Paper reading: SDM-NET & New tools for 3D deep learning

1.This week I found a paper, SDM-NET: Deep Generative Network for Structured Deformable Mesh. Their main idea is to decompose a 3D object into parts. And each part can be deformed from a homeomorphic simple object. Their network can also learn the support and symmetry information from the input. The part structures and geometries are…

Tested a 15m Walkway

This week I setup a 15-meter walkway in the lab for the obstacle experiment in walking paradigm. I chose to use Vive pro with a wireless adapter to accomplish a wireless VR experience. Compared with Oculus Quest, the wireless Vive pro is much heavier, and it is still constrained by the coverage of Lighthouses and…

A parallel world

This last week or so I’ve been building a parallel world. I measured all of the sizes in a section of our lab — walls, floors, tables, and so forth. Then I built a computer graphic copy of that world, matching the real thing down to the centimeter. I can walk around in my parallel…

Virtual Obstacles in Gait

A few weeks earlier, I talked about two papers I read regarding gait balance when fixed or suddenly appeared obstacles are involved. The papers are Age Effects on Strategies Used to Avoid Obstacles, and Anxiety-mediated gait adaptations reduce errors of obstacle negotiation among younger and older adults: Implications for fall risk. We have been looking for protocols and…

Distributed Systems and Virtual Reality

I’ve been thinking a lot lately about networking and how we use it for our co-located immersive experiences. What are the pressing questions as one designs such a system for shared experiences like these? In order to deliver these compelling experiences that exceed the capabilities of stand-alone, inside-out tracked devices such as the recent Oculus…
