A portable electrical control and display device is described, having an indicator panel, a keyboard with at least one key pad, and a single housing designed as a single piece and made of a temperature-resistant material, which seals the control and display device in a water-tight manner. ing the front actuator mounted on the downward side of the projection, whereby the front actuators can be activated by substantially wrapped fore-, middle or ring finger and are protected from unintentional vertical downward and horizontal inward activation. 9. The device of claim 1, wherein the front-side actuators are mounted above the fingers, whereby the user's hand is safely resting on the shell of virtually any shape and activation clicks are performed by unbending or upward moves of fore-, middle, or ring finger. 10. The device of claim 9 further comprising a thumb actuator mounted on the left side, whereby said thumb actuator provides a plurality of additional functions like cursor positioning using ball-shaped positioning sensor, activating and scrolling menus, drag-lock, clicking. 11. The device of claim 1, wherein two kinds of the front actuators are mounted on and in front of the front surface, whereby bending and unbending clicking functionality is provided thus increasing the number of commands generated by the pointing device and a range of user's customizable options. 12. A pointing device for generating a plurality of computer input signals by a user's hand and control a cursor position on displays, the device being designed to prohibit a wrist stress and keep the wrist joint at safe and comfortable rest thus minimizing tension in the user's hand, avoid pain, fatigue, and computer generated repetitive strain injuries even during protracted periods of continuous use, comprising: (a) a bottom member for carrying a hardware mechanism and positioning the device on an underlying substantially horizontal surface; (b) a housing attached on top of said bottom member upon which to rest a hand; (c) said generally convex housing having a contiguous front, top, rear surface, left and right side surfaces to support a relaxed user's hand and proximal phalanges of fore-, middle, and ring fingers so that the front actuators are activatable by the fingers out of their relaxed position, while the hand itself rests in its relaxed position; (d) means for controlling the cursor position; (e) a plurality of actuators; (f) at least one to three, and preferably two, of said actuators are mounted above the user's fore-, middle or ring finger; (g) the front actuators being designed to be sensitive to the finger moves directed substantially horizontally or vertically upward; (h) the front actuators being designed protected from activation by substantially vertical downward loads. 13. The device of claim 12 further comprising a thumb actuator mounted on the left side, whereby said thumb actuator provides a plurality of functions like cursor positioning using ball-shaped positioning sensor, activating and scrolling menus, drag-lock, clicking. 14. The device of claim 13 further comprising substantially vertical front surface, wherein two kinds of the front actuators are mounted under and above user fingers, whereby bending and unbending clicking functionality is provided thus increasing the number of commands generated by the pointing device and expanding the range of user customizable options. also includes a wireless transmitter for providing communications with any one of the plurality of data processing systems. Each of the plurality of data processing systems includes a wireless receiver for receiving wireless communications from the peripheral input device.
