Introduction

The handshake position of the wrist when using the Evoluent 4 Bluetooth enables working in a comfortable natural position.

The handshake position of vertical mice keeps the wrist from bending as much to the side while the forearm also turns inward to a lesser degree (Schmid, et al., 2015). This means that muscle activity in the forearm is less than it would be when using a conventional mouse (Quemelo & Vieira, 2013).

Research has shown that the use of a vertical joystick mouse ensures a faster recovery from forearm, wrist and hand complaints (Aarås, et al., 2001).

- Ergonomic: supports your hand in a fully upright neutral handshake position that eliminates forearm twisting
- Precise: true optical resolution sensor moves the pointer quickly to reduce hand movements, with short habituation time
- Version 4 improved shape: better thumb and finger support
