Abstract: An information processing device includes: an operation receiver capable of receiving a plurality of gesture operations; and a controller including a microprocessor and configured to perform a control for reflecting a gesture operation on a screen on a basis of an output from the operation receiver. The controller sets a threshold value of a determination index for determining whether the gesture operation is valid for each of the gesture operations, provides a measured value of the determination index of a gesture operation received by the operation receiver and compares the measured value with the threshold value to determine whether the gesture operation is valid, reflects the valid gesture operation on the screen, and variably sets a threshold value corresponding to a gesture operation other than the valid gesture operation in accordance with an execution state of the gesture operation received by the operation receiver.

Abstract: A conference support apparatus includes a controller connected communicably to a display and an operation acceptor, wherein the controller manages an individual work region applicable to a display region of each of terminal apparatuses; analyzes an operation performed by user via the operation acceptor; causes each display to display a screen in which an object operation in each of the individual work regions of the terminal apparatuses is reflected; predicts a target object for operation based on the result of analysis; and suppresses an operation of the predicted target object in a specific terminal apparatus including the predicted target object in the individual work region, the specific terminal apparatus being a terminal apparatus other than a terminal apparatus whose object has been predicted as the target object according to the operation therein, among the terminal apparatuses.

Abstract: A handwriting input device includes: a first detection unit that has an input surface to which inputting of information is allowed by direct contact of a contact body or contact of the contact body via a sheet and detects as contact information at least one of contact pressure and contact area of the contact body on the input surface; a second detection unit that detects vibrations generated by the contact as vibration information; and a contact body determination unit that determines the kind of the contact body based on the contact information and the vibration information.
