Abstract

An information processing system includes: a sensor unit that performs detection of contact of a pen-shaped input device with an operation target surface and presence of the pen-shaped input device within a detection limit distance on the operation target surface; a sound output unit that outputs a sound corresponding to input sound data; and a sound output control unit that inputs silent sound data to the sound output unit in response to the sensor unit detecting a first state in which the pen-shaped input device is detected within the detection limit distance, and inputs audible sound data to the sound output unit in response to the sensor unit detecting that, after the first state, a second state in which the pen-shaped input device is in contact with the operation target surface has been reached.

Claims (12)

1 . An information processing system comprising:

a sensor unit that performs detection of contact of a pen-shaped input device with an operation target surface and presence of the pen-shaped input device within a detection limit distance on the operation target surface;

a sound output unit that outputs a sound corresponding to input sound data and that includes:

a sleep state that requires a warm-up period before outputting the sound; and

an operating state that does not require a warm-up period before outputting the sound; and

a sound output control unit that

inputs silent sound data to the sound output unit in response to the sensor unit detecting a first state in which the pen-shaped input device is detected within the detection limit distance, wherein the silent sound data causes the sound output unit to start the warm-up period before the pen-shaped input device is in contact with the operation target surface, and

inputs audible sound data to the sound output unit in response to the sensor unit detecting that, after the first state, a second state in which the pen-shaped input device is in contact with the operation target surface has been reached.

2 . The information processing system according to claim 1 , wherein

the sound output control unit stops inputting the sound data to the sound output unit in response to the sensor unit detecting a transition from the second state to a third state in which the pen-shaped input device is separated from the operation target surface.

3 . The information processing system according to claim 2 , wherein

the sound output control unit stops inputting the sound data to the sound output unit in response to the third state having continued for a predetermined period of time from a time of the transition from the second state to the third state.
