensors could be applied to the remote 10. - With the aid of its orientation sensor(s), the remote 10 is able to identify when
face 20 is upwards facing, and therefore deactivate thebuttons 60 found on thereverse face 50 of the remote. In other words, commands issued from thebuttons 60 are blocked (not sent by the remote) whenface 20 is upwards facing. Similarly, when the remote 10 is held withface 50 upright as is shown inFIG. 2 , this position would be sensed by the orientation sensor and the remote 10 would deactivate thebuttons 30 onface 20. One way to block or deactivate the buttons is to simply power down thebuttons - In one embodiment, the remote 10 would also include
corner stand elements 70 on one or both of thefaces elements 70, shown inFIGS. 1 and 2 at all four corners of bothface 20 andface 50, allow the remote 10 to rest on a table or other flat surface without impacting thebuttons side corner stand elements 70, which extend above theirrespective faces active buttons face corner elements 70 will not prevent accidental pressing of thebuttons downward face corner elements 70 could both aid in reassuring users, and to provide a more stable rest for the remote 10, such as when the user is using the QWERTYkeyboard 60 when the remote 10 is resting on a table. In one embodiment, thecorner elements 70 are found on all four corners of at least one of thefaces corner elements 70 are used on eithersurface -
FIG. 3 schematically shows the elements of one embodiment of aremote control 100 implementing the present invention. The remote 100 includes one ormore orientation sensors 110 that determine the orientation of the remote 100, such as a single or multi-axis accelerometer or gyroscope as described above. Theorientation sensor 110 is monitored by aprocessor 120 to manage inputs to the remote 100. In one embodiment, the inputs are received throughinput interface 130. In most cases, the inputs will be received by a user interacting with a touch-based interface on the surface of the remote 100. For example, theinput interface 130 may receive input signals from one ormore keys 140, such as thebuttons FIGS. 1 and 2 . In addition, theinput processor 130 could receive touch-based input through aLCD touchscreen 150. The implementation of atouchscreen 150 on the remote 100 could be advantageous as theprocessor 120 could provide output useful to the user on the touchscreen's display, or could even implement a virtual key arrangement on the display, as shown below in connection withFIGS. 4-5 . Other types of touch input could be implemented on remote 100, such as a touchpad/trackpad, a rotating ball, a pointing stick, etc. These inputs could be used to select items on the remote screen or move a cursor on the controlleddisplay 190. Furthermore, a touchpad could be used to allow a user to provide direct input into the remote 100. For instance, gestures made by tracing a finger over the touchpad could be interpreted by the remote 100 as commands to the remote 100 ortelevision 190. Alternatively, a user could draw letters or numbers on the touchpad, allowing the remote to receive alphanumeric characters without requiring a physical or virtual keyboard. Touchpads, trackpads, and touchscreens can all be considered as types of touch-sensitive surfaces. - In
FIG. 3 , a single input interface is shown connecting with bothphysical keys 140 and atouchscreen 150. In most implementations, however, each type of input would be associated with a separate input controller specialized for that type of input. Asingle input processor 130 is used inFIG. 3 for ease in understanding this embodiment of the invention. - The
physical inputs memory 160 on the remote 100, theprocessor 120 is able to use the position of the remote 100 as determined by theorientation sensor 110 in order to selectively activate and deactivate some of theinputs FIGS. 1 and 2 , theorientation sensor 110 would identify to the processor whether thefirst face 20 or thesecond face 50 is currently in the upright position. Based on this information, the processor can selectively activate and deactivate the first set of thekeys 30 or the second ofkeys 60. - When input is received by the
input interface 130 from anactive input mechanism processor 120 forwards that input choice to atransceiver device 170 for communication with a remote television or display, such astelevision 190. Thetransceiver 170 could incorporate an infrared transmitter, transmitting infrared light signals to theremote device 190. Alternatively, thetransceiver 170 could send radio frequency signals to the device in the same manner as known RF remote controls. These control signals can be formatted according to a proprietary signaling protocol, or according to standard radio frequency signaling protocols such as Bluetooth. Because more and more televisions and displays are themselves network connected using WiFi protocols (using IEEE 802.11 networking standards), thetransceiver 170 could also communicate with thetelevision 190 using those same WiFi protocols. By so doing, the remote 100 could engage in complex, two-way communications with the television, so as to add additional functionality to the remote. The remote 100 may even take advantage of theWiFi transceiver 170 to establish a separate network connection to the Internet, allowing direct wide area network communications from the remote 100 without passing such communications through thetelevision 190. Such Internet connections could be used to maintain and update the remote, could allow for interactive communications with the Internet by the user using only the remote, and could even allow for the downloading of separate “Apps” to increase the functionality of the remote. In one embodiment, the remote includes an infrared transmitter, a radio frequency transmitter (using standard RF remote frequencies), and a WiFi interface. This gives the remote 100 maximum flexibility in interacting with a variety of devices—direct control of the remote television or display can take place via IR or RF commands without the need for a WiFi router to manage a wireless network, while more complicated interactions can be accomplished over WiFi when that network is available. - Because the remote 100 has inputs on multiple surfaces, it is important to ensure that signals received from
inputs orientation sensor 110 can be used to deactivate thosetouch inputs FIG. 3 also utilizes aclock 180 to implement a time-out mechanism. If the remote 100, for instance, is lodged between cushions in a chair, unintended touch inputs at 140, 150 might be registered by the remote 100 even though thoseinputs clock 180 to determine whether theorientation sensor 110 has recorded any significant movement in the remote 100 over a preset time interval. If not, and theinput processor 130 has been signaling a repeating input at asingle key 140 or a single location on thetouchscreen 150, the processor can either ignore these inputs or, if so desired, power down the remote 100 to avoid battery drain issues. In one embodiment, the remote 100 will power down only after some indication is provided to the user that the remote 100 will soon turn itself off. This signal may be visibly presented on a display embedded in the remote (such as touchscreen 150), or audibly presented through a tone or other warning noise that is output through a speaker or vibration device (not shown). The user could then avoid the power down event by discontinuing the repeating input or by moving the remote 100 so that movement is sensed byorientation sensor 110. -
Television 190 receives inputs from the remote 100 and transmits data and instructions to the remote through its own infrared/radio/WiFi transceiver 192. The television uses this input to control what is shown on itsdisplay 194, which may be a cathode ray tube, LCD, plasma display, projection display, or some other display technology. The inputs from the remote 100 are analyzed byprocessor 196 operating under instructions of programming stored in amemory device 198. - The instructions that control the
processors television 190 are stored inmemory devices memories memories processors television 190. In effect, a programmable logic device would contain both theprocessor memory processor - Another embodiment of the present invention is the
remote control 200 shown inFIG. 4 . In this figure, the entire QWERTY keyboard ofFIG. 2 is replaced with asingle display touchscreen 210. This touchscreen could use a variety of touchscreen technologies known in the prior art, including capacitive LCD touchscreen technology as is commonly used on cellular smart phones. InFIG. 4 , thetouchscreen 210 displays an image of the QWERTY keypad. A user can input any letter on the keypad simply by touching on the desired letter. When the remote 200 is held with the top face upright, thetouchscreen 210 on the bottom of the remote 200 remains inactive. When the user desires to use thetouchscreen input 210, the remote 200 is oriented so that the bottom face is generally upright. In this position, thetouchscreen 210 is active. - One of the primary benefits of the use of a
touchscreen 210 is that the image shown on thetouchscreen 210 can change during use of the remote 200. For example, while commonly usedremote control buttons 30 are shown inFIG. 1 , almost all television remotes at the present time include many additional buttons as well. For instance, buttons are frequently found on remote controls dedicated to selecting different source inputs, for picture-in-picture capabilities, for electronic program guide (EPG) interaction, for close captioning and subtitles, and for DVR capabilities (such as play, pause, reverse, fast forward). With a touchscreen found on a “bottom” face of a remote, the “top” face could present the user with a simplified interface using only the most frequently used buttons, such as shown inFIG. 1 . The touchscreen could display all of the other buttons that may be needed only occasionally, either on a single screen or on multiple pages. - When using a remote with a
touchscreen 210, the user can page through multiple screens of potential buttons as needed. InFIG. 4 , the touchscreen has afirst location 212 that, when pressed, will change the display of the touchscreen to show DVR related buttons. Asecond location 214 may convert the touchscreen to a page with advanced buttons, such as picture-in-picture buttons, or advanced color or audio modification buttons. - A
third location 216 initiates an electronic program guide, such as theEPG interface 220 shown inFIG. 5 . The EPG interface has a standard grid configuration, with time changing along a left-to-right or x-axis and channels changing on an up-and-down or y-axis. Within the grid, the programming for the displayed channels at the displayed times is indicated. InEPG interface 220, a currently selected portion of the grid is darkened atlocation 222. This selectedportion 222 indicates which programming is featured in thedetail location 224 of theEPG interface 220. In this case, channel 4 at 8:00 is selected. Channel 4 shows NFL football at that time, so thedetail area 224 provides information about that programming. Thisdetailed information 224 may be a textual description, a video preview, or if the program is currently playing, a live view of the football game. In one embodiment, the television or display device provides the video preview by streaming video to the remote control for display within theEPG 220. Due to the size of the video displayed on the remote, only a low-resolution video stream is required for display on the remote 200. - The information for the
EPG 220 is received by the remote control over the WiFi orradio frequency interface 170. In one embodiment, the television or display that is controlled by the remote 200 also transmits data to the remote 200. This data may be raw EPG data, where programming within thememory 160 of the remote 200 instructs theprocessor 120 how to construct theEPG interface 220 based upon this raw data. Theprocessor 120 would allow the user to interact with the EPG interface, such as by pressing the up or downchannel selectors 224, the change time-frame selectors 226, or by selecting a channel/time coordinate on the EPG grid. Such interaction would cause theprocessor 120 to alter the display based on the raw data received from the television. In fact, theremote control 200 may receive more information from the television than is displayed at one time, allowing the remote control to update the EPG grid without requiring any additional data from the television. In this embodiment, the remote is intelligent and is considered a “fat” or “thick” client of the television. - Alternatively, the television could produce the
EPG interface 220 for the remote 200. In effect, the remote would receive information sufficient to create thedisplay 220, and would forward inputs received on thetouchscreen 210 back to the television for processing. A time change input onselector 226, for instance, would be submitted to the television, which would update the EPG grid and return the updated grid display to the remote 200 for display. In this embodiment, the remote 210 has sufficient intelligence to display the EPG interface and transmit inputs, but most of the intelligence for the EPG display is provided by the television. In effect, the remote 200 is a thin client of the television. - Whether the remote is a thick or thin client, user interaction with the remote is the same. Live video signals can be transmitted from the television to the remote for display on remote, thereby allowing a user to review programming currently showing on other channels without affecting the primary display of the television. This is all accomplished on a remote 200 with an up-facing and active touchscreen whose down-facing buttons or other user inputs are inactive.
- In addition to interacting directly with a television as a thick or thin client, the remote 200 is also able to directly access content and material on the Internet through its
WiFi connection 170.FIG. 6 shows thetouchscreen 210 on remote 200 displaying a “live trivia”contest 230. Thismaterial 230 is designed to relate to the material currently being watched on the television. Based on interaction between the television and the remote 200, the remote has knowledge of the channel and programming currently being viewed. The remote 200 has web access, and therefore is able to download and present interactive content relating to that programming. Alternatively, the television could use its knowledge of the currently displayed programming to feedappropriate content 230 to the remote. - In either case, the remote 200 displays the program currently being viewed, the current channel and time, and then presents
relevant content 230. Interaction with the content can pass through the television as described above in connection withEPG 220. Alternatively, the remote can access therelated content 230 directly through the Internet without any interaction with the television. Therelevant content 230 can allow the user to access other related content as well. For instance,button 232 on thetouchscreen 210 allows the user to access social media websites related to the content, such as a Facebook page or a social media page designed and controlled by the television content provider. Similarly, when the television content is a sporting event,button 234 allows a user to download and view current statistics for the event being viewed. The stats feature could allow the user to view scores and statistics relating to other sporting, or could even access a fantasy web site where a user could track the progress of their fantasy team on their remote 200 without altering the display of the television. In fact, it would even be possible to implement a full web browser and web search (such as through a Google search button 236) on the remote 200. - The
method 300 for operating a remote control is shown in the flow chart shown inFIG. 7 . Themethod 300 starts by waiting for input from one of the remote's input mechanisms atstep 310. Atstep 320, the remote reads its orientation sensor to determine the current orientation of the remote, which is then used bystep 330 to determine whether the input mechanism receiving the input is currently active. In most embodiments, input mechanisms located on a downward-directed face of the remote are inactive, while input mechanisms located on an upward-directed face are active. While this is expected to be the normal configuration, there is no reason that the remote could not be configured to allow some downward facing input mechanisms to remain active, or to deactivate some inputs that are upward facing. - If
step 330 determines that the detected input was from an inactive input, the remote ignores the input and the method returns to step 310 to await the next input. Ifstep 330 determines that the input was active, themethod 300 next determines whether this is an inadvertent repeated input, such as an input caused by a remote being stuck between cushions on a couch. In thismethod 300, this is determined by examining whether the input is repetitive of an earlier input. To determine this, the remote might store one or more earlier inputs in itsmemory 160. If the input is the same as a previous or recent input, or if two or more inputs are alternating, this would be detected by theprocessor 120. Ifstep 340 determines that the input is repetitive,step 350 determines whether the remote's orientation sensor detects any movement. Movement in the remote might indicate that a user is holding the remote and pressing one of the input buttons. Consequently, themethod 300 may elect to allow all repeating inputs whenever the orientation sensor detects movement in the remote. Thisstep 350 could be ignored in some embodiments in order to ensure that the remote handles all inadvertent, repeating inputs appropriately. - If the orientation sensor does not detect movement,
step 360 will determine whether the repeating input has been received for longer than a preset time limit. Without this check, the remote might ignore repetitive inputs desired by the user, such as when a user changes channels by holding down one of the channel change buttons continuously. Ifstep 360 decides that the repeating input has continued for longer than some pre-determined time interval (such as fifteen seconds), the remote ignores this input. In the preferred embodiment, the remote actually turns itself off atstep 370, although it would be possible to simply ignore the input and return to waitingstep 310. Ifstep 360 determines that the repeating input has not exceeded the time limit,step 350 determines that the remote is currently in motion, or ifstep 340 determines that the input is not repeating, the input is performed atstep 380. Performance of the input may be accomplished internally (such as by changing the display on the touchscreen 210), or externally (such as transmitting the command to a remote television or display). After the input is performed atstep 380, the method returns to the waitingstep 310. - The many features and advantages of the invention are apparent from the above description. Numerous modifications and variations will readily occur to those skilled in the art. Since such modifications are possible, the invention is not to be limited to the exact construction and operation illustrated and described. Rather, the present invention should be limited only by the following claims.
