Appl. No.:

12/817662

Inventors:

Brent Charles Allen - Bothell WA, US
Joerg Raymond Brown - Woodinville WA, US
Neil A. Brench - Redmond WA, US

Assignee:

MICROSOFT CORPORATION - Redmond WA

International Classification:

G06F 9/46

US Classification:

718103

Abstract:

Various embodiments can control access to a computing resource (e.g., a memory resource) by detecting that a high priority activity is accessing the resource and preventing a lower priority activity from accessing the resource. The lower priority activity can be allowed access to the resource after the high priority activity is finished accessing the resource. Various embodiments enable memory operations to be mapped to account for changes in data ordering that can occur when a lower priority activity is suppressed. For example, when an activity requests that data be written to a logical memory region, a mapping is created that maps the logical memory region to a physical memory region. The data can then be written to the physical memory region.

Abstract:

In embodiments of a camera-based input device, the input device includes an inertial measurement unit that collects motion data associated with velocity and acceleration of the input device in an environment, such as in three-dimensional (3D) space. The input device also includes at least two visual light cameras that capture images of the environment. A positioning application is implemented to receive the motion data from the inertial measurement unit, and receive the images of the environment from the at least two visual light cameras. The positioning application can then determine positions of the input device based on the motion data and the images correlated with a map of the environment, and track a motion of the input device in the environment based on the determined positions of the input device.

Abstract:

In embodiments of augmenting a moveable entity with a hologram, an alternate reality device includes a tracking system that can recognize an entity in an environment and track movement of the entity in the environment. The alternate reality device can also include a detection algorithm implemented to identify the entity recognized by the tracking system based on identifiable characteristics of the entity. A hologram positioning application is implemented to receive motion data from the tracking system, receive entity characteristic data from the detection algorithm, and determine a position and an orientation of the entity in the environment based on the motion data and the entity characteristic data. The hologram positioning application can then generate a hologram that appears associated with the entity as the entity moves in the environment.
