An electronic pen is realized which includes a side switch that has a simple configuration and enables instruction inputs of a plurality of states to be performed easily and properly. The electronic pen has a side switch unit provided at a side surface of a pen body to be gripped by a user. The side switch unit includes a sensor unit in which capacitive sensors and pressure sensing sensors are provided as two kinds of touch sensors of different detection systems such that sensor regions (detection regions) are superimposed on each other. Thus, at least a case of performing an operation in such a manner as to act on one touch sensor and a case of performing an operation in such a manner as to act on both touch sensors simultaneously can be indicated through the side switch unit.

A handwriting data generation apparatus includes a memory containing processor-executable instructions and a processor coupled to the memory. The processor is configured to perform, when loaded with the processor-executable instructions, associating tactile feedback with at least part of stroke data generated according to handwriting input, and generating digital ink including haptics data indicating the stroke data and the tactile feedback.

Handwritten data generation apparatus, handwritten data reproduction apparatus, and digital ink data structure

An information sharing system includes a plurality of terminal devices and an information sharing device communicable with the terminal devices. Each of the terminal devices includes a display unit which displays content in a display region, and a processor which performs display control over the display unit. The information sharing device includes a classification processing unit which classifies a plurality of users of the terminal devices into groups in reference to a result of evaluation of pieces of stroke data each indicating the content handwritten by a user of a corresponding one of the terminal devices. The information sharing device includes a display instruction section which instructs each of terminal devices corresponding to two or more constituent members belonging to one of the groups classified by the classification processing unit, among the terminal devices, to display a status information column indicating states of the two or more constituent members.

Information sharing system, method, and program

Provided is a pen data storage apparatus that stores pen data including at least coordinate data regarding a position instructed and input by an electronic pen, in units of the pen data, in which each piece of the stored pen data includes function identification information that identifies a processing function for the pen data.

A position detection device includes a position detection sensor including a position detection region corresponding to an instruction input surface for receiving an instruction input by an indicator, a position detection circuit which, in operation, detects at least a position of an instruction in the position detection region of the position detection sensor based on an interaction of the position detection sensor and the indicator, and a plurality of motion sensors. The position detection sensor includes a flexibly displaceable part that is deformable together with the instruction input surface according to an operation of a user, and the flexibly displaceable part is disposed between two of the motion sensors.

Position detection device

An image processing device includes a processor; and a memory coupled to the processor, the memory storing a program that, when executed by the processor, causes the image processing device to: obtain first coordinate data indicating a coordinate position indicated by a position indicator from a sensor that detects the coordinate position; obtain first image data to which predetermined additional information is added; and associate the first image data with position data indicating a position on a display screen of a display device, the position corresponding to the first coordinate data.
