Low-Latency Rendering With Dataflow Architectures

Realistic low-latency mobile AR rendering

When designing a system for mobile augmented reality, problems to be tackled concern tracking, rendering performance, end-to-end latency, battery usage, and communication bandwidth of the mobile platform. We developed an integral solution covering all these aspects, while still being manageable from the application's point of view. In this paper we outline the global layout of our system, and d...

Low latency rendering for mobile augmented reality

Mobile augmented reality requires accurately alignment of virtual information with objects visible in the real world. We describe a system for mobile communications to be developed to meet these strict alignment criteria using a combination of computer vision and inertial tracking and image-based rendering techniques.

Distributed Low-Latency Rendering for Mobile AR

Wearable augmented reality (AR) can help the task of a user by adding virtual objects to his view on the real world. To save power in the mobile unit, rendering can be offloaded to the backbone as much as possible. However, because of low latency requirements, images for mobile AR can not be rendered completely in the backbone. We developed a system capable of end-to-end latencies of 10ms, with...

Dataflow Architectures for GALS

In Kahn process network (KPN), the processes (nodes) communicate by unbounded unidirectional FIFO channels (arcs), with the property of non-blocking writes and blocking reads on the channels. KPN provides a semantic model of computation, where a computation can be expressed as a set of asynchronously communicating processes. However, the unbounded FIFO based asynchrony is not realizable in prac...
