Assessment of relative positioning technologies for compositional tangible user interfaces

Objective

This assessment project will investigate ad hoc relative positioning of physical objects as enabling technology for compositional tangible user interfaces. The project will specifically investigate enabling technologies to measure relative distance and relative orientation autonomously, e.g. independent of infrastructure in the environment. The assessment will address technical feasibility, acquisition speed, scalability, robustness, deployment factors and application range.

OBJECTIVES
The general aim of this project is to investigate enabling technologies that can be employed to measure relative distance and angle between tangible user interface objects in the absence of infrastructure. The particular objectives are:
I. To assess technical feasibility and acquisition speed;
II. To assess scalability, e.g. overall acquisition time as function of number of components;
III. To assess robustness by identifying environmental conditions that negatively influences performance;
IV. To assess cost vs. gain for technology alternatives;
V. To assess applicability by building and evaluating application demonstrators.

DESCRIPTION OF WORK
The general approach the project will adopt is to build prototypes to explore the full design potential of the technology and to uncover both technical and use-related issues that may not be obvious. The actual work breaks down into four distinct packages:
1. 1G Prototype: selection of orientation and distance measuring technology, selection/implementation of communication protocol, implementation of 4 tangible objects, idea generation for compositional tangible interfaces, implementation of an application demonstrator;
2. Analysis and evaluation of enabling technologies: design and build experimental set-ups, assess performance with respect to the assessment objectives;
3. 2G Prototype: Redesign of position, orientation and communication technology, system implementation with 16 objects, and assessment of scalability;%4L. Usage scenarios and deployment analysis: scenario development, analysis of new interface concept enabled by relative positioning, analysis of deployment factors, and implementation of a showcase application.
