"Techmedia's cordless 3DZoneMaster is a mouse, a joystick and an ergonomic work of art that looks good enough just sitting on the computer table.
But in this case, beauty is more than skin deep. The 3DZoneMaster has a nice heft to it and its curve fits comfortably in either hand. On top, the thumb easily can access the three buttons and the "top hat" joystick button for 360-degree movement. The index finger fits over the trigger and the third finger rests on a second trigger that's used for centering. All of the buttons and the index trigger are programmable.
Instead of using infrared signals like most remote controls, 3DZoneMaster uses ultrasound. The receiver, which plugs into the PC's serial port, is a right-angle frame that fits over one corner of the screen. As you move your hand, you move in the respective direction on the screen. Raise the 3DZoneMaster, you go up, move toward the screen and you move forward, etc. This is a perfect way to navigate those first-person perspective games such as Doom and Quake. The trigger fires weapons and the buttons do whatever you set them up to do, such as jumping or kneeling.
The other function lets you use the 3DZoneMaster as you would a mouse. Just move it through the air and the mouse cursor goes in the same direction. Click with the trigger or any button of choice. If you have a second serial or mouse port, you can use either or both devices at the same time.
I played the included games as well as several from my own collection and found the 3DZoneMaster to be very responsive. Techmedia claims it will work with all mouse-compatible games. I still prefer to navigate the desktop with my mouse so the two-port support is a nice feature. The 3DZoneMaster requires a nine-volt battery, Direct X and a serial port." ~Craig Crossman, Washington Post ("A MOUSE THAT CAN MAKE LIKE A JOYSTICK")
