Data Input System, Active Stylus and Method of Controlling of Active Stylus

摘要

According to one embodiment, a data input system includes an active stylus and an apparatus. The active stylus switches a mode from a first mode in which the signal is output with a first transmission interval to a second mode in which the signal is output with a second transmission interval longer than the first transmission interval when a pressure in a handwriting input operation is not detected for more than a first period. The apparatus displays an object indicative of a position pointed to by the active stylus based on the signal. The apparatus maintains, when the active stylus is in the second mode, a display state of the object displayed on the basis of the signal output at a first timing until the signal is output at a second timing following the first timing.

1. A data input system comprising an active stylus and an apparatus comprising a sensor to detect a signal of the active stylus,
the active stylus comprising: an output controller configured to output a wireless signal; a pressure sensor configured to detect a pressure in a handwriting input operation; and a controller configured to switch the active stylus from a first mode to a second mode when the pressure is not detected by the pressure sensor for more than a first period, the first mode being a mode in which the output controller outputs the wireless signal with a first transmission interval, the second mode being a mode in which the output controller outputs the wireless signal with a second transmission interval longer than the first transmission interval, the apparatus comprising a display controller configured to display an object indicative of a position pointed to by the active stylus which is not in contact with an operation surface based on the wireless signal output from the active stylus, the display controller being configured to maintain, when the active stylus is in the second mode, a display state of the object displayed on the operation surface based on the wireless signal output at a first timing until the wireless signal is output at a second timing following the first timing.
