Abstract

A touch processing method and a mobile terminal are described. The mobile terminal includes a touch sensing device that has a first area and a second area. A touching point in the first area has a first response level and a touching point in the second area has a second response level, with the first response level being higher than the second response level. The method includes acquiring a first touching point and a second touching point; and responding to the first touching point when the first touching point is in the first area while the second touching point is in the second area. When a user holds the mobile terminal to operate, the mobile terminal may respond to useful touch commands automatically and shield touch commands generated by the misoperation in the second area.
