  • Patent number: 10599312
    Abstract: Apparatus and method are provided that are capable of controlling a display in response to reliable detection of a sliding movement operation of a pointer (e.g., a user's finger) that passes through an end of a display region. The apparatus and method utilize a position detection sensor, which is superposed on the display and configured to detect the pointer's position discretely and successively at a predetermined time interval. Based on a first position detected by the position detection sensor and a second position detected, at the predetermined time interval since the detection of the first position, by the position detection sensor, which together indicate a moving operation of the pointer, it is determined whether the moving operation of the pointer has crossed an end of the display region. If it is so determined, a passed end position of the display region is calculated based on the first and second positions.
