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.

Position-determining input device

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.
