Mobile Monitors and Apps for Physiological Computing

I always harbored two assumptions about the development of physiological computing systems that have only become apparent (to me at least) as technological innovation seems to contradict them.  First of all, I thought nascent forms of physiological computing systems would be developed for desktop system where the user stays in a stationary and more-or-less sedentary [...]

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 [...]

In the shadow of the polygraph

I was reading this short article in The Guardian today about the failure of polygraph technologies (including fMRI versions and voice analysis) to deliver data that was sufficiently robust to be admissible in court as evidence.  Several points made in the article prompted a thought that the development of physiological computing technologies, to some extent, [...]

Heart Chamber Orchestra

I came across this article about the Heart Chamber Orchestra on the Wired site last week.  The Orchestra are a group of musicians who wear ECG monitors whilst they play – the signals from the ECG feed directly into laptops and adapts the musical scores played directly and in real-time.  They also have some nice [...]

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 [...]
