In some examples, an apparatus includes a memory storing computer executable instructions for implementing a spatially aware computing scheme; and a processor coupled to the memory and configured to execute the executable instructions. Executing the executable instructions causes the processor to access a spatial augmentation layer (SAL) that includes augmented reality (AR) elements placed into an AR environment for a physical environment proximate to the apparatus, and display the AR elements on a display screen communicatively coupled to the apparatus, wherein at least some of the AR elements are elements placed into the AR environment by a user other than a user of the apparatus.
