Project Presentation

CS6022Colm Walsh

Original Idea

•Interactive space•Designed for dancers/stage performers•Body movements generate visual and audio feedback that can be controlled by user

What is it about?

Social Interaction

What is it about?

Social InteractionInteraction with Public Space

What is it about?

Social InteractionInteraction with Public SpaceIdea of Personal/Intimate Space

Why?

•Smart Phone culture•An “App for Everything”•Reasons to interact increasingly less•Everyone in their own little world

Why?

The Bubble Effect

What do I want to do?

•Burst the “bubble”•Encourage interaction, collaboration and play•In a public space

Where?

•A Public Space•Consistent Flow of People•Area of Congregation

Who is it for?

•In a public space, any member of the public is a potential user•In particular places,•Bus station, hotel lobby: people waiting•Pedestrianised street, square: people in transit

Social Interactions

Social Interactions

•Strategic Complimentaries: “occur when the marginal utility to one person of undertaking an action is increasing with the average amount of the action taken by his peers.” – Scheinkman, J. A.

Social Interactions

•Critical Mass Model, Schelling, T.•Some individuals will always do the activity•Others will do it if a high enough fraction of the population is engaged in the action•Still others may never do it

Social Interactions

•Social Learning Theory, Bandura, A.•Attention•Retention•Reproduction•Motivation

•Reciprocal Determinism

The Pleasures of Play

•Costello, B., Edmonds, E.•A framework developed as a synthesis of the ideas of six theorists

The Pleasures of Play

Technology

Computer Vision Techniques Using Processing

Technology

Computer Vision Techniques Using Processing

1. Detecting Motion•Brightness and colour of pixels are compared, frame-to-frame•Difference = measure of amount of movement•Depends on relatively stable lighting

Technology

Computer Vision Techniques Using Processing

2. Detecting Presence•Background subtraction•Background of empty scene stored•Difference in colour represents movement•Sensitive to changes in lighting conditions

Technology

Computer Vision Techniques Using Processing

3. Brightness Thresholding Detection•Ensure objects of interest are considerably darker/lighter than surroundings•Use Backlighting•Pixel’s brightness compared to threshold value

Technology

Computer Vision Techniques ADVANCED

1. Infrared illumination2. Retroflective lighting materials3. Telecentric lens

Technology

Video and Audio Control

• Pure Data and PD GEM (Graphics Environment for Multimedia)

• VVVV: can handle large media environments with physical interfaces, real-time motion graphics, audio and video that can interact with many users simultaneously.

Technology

Video and Audio Control

• SWARM simulation: provides patterns of motion that are apparently random, but when viewed as a whole exhibit a visual coherence

• Moving object is treated as a force field (gravitational) – centre of the swarm

• DEMO

Next Steps
