VirtualBricks

10th Jan, 2019

VirtualBricks is a LEGO-based toolkit to enable easy, need-based construction of passive haptics for VR. It comprises of a set of modules that provide pose detection, novel single- axis manipulation input, and a range of other interactive functionalities. Modelled as LEGO bricks, these modules can be combined with simple LEGO bricks to create physical proxies for a variety of virtual objects, having different shapes and supporting different interactions — like a fishing rod or a slingshot. We developed a VR Integration software package to faciliate easy integration with Unity. This work was (conditionally) accepted at CHI 2019. Camera ready version can be found here.
