Patent attributes
A device (100) for handheld operation, such as a mobile phone, a mobile terminal, a smartphone, a User Equipment (UE), a tablet, a phablet, a media player, a remote control, or a gaming console, is provided. The device is operative to detect an imminent or prevailing indication of an unstable operation of the device when being held by a hand (110) of a user of the device, and, in response thereto, to increase a grip between an outer surface (101, 103) of the device and one or more fingers (111-114) of the hand. The grip may, e.g., be increased by generating an adhesive force, or by increasing a friction, between the outer surface and the one or more fingers. Thereby, the risk for the user dropping the device is reduced, and a more convenient operation of the device is achieved, in particularly if operated single-handedly.
