Further, the present invention encompasses present and future known equivalents to the known components referred to herein by way of illustration.
FIG. 1 is a block diagram that illustrates general aspects of embodiments of the invention. As shown, a remote control device 100 communicates with a receiver 102. The receiver 102 is coupled to a graphical user interface 104 that controls a display 106. Device 100 includes conventional remote controls such as a numeric keypad 110, media playback controls 112, and menu controls 114, as well as a transmitter (not shown) to communicate control selections to receiver 102. According to aspects of the invention, however, device 100 further incorporates 3-axis motion sensors (gyro) such that displacement, velocity and acceleration as well as roll, pitch and yaw information is captured and sent to receiver 102. In addition to using the three axis movement communicated by device 100 for cursor location, GUI 104 can use the motion sensor information in many new and useful ways. As one example, information about movement along the ±Z axis can be used to activate a “zoom in” function when remote pointed toward the screen and “zoom out” when it is pulled back. As another example, and although not shown in detail in FIG. 1, the device 100 can include controls on an opposite side from controls 110, 112 and 114, and the motion sensors can be used to activate controls on one side of device 100 and deactivate controls on the other side based on its orientation.
Although shown separately in FIG. 1, receiver 102, GUI 104 and display 106 can be included in a single device such as a television. Alternatively, receiver 102 and GUI 104 can be included in a device such as a set top box, and display 106 can be a conventional television. Many other variations are possible. For example, receiver 102 and GUI 104 can be included in a personal computer running a conventional operating system such as Windows or Mac OS, either internally or externally (e.g. via a USB dongle or the like), or combinations of both. Still further, certain or all of the functionalities and/or components of device 100, GUI 104 and 106 can be incorporated into a single device such as a smart phone (e.g. iPhone, Android, etc.), a PDA, a tablet computer (e.g. iPad), a personal media player, etc. In such embodiments, receiver 102 may be unnecessary. Those skilled in the art will recognize how to adapt the invention for use in such various environments after being taught by the examples described herein.
As such, GUI 104 can be implemented depending on the particular environment. In one example where receiver 102 and GUI 104 are provided together in a set top box, GUI 104 can be software that receives information from receiver 102 and works with an embedded operating system and/or application software to control menu selections, media playback, zooming and panning, etc. In embodiments where receiver 102 and 104 are implemented in a personal computer, some or all of GUI 104 can be part of a device driver operating under an operating system such as Windows or Mac OS. Those skilled in the art will understand how to adapt GUI 104 for use with such various implementations after being taught by these examples. In particular, those skilled in the art will understand how to implement standard GUI functionalities such as cursor pointing, as well as screen zooming functionalities, using the motion sensor inputs of the invention after being taught by the present disclosure.
Communications between device 100 and receiver 102 can use any wireless or wired technology, such as IrDA, Bluetooth, WiFi, USB, etc. Moreover, well known protocols such as RF4CE, 802.15.4 can be used.
A block diagram illustrating an example embodiment of device 100 is provided in FIG. 2. As shown in this example, device 100 includes motion sensors 202, controller 204, transmitter 206, keypad controller 208, USB interface 210 and NFC 212.
In embodiments, motion sensors 202 can include any commercially available MEMS-type accelerometers and/or gyroscopes, such as a STMicroelectronics L3G3250A. Although full 3-axis motion (X, Y, Z) and orientation (roll, pitch, yaw) are preferred, detecting all axes of motion and orientation are not necessary.
In embodiments, controller 204 is a programmable processor such as a STMicroelectronics ST72F651AR6T1E that includes associated program and data memory (not shown) that implements the functionalities of the present invention. Those skilled in the art will understand how to implement this functionality in a processor after being taught by the present disclosure.
In embodiments, transmitter 206 is a wireless transmitter such as an infrared optical transmitter that is typically used in conventional remote control devices. In one example, transmitter 206 is a Sanyo LC7464M. In other embodiments, transmitter 206 is a radio transmitter such as Bluetooth or WiFi, or a wired interface such as USB (in which case interface 210 may be unnecessary).
In embodiments, keypad controller 208 is any conventional keypad controller that detects keypad presses and sends corresponding information to controller 204. In one example, keypad controller 208 is a Sanyo LC7464M. Those skilled in the art will appreciate that many alternative types of controllers can be used depending on the type and number of keypad inputs, such as touch pads, scroll wheels, etc.
In embodiments, USB interface 210 is a conventional USB interface that can be used to recharge a battery in device 100 (not shown) and/or to receive software updates for controller 204.
In embodiments, NFC 212 is a near-field communication (NFC) device, such as a Melexis MLX90131, using a communication protocol such as that defined by the NFC Forum. In example embodiments, this can be used to share profile information or credentials with a paired device. Additionally or alternatively, NFC can be used to pass secure information regarding payment, such as a token, pin or other form of identification to authorize to a bank account. For example, NFC 212 can be used in a security scheme to activate functionality with a paired device such as a computer or set top box and/or to activate functionalities and capabilities according to user profile, etc. It is possible that other security mechanisms can be used in addition to, or alternatively to NFC technology, including smart cards, login credentials, biometrics, etc.
In operation, general operation controller 204 receives information regarding movement from motion sensors 202 and information regarding control selections from keypad controller and formats and sends corresponding information via transmitter 206. It should be noted that motion information and keypad information can be used independently or in combination. Moreover, controller 204 can use movement information to activate and deactivate certain of controls from keypad controller 208. For example, depending on orientation as detected by sensors 202, controls on different sides of the device 100 can be activated and deactivated.
It should be apparent that other embodiments of device 100 can have fewer or additional components as illustrated in FIG. 1.
The following is a further detailed description of a device 100 in connection with an example implementation as a full function remote control and keyboard to support ViaCLIX Total Access Centers (“TAC”) from Family Series V50xx and beyond, as well as providing a remote control that will work with television receivers attached to the V50xx Series systems. As such, the TAC incorporates the functionality of receiver 102 and GUI 104 as described above. In addition, this example implementation of device 100 provides full functionality for ViaBrowsers running under Windows 7 on industry standard personal computers. As should be appreciated, the invention is not limited to this example embodiment, but can be extended to use with other systems.
Cursor positioning of the Remote Control is enabled by the use of 3-axis motion sensors (gyro) providing a rapid cursor movement that can be scaled for individual capabilities for television viewing at a ten foot distance. Displacement, velocity and acceleration as well as roll, pitch and yaw may be provided for a wide range of applications running on the TAC. In addition to using the three axis for cursor location, the Remote Control will use movement along the ±Z axis to activate “zoom in” when remote pointed toward the screen and “zoom out” when it is pulled back.
An example embodiment is shown in FIG. 3, which shows top, bottom and side views of device 100. In this example, there are two active sides to the controller: one containing a television/media player Remote Control 302; and the other including a Remote Keyboard 304. When the Remote Control side of the controller is up, as determined by the gyro, the keys on the Remote Keyboard side of the controller are to be disabled, and vice versa. The television/media player control signals are transmitted via infra red signaling and the TAC control and data signals are transmitted via a 2.4 GHz radio frequency (RF4CE based upon 802.15.4) to a receiver 102 installed in the TAC. There is an infra red emitter 306 located in the top end of the Remote Control and a mini-USB (“Type B”) on the bottom end for recharging and loading new software.
The RF4CE receiver 102 is located inside the TAC and can be interfaced to a USB input port on the receiving system. The Remote Control is “paired” with the receiver to minimize interference with other equipment in the home and the receiving system “wake on signal” is assumed.
Except for a broader range of control functions than are usually found on a remote control, the device 100 can perform in much the same way as any typical audio/video remote control. In embodiments, the device communicates with the TAC using a 2.4 GHz code scheme (RF4CE, 802.15.4) with human interface device (HID) codes for each key on control 302 and keyboard 304, as well as for detected motion from the embedded motion sensors. It can also communicate with the television using a “learning” infra red code.
The Remote Keyboard 304 preferably utilizes a Unicode two-byte code set to permit keyboard HID code modifications for international customization. The gyro subsystem generates the necessary control codes to permit at least the following data to be sent to the TAC receiver: ±X; ±Y; ±Z.
As shown in FIG. 3, in this example embodiment, remote control 302 includes the following controls: Zone 1—Audio/Video Controls; Zone 2—Navigation Control; and Zone 3—Special Function and Number Pad. Moreover, this example contains a charging control circuit that is powered from a standard USB “Type B,” 5VDC power adaptor.
Although the present invention has been particularly described with reference to the preferred embodiments thereof, it should be readily apparent to those of ordinary skill in the art that changes and modifications in the form and details may be made without departing from the spirit and scope of the invention. It is intended that the appended claims encompass such changes and modifications.
