A Virtual Brain
Influences
• Ideas
• What is a concept?
• What is an Idea?
– A new connection of concepts
– Mind Maps
– Spatial memory
– Associative memory
– Mind Maps
What’s a Virtual Brain?
• Webs
• An Overview
What are they?
• A group of typed Connections
– Eg: The WWW is all the hyperlinks on the internet
• Between
– Concepts
– Objects
– Other Webs
• Non Hierarchical Metadata
• Web Types
• World Wide Web
– Hyperlinks, Bookmarks, History
• Grammar
– Words, Meanings, Thesaurus, Rules and Syntax
• Data Structures
– Scene graphs, Trees
• Content
– Music, Videos, Books
• Knowledge
– Ideas, Concepts, Organisations
• People
– Family, Friends
Why are they needed
What was your first Idea/Thought
Objects can have multiple parents
– Eg: Music
– Things aren’t always linear
– Eg: Web Browsing
• Closer to the way we think
• Information overload
• Well why aren’t there more webs?
• Representations
• Check out some pictures
Web Walking
• A common interface to Webs and the information they connect
• Multiple views of one or more webs
• Differs depending on context
– Input & Output devices
– Task
• Problems
– Getting lost
– Information Overload
What’s a Virtual Brain?
• The Virtual Brain
• An Overview
• The Brain...in one slide
• 100 billion neurons
• 1,000 connections per neuron
• 200 calculations per second per connection
Virtual Brain Components
• Memory
– Short term
– Long term (webs)
• Thought Processes
– Agents
• Modes
– Silent, meeting, relaxing, free time etc
• Interfaces
– Access: Viewing, searching, sharing etc
– Modification: Adding, Changing, deleting etc
– Organising: Metadata management, Associations, Storage locations etc
• Inputs
• Concepts
– Ideas
– Meanings
• Associations
– Influences
• Objects/Data
– Files
– Environmental Conditions
• Organisation
– Layout
– Groupings
– Shortcuts
Capabilities
• Context Engine
• Inference Engine
• Concept comparison
• Memory Access logging
• Total Feedback
• Representations
• Visual
• Spatial
• Uses
• Concept modelling
• Transmitting/Explaining a concept
• Learning and understanding a concept
• Creative Aid
• Brainstorming Tool
A “Smart” PDA….that’s Smart
• What’s a Virtual Brain?
• What is a PDA?
• What does it know?
• Capabilities
• Functions
• Advanced PDA Uses – 3D Interaction
Requirements
– 3DOF sensor
– Accelerometer and/or buttons
• Advanced PDA Uses – Smart Context based interfaces
• Advanced PDA Uses – Idea Tracking System
Automatic association mappings
– Emotion: (Music, GSV, Heart rate)
– Brain state: (Alpha, Beta, Delta Theta)
– Current Task
– Location
– Environmental conditions
– Tasks
– Create Associations
– File away Ideas
– Organise Ideas
– Manage Neural Nets
– Manage Classifications
– What next?
A Vision
– William Gibson (Neuromancer, Johnny Mnemonic)
– Minority Report
– My PhD
– New Media Arts project
• Neurofeedback
• Attention
– Automating data collection using a BCI
And After That?
• Complete Brain Computer Interface
– Nanotechnology
• Will it work?
– Is the pattern and state of neuron connections in our brain truly all that makes up our conscious selves?
– Many people believe firmly that we posses a soul, while some very technical people believe that quantum forces contribute to our awareness.
– Others believe that we are only chemical machines, performing huge numbers of simple calculations that result in an emergent pattern
How Long?
• By the year 2020, your $1,000 personal computer will have the processing power of the human brain - 20 million billion calculations per second
• By 2030, it will take a village of human brains to match a $1,000 computer.
• By 2050, $1,000 worth of computing will equal the processing power of all human brains on earth.
