  • Patent number: 11301127
    Abstract: Methods and apparatus are provided for correcting an input error in an input apparatus capable of touch inputs of a first touch input scheme and a second touch input scheme. Upon detecting a touch input of the first touch input scheme, an activity corresponding to the detected touch input is executed and activity execution information corresponding to the activity is stored. The activity executed in accordance with the touch input of the first touch input scheme is cancelled, when a touch input of the second touch input scheme occurs before the touch input of the first touch input scheme is released or before a preset timer expires. The first touch input scheme and the second touch input scheme are different schemes.
