An interesting idea but I wonder about implementation practicability? Having used "light beam communicators/controllers" (aka TV remote controls and LED based line of sight setups) I wonder how the system will deal with the normal loss of signal say when someone walks in front of you. Also, using it outside would be great on those clear nice days, but snow, rain, sleet, fog, etc would render this non-operational (well maybe not for IR..). It seems like a fun idea but I question whether it can really make a visible impact on personal devices/car communications. A good read though, it brought back memories, thanks!

Quite an interesting article! I never thought about this. Though it appears the applications are a little limited since they have to respect the interaction between the human eyes and environment and the data being transmitted. Nevertheless it sounds like a real smart turn to illumination since we would be using one device for two purposes.

Wow! What a good idea. At least, that's what I thought when I read about it 25 years ago.
