Such technology comes at a time when cell phone manufacturers are actively looking at ways to integrate projectors into their products. And, as with many technologies with social implications, microprojectors have the potential to (once again) change the way people communicate, increasing the sharing of videos and photos, and potentially encouraging more image-based communications in business.
Microvision doesn't expect to have a commercial product available until 2008. And then, microprojectors will have to be economical and energy-efficient enough to be practical for the mass market.
