- the KB should be comfortably fit in each hand
{like DataHand},
- cordless
- small and light {as possible},
- with an integrated 3D-space-movement controlled mouse
{without leaving the keys,{like the Twiddler, see homepage: [2] },},
{but {unlike the Twiddler}, for each hand},
- no need for costly armchair integration
{what is a good idea until now},
- both hands and arms should have maximal freedom
{like using a castanet},
{see: [1] for a picture of this musical instrument:-},
