Virtual Reality Application Center
Slide2Currently, there exists no inexpensive system that is able to
accurately localize object in
three-dimensional
space.
We are concerned with small scale and high accuracy, unlike GPS.Such a system could be used as an input device/controller to a computer system. It could be used for virtual reality systems, touch tables, or a “Minority Report”-style UI.Our goal is to create such a system, capable of tracking multiple objects.
Problem Statement
Slide3Design and build a 3D indoor positioning system (IPS) for VRAC applications such as multi-touch table or touch wall. The end product is to provide fingertip tracking with 1 cm accuracy.
Two main components: IPS Device: Worn on fingertips, or embedded in a glove IPS Infrastructure: Detects location of IPS Devices
Objective
Slide4Conceptual System Diagram
Slide5Functional Decomposition (Modules)Multiple, reproducible tracking devicesTracking
methodsReceived signal strengthInfrared beacons and cameras
Ultrasonic
emitters
Hybrid (Accelerometers and gyros paired with localization)
A
minimum of 15Hz refresh rate on position
Slide6Provide position updates with 1 cm accuracy within a 2 m x 2 m x 2 m region indoors
Give position updates 15 times per second
Display position in a graphical interface
Support as many simultaneous devices as possible
Functional Requirements
Slide7Small, lightweight device
Durable device
Device with long battery life (a few weeks)
Easy to set up infrastructure
Reproducible devices with consistent quality
Non-Functional Requirements
Slide8Small device size limits choice of technology
Need for battery life forces much of the work to be done by the infrastructure
Want the system to be as non-intrusive as possible (no annoying beeps or lights)
In order to distinguish devices, some part of the device must be distinguishable to infrastructure
Constraints
Slide9Tenative Timeline
Slide10Finding the right technology for the task, need to do strong research and prototyping
Research needs to be completed on schedule so the project does not fall behind
Requirements are challenging and aiming for them could lead to coming up short, need to design the system such that there is room to give
