Abstract: The invention concerns a portable data input device. The device comprises a holding member designed to be held by or attached to a first hand of a user of the device in order to hold the device onto said first hand. The device comprises a first plurality of input members arranged on the back of the first hand and/or on the sides of the first hand, such that these input members may be easily manipulated by a plurality of fingers of the second hand of the user. The device also comprises a second plurality of input members arranged on the palm-side of the first hand, such that these input members may be easily manipulated by a plurality of fingers of the first hand. With the help of the input members of the device, essentially all the basic symbols of a standard computer keyboard can be generated. The invention also concerns the use of such a device.

Abstract: The invention concerns a portable unit comprising a hand attachment device, suited to be easily attachable to and removable from a first hand of a person using the device, and at least a first input member arranged on said device for inputting signals to a peripheral unit. The attachment device comprises a U-shaped portion, which thus has first and second at least relatively straight parts and a bent part connecting said first and second parts. The attachment device is designed to be attachable to said first hand such that the first part is located essentially on the back of the hand, the second part is located essentially on the front of the hand while the bent part extends from the back of the hand to the front of the hand in the area between the thumb and the index finger of said first hand. The invention also concerns the use of such a unit.

Abstract: The invention concerns a portable device for inputting control signals to a peripheral unit. The device comprises a holding member designed to be attached to a first hand of a user of the device so as to retain the device in a predetermined manner on said first hand. At least a first input member is arranged on said holding member. The first input member is arranged for inputting signals to the peripheral unit in order to perform the same or a similar function as a joystick or as the movement of a standard computer mouse. Said input member is arranged on said holding member such that when the holding member is arranged as intended on said first hand, the first input member is arranged within a predetermined area of said first hand. The invention also concerns the use of such a device.
