O’Reilly author Alasdair Allan (Learning iPhone Programming and the upcoming Programming iPhone Sensors) talked about using the OpenCV framework for face detection at OSCON in Portland, Oregon. In the video above, Mac Slocum interviews Alasdair from the expo floor of OSCON.
For more information on Alasdair’s talk, check out his summary and slides.
Great stuff – looking forward to the book!
The iPhone 4′s forward-facing camera will also allow the successful magic mirror metaphor to be used for augmented reality apps and allow the device to be kept still.

Face-detection is also a good way to gauge a viewer’s attention:
