Lazyweb Request: Heartbeat Sensor

Dear Lazyweb:

Does anyone know where I can get a reliable, cost effective heartbeat sensor? Ideally it would be something small that would not be cumbersome like the Garmin ForeRunner, and wouldn't have to go on my fingers to get a pulse. Even if that's all you know about, please share with me, and the rest of the intarweb.


So I guess my comment system isn't working anymore unless you're a spammer. For the meantime, please email me at igargoyle nospamplease at

My dr was impressed with accuracy
requires a band (not pictured) worn around the chest....

Virtual Walking with Brain Signals


Using brain signals, researchers in Austria and London have been able to use the brain signals of people thinking about walking in order to control virtual reality interfaces, as well as potentially control wheelchairs and eventually exoskeletons.

Researchers from Graz University of Technology in Austria, University College of London in England, Guger Technologies OEG in Austria and the University of Graz in Austria have expanded the amount of control available via external electrodes with a means of detecting changes in brain signals when users imagine moving their feet and translating the effect into walking motion within a virtual reality environment.

The system is distinguishes brain signals produced by thinking about different types of movements, including right hand, left hand, foot and tongue, and converts the information to control signals. Three test subjects were able to move forward through an immersive virtual street scene by imagining walking.

This type of interface promises to enable those who are disabled, and could eventually give and people whose hands and voices are otherwise occupied another way to assess computers.

In a related development, members of the same research team have developed a portable brain-computer interface for use in virtual environments. The battery-powered interface, which includes a diskless Pocket PC, makes it possible for people to physically move while using brain signal control.

I'm not impared, but this is major news in my opinion- if only to improve the immersion factor of playing first person shooters.

NASA's BioBlackBox

bioblackbox.jpgNASA's been developing, again, this time a biometric black box; something I think many people would benefit from. The device is said to capture "biological data, like changes in heart rate, the amount of oxygen in the blood stream, how the wearer is moving ... and much more.". Hopefully development like this will spur on the health community to make better biometric devices. Speaking of which, I think I'm going to go to McFranchise soon to get one of those pedometers they're giving away with salads.
