Acuité visuelle


On annonçait hier, en grande pompe comme toujours, la sortie du iPad 2. Objet technologique suscitant la convoitise, cette bébelle se vendra comme des petits pains chauds prochainement. Mais côté gadget, je vous propose quelque chose d’encore plus cool : un portable contrôler par les yeux!

Le prototype du portable PC Thinkpad, capable de suivre et de transposer les mouvements oculaires dans le rôle de souris ou de pavé tactile, a été développé grâce à l'expertise du Suédois Tobii. La technologie permettant de suivre la direction du regard n'est pas chose nouvelle, mais les entreprises Tobii et Lenovo souhaitent désormais l'utiliser pour faciliter l'interaction entre l'ordinateur et l'humain.

Pour ce faire, il ne suffit que d'installer quelques capteurs infrarouges dans l'ordinateur et de concevoir des logiciels favorisant la communication entre l'homme et la machine. La force de ThinkPad est qu'il intègre ces éléments, plutôt que d'exiger que son usager ait à porter ou utiliser un accessoire.

Lors du CeBIT (Centrum fur Büroautomation, Informationstechnologie und Telekommunikation) de Hanovre, Tobii a même promis un portable pour le grand public d'ici quelques années, qui bénéficierait de la technologie eye tracking pour en faciliter le contrôle.

D'ailleurs, Tobii a même présenté en grande première son prototype de portable, développé grâce à la collaboration de Lenovo. Après un processus de calibration, les visiteurs ont pu l'essayer et tenter de sélectionner ou de déplacer des objets sur l'écran ou de faire défiler un texte au fur et à mesure de la progression de sa lecture.

Bien que Tobii vise à exploiter son expertise en «eye tracking» dans le secteur commercial, comme le marketing ou la publicité, plusieurs autres applications sont considérées. Par exemple, en médecine pour assister un chirurgien, en sécurité routière en détectant les conducteurs fatigués aux yeux se refermant, ou encore pour le secteur militaire.

Chords introduce harmony into music and it is the effects created by chords that produce the inspiration behind so much music and make it so satisfying both to listen to and to play.

Instead, focus on a single thing or just a couple of things,
and try not to move forward until you have reached those goals.

protection from various hazards such as my gravel road, and unlike
some competitors they are not prone to smelling bad. A really great
