Abstract: This document describes imaging and visualization systems in which the intent of a group of users in a shared space is determined and acted upon. In one aspect, a method includes identifying, for a group of users in a shared virtual space, a respective objective for each of two or more of the users in the group of users. For each of the two or more users, a determination is made, based on inputs from multiple sensors having different input modalities, a respective intent of the user. At least a portion of the multiple sensors are sensors of a device of the user that enables the user to participate in the shared virtual space. A determination is made, based on the respective intent, whether the user is performing the respective objective for the user. Output data is generated and provided based on the respective objectives respective intents.

Abstract: A light emitting user input device can include a touch sensitive portion configured to accept user input (e.g., from a user's thumb) and a light emitting portion configured to output a light pattern. The light pattern can be used to assist the user in interacting with the user input device. Examples include emulating a multi-degree-of-freedom controller, indicating scrolling or swiping actions, indicating presence of objects nearby the device, indicating receipt of notifications, assisting pairing the user input device with another device, or assisting calibrating the user input device. The light emitting user input device can be used to provide user input to a wearable device, such as, e.g., a head mounted display device.

Abstract: Augmented and virtual reality display systems increase viewer comfort by reducing viewer exposure to virtual content that causes undesirable accommodation-vergence mismatches (AVM). The display systems limit displaying content that exceeds an accommodation-vergence mismatch threshold, which may define a volume around the viewer. The volume may be subdivided into two or more zones, including an innermost loss-of-fusion zone (LoF) in which no content is displayed, and one or more outer AVM zones in which the displaying of content may be stopped, or clipped, under certain conditions. For example, content may be clipped if the viewer is verging within an AVM zone and if the content is displayed within the AVM zone for more than a threshold duration. A further possible condition for clipping content is that the user is verging on that content.
