Thought-controlled computing

US technology company Emotiv Systems has developed a headset that allows a user to manipulate elements on a computer screen with only the power of thoughts, expressions and emotions.

Hailed as a revolution in human-computer interaction, the lightweight, wireless Emotiv EPOC neuroheadset, priced at $299 (£148), features sensors that detect conscious thoughts, expressions and non-conscious emotions based on electrical signals around the brain.

‘When integrated into games, virtual worlds and other simulated environments, this technology will have a profound impact on the user’s experience,’ claims Nam Do, chief executive of Emotiv systems.

The non-invasive headset registers the interaction of neurons in the brain when an electrical impulse is emitted, meaning that it can recognise certain cognitive actions to move on-screen elements. The EPOC can also detect various emotions including excitement and frustration, and recognises facial expressions such as a smile or a grimace, while a gyroscope allows the camera or cursor to be controlled by
head movement.

IBM says it intends to explore how the headset could be used for researching other applications including virtual training and simulation platforms for business. Paul Ledak, vice president of IBM Digital Convergence, comments: ‘As interactions in virtual environments become more complex, mice and keyboards alone may soon be inadequate.’
