Translating Interactions on a Two-Dimensional Interface to an Artificial Reality Experience
Many users access artificial reality (XR) experiences through their mobile phones. However, it is difficult to translate XR experiences to a two-dimensional (2D) screen in a way that feels intuitive and natural. Thus, the technology can map an interaction plane in a three-dimensional (3D) scene to the 2D screen with as many affordances as possible, even if the plane is not parallel to the mobile phone. The plane can be a fixed surface or a dynamically changeable surface through which the user sends inputs through the 2D screen. The mapping of the plane to the 2D screen can control interaction with a virtual object on the interaction plane in the XR environment, enabling parity between the same experience on XR and non-XR interfaces.

Digital pixel sensor having extended dynamic range
In one example, an apparatus comprises: a photodiode configured to generate a charge in response to light within an exposure period, a charge sensing unit configured to accumulate at least a part of the charge as an overflow charge, a quantizer, and a controller configured to: within a first time within the exposure period, control the quantizer to perform a first quantization operation to quantize the overflow charge accumulated at the charge sensing unit to generate a first measurement output; within a second time after the first time, and within the exposure period, control the quantizer to perform a second quantization operation to quantize the overflow charge accumulated at the charge sensing unit to generate a second measurement output; and generate a digital output to represent an intensity of the light based on at least one of the first measurement output or the second measurement output.
H04N 25/59 - Commande de la gamme dynamique en commandant la quantité de charge stockable dans le pixel, p. ex. en modifiant le rapport de conversion de charge de la capacité du nœud flottant
H04N 25/60 - Traitement du bruit, p.ex. détection, correction, réduction ou élimination du bruit
