    摘要: An optical interactive panel includes a cladding layer, a first waveguide array, a second waveguide array, a first set of image sensor, and a second set of image sensor. The cladding layer has a first index of refraction. The first waveguide array has first waveguide channels formed on the cladding layer, wherein the first waveguide channels have a second index of refraction less than the first index of refraction, and extending at a first direction. The second waveguide array has second waveguide channels, formed on the cladding layer and extending at a second direction. The first set of image sensor detects a first set of light signals from the first waveguide channels to determine a first-direction location. The second set of image sensor detects a second set of light signals from the second waveguide channels to determine a second-direction location.
