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

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.
