Occasionally what does happen is that people, knowing they’re near death, will have a video of themselves speaking to their unseen audience about their own lives, their hopes for their families’ futures, their love for so and so. This, too, is a bit eerie. But it can be wonderful to see someone we’ve lost seemly come to life again.

There are simple things available to us now or conceivably available that serve a better purpose. We can look at photos, watch videos, read old letters (and e-mails and diary entries), read the Valentines Day and birthday cards we’ve received and continue talking about this person with friends and family. Maybe not as fascinating as the Envoy app, but continually comforting.

Subtitles on the cinema screen, for all to see. Although this is the preferred way to view cinema subtitles amongst most people that need them to enjoy a film, it requires cinemas to put on separate shows. Most people can’t work their lives around one or two cinema shows a week, so currently, most people that would like to attend subtitled cinema shows can’t do so. There’s not enough choice of films and showtimes.

A ‘personal’ subtitle system, like the specs mentioned, or seat mounted displays, like they have in the US, would give people a better choice of films and showtimes, which would of course result in more people attending the cinema, purchasing popcorn & drinks etc.
