A much wider roll than other roll-using devices available today allows for precise cursor motion with considerably less manual effort and thus greater comfort and a faster learning curve.

Highly sensitive, large buttons to operate - most traditional mice require up to 3 times the force! The latest studies indicate that using less force helps prevent and rehabilitate suffering.

Carefully analyzed surfaces are well suited to users who compute five or more hours daily: maximum comfort is achieved with materials that are non-sweat-promoting, smooth and soft.

Buttons can be programmed, using a software that can be downloaded free of charge, to give the user to the critical advantage of speeding up repetitive processes and greatly reducing "mousing" strain on hand and arm muscles.

Dual sensors - The only ergonomic computer mouse with dual optical sensors; 2 x 1000 dpi sensors create unbeatable performance.

Microphone - Trackbar Emotion has a built in microphone, enabling the user to use voice control software and thus replace hand movements with spoken commands
