DESCRIPTION:Angular information is applied across domains such as navigati
 on\, virtual and augmented reality\, and robotics to tackle research probl
 ems related to directions and orientations. It can be encoded into polariz
 ation to reveal hidden content\, and it can also be encoded into parallax 
 to track an object with high accuracy. This talk starts from exploring the
  potential of polarization and how angular information plays a crucial rol
 e in uncovering hidden phenomena\, along with real-world applications. It 
 then introduces two stable and precise visual methods for measuring direct
 ional information. The first approach was to design a passive marker\, Moi
 réTag\, that exploited the moiré effect to encode high accuracy angular 
 information into moiré patterns generated by periodic binary structures p
 rinted on both sides of a glass wafer. We then extended the continuous tra
 cking approach into a discrete fashion by introducing a scannable QR-desig
 n marker. High frequency information encoded in the QR-Tag can be reliably
  decoded by a phone camera from different positions at a certain distance.
