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 change of a resource allocation scheme in a multi-pen supporting electronic apparatus can be made in a shorter period of time than in the prior art. A sensor controller 50 assigns communication resources to one or more pens 2, respectively, and detects a position of each of the one or more pens 2 on the basis of a downlink signal DS received from each of the one or more pens 2 using the assigned communication resources. When changing a resource allocation scheme, which indicates a structure of the communication resources or a method of using the communication resources, the sensor controller 50 broadcasts information indicating a new resource allocation scheme to the one or more pens 2.

A writing interaction method, a smart interactive display device and a writing interaction system are provided. The writing interaction method includes: detecting a first touch event of one or more smart pens and acquiring one or more corresponding identifiers of the one or more smart pens (S100); generating handwriting according to the first touch event (S102A), and determining whether the generated handwriting corresponds to multiple smart pens of the smart pens according to the identifiers of the smart pens (S102B); under a condition that the handwriting corresponds to the multiple smart pens, generating multiple non-overlapping writing regions, wherein the multiple writing regions are in one-to-one correspondence with the multiple smart pens, each writing region covers handwriting of a corresponding smart pen, and each writing region only responds to a touch event of the corresponding smart pen for generating handwriting (S104).

An electronic device and method for collaboration among whiteboard user interfaces (Uls) for meetings is provided. The electronic device controls a display device coupled to the electronic device, to display a first whiteboard UI which is electronically linked with one or more second whiteboard Uls of participant devices for a duration of a meeting session. The electronic device receives inputs corresponding to strokes of a digital pen device on a whiteboard UI of the one or more second whiteboard Uls and prepares content based on the inputs and one or more content filters. Thereafter, the electronic device controls the first whiteboard UI to render the prepared content.

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.

Provided is a communication method for communication performed between a pen and a sensor controller that, in operation, transmits uplink signals to the pen in a frame cycle. The communication method includes transmitting, by the sensor controller, a first uplink signal in a first frame, the first uplink signal including an identifier that identifies a type of data to be transmitted to the pen in a second frame following the first frame, and transmitting, by the sensor controller, a second uplink signal in the second frame, the second uplink signal including a value of the data of the type indicated by the identifier.

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. A presentation remote can be used to obtain information about the presentation and provide it to the audience member.

A system includes a screen and a computer that detects an object near the screen and allows interaction between the object and the computer.

An information handling system stylus transmits a wireless signal at a writing tip to enhance touch detection of the writing tip by a touchscreen display and receives wireless signals from the touchscreen display at a receiving antenna. To enhance control of wireless energy distributed at the writing tip, the receiving antenna is selectively coupled to the writing tip, such as by transitioning from a float of the receiving antenna to an interface with the stylus power source at transmit by the writing tip. Charge at the receiving antenna helps to shape the energy distribution from the writing tip, such as to match the energy distribution of other styluses in use at the touchscreen display.

Systems, devices, media, and methods are presented for selectively activating and suspending control of a graphical user interface by two or more electronic devices. A portable eyewear device includes a display projected onto at least one lens assembly and a primary touchpad through which the user may access a graphical user interface (GUI) on the display. A handheld accessory device, such as a ring, includes an auxiliary touchpad that is configured to emulate the primary touchpad. The eyewear processor temporarily suspends inputs from one touchpad when it detects an activation signal from the other touchpad.
