Abstract: Systems, methods, and computer program products that render a partial boundary of a mixed reality virtual space are disclosed. One system includes an apparatus including a processor and a memory coupled to the processor. The memory includes instructions executable by the processor to cause the apparatus to display a virtual object proximate to a boundary of a virtual space within a mixed reality environment and render an indicator representing the boundary over the virtual object in response to a user approaching the boundary. Here, the indicator is not rendered in the mixed reality environment beyond being rendered over the virtual object in response to the user approaching the boundary. Methods and computer program products that include and/or perform the operations and/or functions of the system, apparatus, and/or processor are also disclosed.
