Hypertags, small electronic tags using infrared signals, can be discreetly attached to information display surfaces such as billboards or walls, to enable mobile-phone or PDA users to receive small amounts of data by pointing and clicking. Wired News Promoters of the technology envision sending URLs where the user could access digital content such as background nformation on an art exhibit, further information on an advertised product, local sightseeing information, further information on an advertised product, direct access to a film’s webpage, further information on an advertised product, get the drift? If this catches on, I predict that the almost endless interesting, innovative and really useful applications (off the top of my head, how about sites to find further information on health conditions or prescription drugs? hypertags on buses or trains sending you someplace to get updated schedule information? directions from central directories to particular locations in large complexes such as university campuses?) will be swamped by the crass pedestrian ones even much more quickly than they came to be on the Internet. On the other hand, I don’t ever foresee wanting to do much surfing on my cellphone or even my PDA. No matter how gorgeous the color, the form factor is inimical to web-browsing and only slightly more useful with “clipped” content. While it wouldn’t be realtime, about the best use I imagine for hypertags would be to dump the collected URLs from my phone or my PDA onto a desktop system later on, for further investigation on a reasonable display.
