A redundant tracking system comprising multiple redundant tracking sub-systems, enabling seamless transitions between such tracking sub-systems, provides a solution to this problem by merging multiple tracking approaches into a single tracking system. This system is able to combine tracking objects with six degrees of freedom (6DoF) and 3DoF through combining and transitioning between multiple tracking systems based on the availability of tracking indicia tracked by the tracking systems. Thus, as the indicia tracked by any one tracking system becomes unavailable, the redundant tracking system seamlessly switches between tracking in 6DoF and 3DoF thereby providing the user with an uninterrupted experience.

A position detection apparatus includes a sensor, and a controller that detects a position of a first position indicator and a position of a second position indicator through the sensor. The controller continues detecting the position of the first position indicator and halts detecting the position of the second position indicator after a state in which the positions of the first position indicator and the second position indicator are not detected changes to a state in which the position of the first position indicator is detected, and continues both detecting the position of the second position indicator and detecting the position of the first position indicator after the state in which the positions of the first position indicator and the second position indicator are not detected changes to a state in which the position of the second position indicator is detected.

An apparatus for manipulating an object includes first and second gesture controllers, each operatively connected to the object and structured and programmed such that, in a first-action active state, each can causes a first action to be carried out on the object by an appropriate first-action gesture made in the gesture controller. Only one of the first and second gesture controllers at any given time is capable of being in the first-action active state, and the first-action active state is transferable between the first and second gesture controllers upon the detecting of a first-action transfer gesture by one of said first gesture controller and said second gesture controller. Specific gesture control apparatus and methods for manipulating an object are also disclosed.

The present application provides a synchronization method and a synchronization device, which may effectively realize synchronization between a touch screen and the active pen. The synchronization method is configured for time synchronization between a first detection chip of a first device and a second detection chip of a second device, and the method includes: a first wireless communication chip connected to the first detection chip, receiving the first synchronization signal sent by the first detection chip at a first moment; the first wireless communication chip sending time information associated with the first moment to a second wireless communication chip connected to the second detection chip; and the time information being configured to determine a second moment for the first detection chip to send the synchronization signal next time, so that the second detection chip is synchronized with the first detection chip at the second moment.

In accordance with some embodiments, systems, apparatus, interfaces, methods, and articles of manufacture are provided for ascertaining aspects of a presentation and/or of an audience member.

An object of the present invention is to provide a technique for providing a detection function of detecting that an external approaching object approaches a sensor region of a touch sensor, without increasing an area of the touch sensor and making a circuit complex. According to an aspect, a display device includes a first detection electrode that detects a position of an external approaching object within a detection surface, and plural second detection electrodes that detect that the external approaching object approaches the detection surface. The second detection electrodes extend in a second direction and are arranged in a first direction intersecting the second direction. The second detection electrodes overlap the first detection electrode in a plan view.

A position detection apparatus includes a sensor, and a controller that detects a position of a first position indicator and a position of a second position indicator through the sensor. The controller continues detecting the position of the first position indicator and halts detecting the position of the second position indicator after a state in which the positions of the first position indicator and the second position indicator are not detected changes to a state in which the position of the first position indicator is detected, and continues both detecting the position of the second position indicator and detecting the position of the first position indicator after the state in which the positions of the first position indicator and the second position indicator are not detected changes to a state in which the position of the second position indicator is detected.

A method includes presenting a representation of a multi-panel display of an operator console on a touchscreen separate from the multi-panel display. The representation includes multiple placeholders associated with multiple panels of the multi-panel display. The method also includes receiving user input via the touchscreen, where the user input identifies at least one of the placeholders associated with at least one of the panels and a desired function. The method further includes performing the desired function to one of change first content presented in the at least one panel or change second content presented on the touchscreen based on the first content presented in the at least one panel. The desired function could include pushing the first content to the at least one panel or pulling the second content from the at least one panel.

An ink file output method is provided, which includes: generating M (M is an integer of 1 or more) pieces of stroke data SD on the basis of event data generated as M input devices move, respectively; generating N (N is an integer of 1 or more and M or less) kinds of logical names LN (metadata) identifying the M number of input devices; generating a metadata block associating the M pieces of stroke data SD with the N kinds of logical names LN; and writing the M pieces of stroke data SD and the metadata block to an ink file.

A method, device and system for collecting writing pattern using Body Area Network, BAN, wherein the BAN comprises at least one BAN enabled writing device, e.g. a pen and at least one wearable BAN enabled communication device, e.g. a wristlet, worn by a user, wherein a BAN link is established through the body of the user between the writing device and the communication device, when the user touches the writing device, the writing pattern is created and collected by using the writing device and streamed from the writing device to the wearable device by using the established BAN link.
