It will be appreciated, however, that in some cases it may be desired to move the cursor towards the selected character as well as, or instead of, moving the selected character towards the cursor. It will also be appreciated that the circle display could display other images rather than the characters of a keyboard, for example a plurality of individually-selectable icons, or a plurality of individually-selectable objects in a computer game.
  • Fig. 12 illustrates an arrangement wherein a hand-held unit 90, such as described above, also transmits via a wireless link 91, to another unit 92 for controlling the display 93 thereon, e.g., the movement of a cursor 94 thereon, in accordance with the pitch and roll movement of unit 90.

Abstract

Processeur de données portable, pouvant être tenu dans une main et être orienté suivant différentes positions dans l'espace (lettres X et Y), comprenant un écran d'affichage (numéro 2) pouvant être visualisé par l'utilisateur et une microcommande présentant deux gradomètres micro-usinés, transistorisés, montés perpendiculairement l'un par rapport à l'autre, en vue de mesurer les inclinaisons des axes X et Y de l'écran par rapport à la verticale, afin de régler l'affichage sur l'écran conformément à l'inclinaison mesurée. On décrit une pluralité d'applications de ce processeur de données, telles que téléphone mobile, assistant numérique personnel, jeu informatique, détecteur de position du corps, utilisé notamment pour détecter l'assoupissement d'un conducteur de véhicule, et clavier sphérique dynamique facilitant la sélection d'un code.
