The device - a mouse 10 is shown - has a generally rounded portion 30 rising from a base 20 and arranged such that in use the user's palm and wrist are held at a mid-position between pronation and supination. The hand may be outstretched (ie not clenched) with the little finger and the pad of flesh at the side of the hand resting on the base 20. Side walls 40, 50 may be provided to support the little finger, wrist and/or thumb. An additional wrist or arm support may also be provided. The rounded portion 30 may carry one or more input means, eg wheel 61 and switches 62, 63. Part of the rounded portion may contain data storage means, eg a flash RAM memory, and be detachable. The device increases comfort and reduces fatigue, pain and injury.
