摘要:
A “Contact Discriminator” provides various techniques for differentiating between valid and invalid contacts received from any input methodology by one or more touch-sensitive surfaces of a touch-sensitive computing device. Examples of contacts include single, sequential, concurrent, or simultaneous user finger touches (including gesture type touches), pen or stylus touches or inputs, hover-type inputs, or any combination thereof. The Contact Discriminator then acts on valid contacts (i.e., contacts intended as inputs) while rejecting or ignoring invalid contacts or inputs. Advantageously, the Contact Discriminator is further capable of disabling or ignoring regions of input surfaces, such tablet touch screens, that are expected to receive unintentional contacts, or intentional contacts not intended as inputs, for device or application control purposes. Examples of contacts not intended as inputs include, but are not limited to, a user's palm resting on a touch screen while the user writes on that screen with a stylus or pen.

摘要:
A physically-modulated friction stylus system and method for physically modulating friction between a styli tip and a surface of a computing device to emulate the “feel” of different types of writing instruments writing on different types of surfaces (such as pen on paper or a paintbrush on canvas). The actual friction between the stylus and the surface is modulated to produce the “feel.” The friction is physically modulated “on the fly” meaning that friction can be modulated while the stylus tip is in contact with the surface and while the stylus is moving. The friction is modulated dependent on a location of the stylus on the surface and the posture and orientation of the stylus. In addition, the friction can be modulated based on a direction and a velocity that the stylus tip is moving across the surface. Audio may also be used to improve the emulation experience.

A local user of a local mobile device is allowed to participate in a video conference session with a remote user of a remote mobile device. Live video can be shared between and collaboratively digitally annotated by the local and remote users. An application can also be shared between and collaboratively digitally annotated by the local and remote users. A digital object can also be shared between and collaboratively digitally annotated by the local and remote users.

摘要:
A “Concurrent Projector-Camera” uses an image projection device in combination with one or more cameras to enable various techniques that provide visually flicker-free projection of images or video, while real-time image or video capture is occurring in that same space. The Concurrent Projector-Camera provides this projection in a manner that eliminates video feedback into the real-time image or video capture. More specifically, the Concurrent Projector-Camera dynamically synchronizes a combination of projector lighting (or light-control points) on-state temporal compression in combination with on-state temporal shifting during each image frame projection to open a “capture time slot” for image capture during which no image is being projected. This capture time slot represents a tradeoff between image capture time and decreased brightness of the projected image. Examples of image projection devices include LED-LCD based projection devices, DLP-based projection devices using LED or laser illumination in combination with micromirror arrays, etc.

The recognition of user input to a computing device is enhanced. The user input is either speech, or handwriting data input by the user making screen-contacting gestures, or a combination of one or more prescribed words that are spoken by the user and one or more prescribed screen-contacting gestures that are made by the user, or a combination of one or more prescribed words that are spoken by the user and one or more prescribed non-screen-contacting gestures that are made by the user.
