摘要:
A remote control apparatus for communicating with a target device includes: a sensing portion for sensing points of user contact with the apparatus, user gestures, and an acceleration value of the apparatus; a transmitting device for sending signals representative of user commands to the target device; a controller; and a memory including instructions for configuring the controller to perform a self-orientation process based upon at least one of the acceleration value and the points of user contact to determine a forward direction of a plane of operation for defining the user gestures. An axis of the determined plane of operation substantially intersects the apparatus at any angle.

A method and system for differentiating between intended user input and inadvertent or incidental contact with a touchpad is herein disclosed. When a user engages the touchpad, sensors on the touchpad are activated and generate touch sensor signals. Based on the pattern of engaged sensors, a hand pattern can be determined. From the hand pattern, a hand model may be retrieved. The hand model may indicate passive zones and active zones. Contact in the active zones may be considered intentional, while contact in the passive zones may be considered unintended or incidental. Moreover, a global shift may be calculated, and input from the active zones may be compensated for the global shift. The input from the active zones can then be used to control a graphical user interface.

A noise robustness method operates jointly in a signal domain and a model domain. For example, energy is added in the signal domain for frequency bands where an actual noise level of an incoming signal is lower than a noise level used to train models, thus obtaining a compensated signal. Also, energy is added in the model domain for frequency bands where noise level of the incoming signal or the compensated signal is higher than the noise level used to train the models. Moreover, energy is never removed, thereby avoiding problems of higher sensitivity of energy removal to estimation errors.

Sensors around the periphery of the remote control unit detect contact with the user's hand. A trained model-based pattern classification system analyzes the periphery sensor data and makes a probabilistic prediction of the user's hand size. The hand size is then used to control a mapping system that defines how gestures by the user's thumb upon a touchpad of the remote control unit are mapped to the control region upon a separate display screen.

The handheld case of the remote control unit includes at least one touchpad, and other sensors, such as acceleration sensors, case perimeter sensors, pressure sensors, RF signal sensors. These sensors provide a rich array of sensory inputs that are classified by a pattern recognizer to generate control commands for both the consumer electronic equipment and the remote control unit itself. A power management system to conserve unit battery power is also responsive to the pattern recognizer to allow intelligent power management control. The control system uses the display of the consumer electronic equipment to provide instructions to the user, and the behavior of the remote control system uses what is displayed on the display as context information for pattern recognition.
摘要:
A remote control unit selectively transmits a control signal for remotely controlling an electronic device. The unit defines an imaginary cut plane that substantially bisects the unit. The unit includes a plurality of input features collectively disposed symmetrically with respect to the imaginary cut plane. The input features include a first and second input feature. The first and second input features are disposed on opposite sides of the cut plane. Furthermore, the unit includes a sensor that detects a first and second holding position of the unit. The first holding position and the second holding position are substantially opposite to each other. Moreover, the unit includes a controller that associates the control signal with the first input feature when the sensor detects the first holding position, and the controller associates the control signal with the second input feature when the sensor detects the second holding position.

A language model back-off system can be used with a user interface employing one or more language models to constrain navigation of selectable user interface input components. A user input interpretation module receives user input and interprets the user input to determine if a selection is made of one or more user interface input components. If a selection is not made, the user input interpretation module determines whether conditions are met for backing off one or more language models employed to constrain navigation of the user interface input components. If the conditions are met, a language model back-off module backs off the one or more language models.

摘要:
A system and method for identifying a user of a handheld device is herein disclosed. The device implementing the method and system may attempt to identify a user based on signals that are incidental to a user's handling of the device. The signals are generated by a variety of sensors dispersed along the periphery or within the housing. The sensors range may include touch sensors, inertial sensors, acoustic sensors, pulse oximiters, and a touchpad. Based on the sensors and corresponding signals, identification information is generated. The identification information is used to identify the user of the handheld device. The handheld device may implement various statistical learning and data mining techniques to increase the robustness of the system. The device may also authenticate the user based on the user drawing a circle, or other shape.
