Keep hands together to avoid injuries that may occur when the hand is outside the comfort zone using a computer mouse. The Trackbar Emotion Computer Mouse is a preemptive strike against carpal tunnel syndrome and repetitive stress injuries. The central pointing device keeps the users hands and arms in a naturally centered position while working, thereby reducing strain. Its portable, plug and play for both MAC and PC, has six buttons and a built in microphone so you can replace click commands with voice commands.
