Abstract: The invention relates to a flexible fitting solution for a portable device for inputting control signals to a peripheral unit, which includes a holding member designed to be attached to a hand of a user of the device so as to retain the device in a predetermined manner on the hand. The holding member comprises at least one elongated portion and at least one curved portion connected thereto. A side of the holding member that faces the user's hand when the device is attached to the hand includes a padding module. The padding module, in turn, includes at least one pad cushion adapted to fit the device to the user's hand. The padding module is removably fastened to the holding member by means of a set of fastening members, which secure the padding module in a fastened position. By selecting an appropriate padding module, each user of the device may obtain a good fit of the device onto his/her hand.
