The Inventory system (tools selector) is a 3D UI element that provides the user with a tool that is relevant to their experience.
Prototype in Unreal Engine
Need analysis
Currently, in large tabletop or room-scale experiences, the user must go back and forth frequently to grab the tool from its spawning origin. Frequent back & forth causes cognitive load and is intrusive; therefore, the user must have the tools they require in the step to be spawned near them. The user may have multiple working stations where one tool is used, and they must currently carry the tool with them while holding the grip button.
