    Abstract: Provided is an electronic device including an input means using a touch panel with which incorrect operations is reduced. When people whose arms, hands, or fingers involuntarily shake because of cerebral palsy or the like use an input system including a touch panel, incorrect touch might occur in input operation. To prevent this, a touch input system in which a cover for preventing incorrect touch is provided over a touch panel to reduce incorrect operations is provided. However, since there is a region that is hard to touch using the cover, electronic devices including such touch panels are not sufficiently widely used. Thus, novel touch panels are provided outside a display region where the cover is provided. The touch panels have a function of selecting first and second regions. The first and second regions intersect with each other to provide a third region. A display object displayed in a region overlapping with the third region is configured to be extracted and executed.
