Functional vocabulary: an issue for Emotiv and Brain-Computer Interfaces

The Emotiv system is a EEG headset designed for the development of  brain-computer interfaces.  It uses 12 dry electrodes (i.e. no gel necessary), communicates wirelessly with a PC and comes with a range of development software to create applications and interfaces.  If you watch this 10min video from TEDGlobal, you get a good overview of [...]

Better living through affective computing

I recently read a paper by Rosalind Picard entitled “emotion research for the people, by the people.”  In this article, Prof. Picard has some fun contrasting engineering and psychological perspectives on the measurement of emotion.  Perhaps I’m being defensive but she seemed to have more fun poking fun at the psychologists than the engineers, but [...]

iBrain

I just watched a TEDMED talk about the iBrain device via this link on the excellent Medgadget resource.  The iBrain is a single-channel EEG recording collected via ‘dry’ electrodes where the data is stored in a conventional handheld device such as a cellphone.  In my opinion, the clever part of this technology is the application [...]

This is your brain giving up

Like a lot of people, I came to the area of physiological computing via affective computing.  The early work I read placed enormous emphasis on how systems may distinguish different categories of emotion, e.g. frustration vs. happiness.  This is important for some applications, but most of all I was interested in user states that related [...]

What’s in a name?

I attended a workshop earlier this year entitled aBCI (affective Brain Computer Interfaces) as part of the ACII conference in Amsterdam.  In the evening we discussed what we should call this area of research on systems that use real-time psychophysiology as an input to a computing system.  I’ve always called it ‘Physiological Computing’ but some [...]

Emotional HCI

Just read a very interesting and provocative paper entitled “How emotion is made and measured” by Kirsten Boehner and colleagues.  The paper provides a counter-argument to the perspective that emotion should be measured/quantified/objectified in HCI and used as part of an input to an affective computing system or evaluation methodology.  Instead they propose that emotion [...]

Neurofeedback in Education

FutureLab have published a discussion paper entitled “Neurofeedback: is there a potential for use in education?”  It’s interesting to read a report devoted to the practical uses of neurofeedback for non-clinical populations.  In short, the report covers definitions of neurofeedback & example systems (including EEG-based games like Mindball and MindFlex) as background.  Then, three potential [...]
