|moblogs are just a glimpse into what is coming with always-on wearable cameras|
Mobile phones and PDAs with cameras are increasingly common; one in six phones sold in 2003 had a camera in it, and last year camera phones actually out-sold other digital cameras. The bigger change will come from an entirely-new class of hardware — what I call the “personal memory assistant.” Both Hewlett-Packard and Microsoft have built test versions of wearable cameras designed to record the world around you as you go about your day. If you’ve seen or used a TiVo, imagine a TiVo for your day-to-day life. If you don’t think that’s revolutionary, consider that human memory is notoriously faulty; what happens when a person can have perfect recall?
