A “Constrained Predictive Interface” uses predictive constraints to improve accuracy in user interfaces such as soft keyboards, pen interfaces, multi-touch interfaces, 3D gesture interfaces, EMG based interfaces, etc. In various embodiments, the Constrained Predictive Interface allows users to take any desired action at any time by taking into account a likelihood of possible user actions in different contexts to determine intended user actions. For example, to enable a virtual keyboard interface, various embodiments of the Constrained Predictive Interface provide key “sweet spots” as predictive constraints that allow the user to select particular keys regardless of any probability associated with the selected or neighboring keys. In further embodiments, the Constrained Predictive Interface provides hit target resizing via various piecewise constant touch models in combination with various predictive constraints. In general, hit target resizing provides dynamic real-time virtual resizing of one or more particular keys based on various probabilistic criteria.

An apparatus and method for providing multi-touch human to computing device interface capability on devices having single-touch interface devices. The apparatus and method use heuristics based analysis of successive touch point X,Y coordinate pairs provided by the single-touch interface device to identify a multi-touch occurrence. A further heuristics based function is employed to derive X,Y coordinates for a second touch point from two successive pairs of X,Y coordinates provided by single-touch interface device.

This is directed to controlling media playback based on particular touch gestures detected by a touch-sensing interface. The electronic device can identify particular touch inputs, such as combinations of tapping and holding a touch sensitive surface, or circular motions. In response to detecting a particular touch gesture, the electronic device can perform a playback operation specifically associated with the detected touch gesture. To provide a consistent user interface with the device, some of the particular touch gestures can match other inputs provided using a button, for example a button integrated on a wired headset. In such an embodiment, the same combination of tapping and holding a touch input and pressing and holding a button can control the same electronic device operations.

A system and a method are disclosed for providing a touch interface for electronic devices. The touch interface can be any surface. As one example, a table top can be used as a touch sensitive interface. In one embodiment, the system determines a touch region of the surface, and correlates that touch region to a display of an electronic device for which input is provided. The system may have a 3D camera that identifies the relative position of a user's hands to the touch region to allow for user input. Note that the user's hands do not occlude the display. The system may render a representation of the user's hand on the display in order for the user to interact with elements on the display screen.

The present invention relates to a method for representing musical scales by means of tiles, including pentatonic scales (arbitrary scales with five notes per octave), heptatonic scales (arbitrary scales with seven notes per octave). Major blues and Minor blues scales (specific scales with six notes per octave), and to an electronic musical device with an interface that uses this representation. More specifically, the device uses a multi-touch interface with or without strings which allows the musician to concentrate on the melodic line only, making it easier to improvise and perform music composed in one of said scales. The representation differs from the traditional interfaces on string instruments (such as a guitar) in that only the notes of a given scale (with five, six or seven notes per octave) can be played.

Apparatus and methods are disclosed for controlling multiple parameters on a multi-touch surface. Design of the apparatus and the multi-touch gestures enable unprecedented control of parameters by allowing the user to alter multiple parameters blindly in real-time with varying sensitivity.

An apparatus and method including a multi-touch interface for card gaming includes providing a multi-touch interface for displaying a card having a hidden value. The method includes detecting a touch on the interface. The touch has a curved pattern with multiple points of contact with the interface. The curved pattern is indicative of the lateral edge of a human hand in contact with the interface, oriented to hide the card from others. The method then detects movement of the multiple points of contact sweeping over a portion of the interface to reveal the value of the card to the user.

Described herein are systems and methods that employ a widgetless and buttonless multi-touch interface for constrained manipulations of 3D objects. The widget-less multi-touch user interface can map different multi-touch gestures to different 3D object manipulation tasks, allowing a user to manipulate 3D objects without operating widgets or performing mode switchings or tool selections. User interaction is greatly simplified by using single touch actions that simultaneously specify the transformation constraint, the transformation type, and the magnitude of transformation and apply the transformation to the focus object. Additionally, the axis-based constrained manipulations support active snapping and axis transfer. Active snapping allows the user to draw a free touch path connecting two 3D objects to be snapped together, avoiding tedious operations required with standard transformation manipulations. Axis transfer provides a simple solution to achieve relative transformations between objects, allowing an object to be transformed along a specific predefined axis of another object.

A method for navigating within a search result obtained with a search engine installed on an electronic device, wherein a list of results is obtained from a data server, the navigation method including: identifying, in each result in the list of results, first components of the result considered, and second components of the result considered; organizing the first components into a first sub-list of results and the second components into a second sub-list of results; restoring the first sub-list of results into a first display area of the screen, and the second sub-list of results into a second display area of the screen; synchronizing the selection of a result in the first sub-list of results with the selection of a corresponding result in the second sub-list of results; and using a multi-touch interface in order to select a search result spread over a plurality of lists showing a different view of the same information.

A capacitive touch key is a common user interface device. A sensor judges whether a finger touch action exists or not by detecting the capacitance of a human body. Compared with a mechanical key, thecapacitive sensor is attractive in appearance, easy to use and long in service life. However, if a water film or water drops exist on the touch interface, the capacitance of the sensor is changed, andmistaken touch induction may occur. The invention provides a hardware waterproof capacitive touch key BUF circuit. The BUF circuit has the advantages of being simple in structure, low in power consumption and high in speed.

A process to experience a two touch interface with single touch functionality is disclosed. Use of two fingers simultaneously presents a degree of freedom constraint on the hand. In an embodiment of the present invention, the simultaneous two touch interface is simulated using a single touch process. In a special input mode, a mechanism is used to first fix a point of reference. A second and subsequent single touch with respect to the fixed point of reference is then made. The time skewed touches enable free use of the index finger for both touches. Closed figures are easily drawn and zoom in and zoom out functions are similarly implemented by a point of reference and a line traced away from or to the object. Limitations of the dual touch are overcome, while maintaining full interface capability of the dual touch.
