The company holds worldwide patents on a unique technology that delivers a one-of-a-kind immersive experience—without the aid of glasses or other devices. Markets and industries that can most benefit from Alioscopy technology include: point-of-sale kiosks (POS), digital signage, media and entertainment, mobile communications and games, automotive, architecture, engineering and construction (AEC) visualization, and medical, government and military.
Alioscopy Technology Overview
In everyday life, we perceive depth in our environment thanks to different sets of information processed by our brain. Most of us see with two eyes and binocular vision is, of course, essential. It feeds our brain at all time with slightly offset views of a scene: the greater the disparity, the closer the object. At the same time, converging nearby or far away gives our brain hints of distances.
There are many monocular parameters though, simultaneously taken into account by our brain. Perspective is one of them. Painters have used the perspective since the Renaissance to represent depth in a landscape. Perspective lines, along with the size of objects, are indications of depth. Occlusion is another one and our brain knows that objects hiding others are necessarily placed in front. Reflections and shadows, among others, also contribute to the global sensation.
When watching television, both eyes see the same view. There is no sensation of depth except for perspective. 3D television and 3D cinema, on the other hand, produce a real sensation of depth. They require special stereoscopic films, combining two views, one for the left and one for the right eye. Viewers wearing special glasses will only see the left view with the left eye and the right view with the right eye. This recreates a binocular effect and produces a true sensation of depth.
Alioscopy displays are called auto-stereoscopic. They produce the same sensation of depth as described above, but without needing cumbersome eyewear. They are instead equipped with an array of lenticular lenses, casting different images onto each eye. Instead of combining two views, Alioscopy films actually multiplex 8 offset views of a scene. This is why Alioscopy displays are also called multiview displays.
