In one aspect, the electronic device includes a housing, a touch screen with edges, and one or more processors. First and second touch recognition regions are defined adjacent to one of the touch screen edges. The one or more processors determine whether to ignore a touch input based at least on whether the touch input is in one of the first and second touch recognition region and at least one of the type and the duration of the touch input. ## Claims ### Claim 1 An electronic device, comprising: a housing;
