Novel Interactine
CMT3321 – Week 19 – Sample Exam Question
Question
(a) Describe the key features of Tangible User Interfaces, comparing and contrasting them with multi-touch interactive surfaces.
[ 10 marks ]
(b) Consider the following scenario:
The Tangible Disaster Simulation System is a collaborative tool for planning disaster measures based on simulations of disasters and responses such as evacuation and the actions of emergency services.
Users can define parameters of a disaster (such as its scale and severity) and of the emergency measures (such as the location and capacity of shelters or the effectiveness of emergency services). The system will be able to simulate the progress of a disaster situation and present information about likely outcomes.
Describe a design concept for a tangible interactive system that will facilitate such collaborative, interactive exploration of the consequences of disaster situations.
In your description, explain, with diagrams if helpful, the elements of your design, interactive technologies that will be used and the tasks to be supported, including appropriate justification.
[ 25 marks ]
(c) Describe a plan for how an evaluation of such a design could be conducted. As part of your plan, you should discuss what the evaluation will be trying to discover, what kinds of prototypes would be appropriate, what methods will be applied (and why), how those methods will be carried out, and so on.
[ 15 marks ]
Answer
Part (a) [ 10 marks ] Key features of TUIs: * Objects are tangible representations * Computational coupling of tangible representations and digital information and processes * Embodiment mechanisms for interactive control * Perceptual coupling of tangible representations to dynamic digital representationsSome other common, but not essential features are interaction in a large space, shared or sharable multi-user interaction, reliance on user’s understanding of the physical world, etc.Multi-touch
