Emoti – Colour ExplorationBy Nick Marshall

Summary

Emoti – Colour Exploration is a new way to explore Plymouth as a Digital City.

Using Social Media photograph uploads, emoti – colour exploration analyses sets of photos from different areas of Plymouth. Algorithms are applied to each set of photos and a new

emotive colour is created, specific for each space. This information is then passed to a GPS-enabled beacon object. Users hold this object as they navigate through Plymouth following

the colour and pattern changes.

Project Aims

• Show Plymouth as a Digital City using a variety of welcoming media

• Explore aspects of Social Media and Ubiquitous Computing

• Change the way People use the space

Approach

• What Information can I get from Plymouth?

• How can I use this information to change people’s perception of and behaviour in the city?

• How can I establish a dialogue between people and their space from their own media?

• What is the best way to feed this information back to the user?

Ideas!

• Emotive links to an object

• Emotion inspired by visualisation – colour, light, sound

• Social media and geoLocative data feeds

Prototype

• Using twitter feeds and word analysis to extract emotive data from people about Plymouth.

• Using arduino, bright LED and a GPS unit as an object for the user.

• Different colour pulsing and colour hue changes in real-time

Problems

• Plymouthians don’t know how to tweet?

• Available API’s such as twitter4j contain bugs since new twitter API changes

• Arduino memory and battery life

New way forward

• Panoramio – social media image hub

• Bigger bootloader for arduino and code tidying

• Image analysis of photos to influence LED values of specific areas

Algorithms

Image Algorithms and Analysis
