  • Next we pry out this hunk of ... stuff, which turns out to be an earpiece speaker, mic, ambient light sensor (AMS TMD3702VC), and the Soli chip, for interpreting your gestures using the power of radar.

  • Google calls this implementation of its in-house Project Soli Motion Sense.

  • Although radar technology has been in use for a long time and seems simple enough on paper, we're at a loss as to how Google stuffed the entire system into a tiny featureless rectangle with no moving parts.

  • Motion Sense works by emitting precisely tuned waves of electromagnetic energy. When those waves bounce off of something (like your hand), some of them reflect back to the antenna.

  • The Soli chip then studies the reflected waves and analyzes their time delay, frequency shift, and other data to learn the characteristics of the object that reflected them—how big it is, how fast it's moving, in which direction, etc.

  • Soli then runs that data against its known gesture database to determine what action, if any, needs to be performed in the OS.

  • TL;DR: magic rectangle knows your every move.

Puis nous retirons ce ... truc, qui s'avère être un haut-parleur interne, un microphone, un capteur de luminosité ambiante et la puce Soli qui sert à interpréter vos gestes en utilisant le pouvoir du radar.

Google appelle cette mise en place de son propre Project Soli Motion Sense.

Bien que la technologie du radar est utilisée depuis longtemps et semble être assez simple sur le papier, nous peinons à comprendre comment Google a réussi à tasser le système entier dans un rectangle minuscule sans éléments mobiles.

Motion Sense fonctionne en émettant des ondes d'énergie électromagnétique réglées avec précision. Lorsque ces ondes sont renvoyées par un objet (par exemple votre main) quelques unes d'entre elles reflètent vers l'antenne.

Puis la puce Soli étudie les ondes reflétées et analyse leur temps de retard, le décalage de fréquence et autres données pour apprendre les propriétés de l'objet qui les a reflété, sa taille, la vitesse à laquelle il bouge, dans quelle direction, etc.

Puis Soli fait passer ces données dans sa base de donnés de gestes connus pour déterminer quelle action, si du tout, doit être effectuée au niveau du système d'exploitation.

TL;DR : le rectangle magique connait chacun de vos gestes.
