Information processing apparatus and operation method thereof for determining a flick operation of a pointer

摘要

There is provided an information processing apparatus with an interface with high convenience for a user. A reference speed is set according to an amount of movement or a movement time period of a pointer of a stylus or a finger. It is determined based on a movement speed of the pointer and the reference speed that a flick operation with the pointer has occurred.

主权项

1. An information processing apparatus configured to determine a flick operation of a pointer, the information processing apparatus comprising a processor coupled to a memory, the processor being programmed to:
display an image on a predetermined screen; acquire position information of each of one or more touched positions periodically detected on a touch panel; acquire an amount of movement of the pointer during input of one stroke, based on the position information of a plurality of touched positions periodically detected from when the pointer touched the touch panel to before the pointer is released from the touch panel; acquire a movement speed as a speed of the pointer when the pointer is released from the touch panel, based on the position information of a plurality of touched positions periodically detected before the pointer is released from the touch panel; select a speed threshold from a plurality of speed thresholds based on the amount of movement of the pointer during the input of one stroke; determine that the flick operation of the pointer has occurred at the end of the movement in a case where the movement speed exceeds the speed threshold selected by the processor; and move the image displayed on the predetermined screen, in a case where it is determined that the flick operation has occurred based on the movement speed and the speed threshold selected by the processor, in a direction of the flick operation after the pointer is released from the touch panel.
