Watching this Chris Dixon interview this morning helped me appreciate that Google Glass has real-world non-trivial applications.
1. A teacher giving a lecture while drawing a diagram on whiteboard.
2. As a teleprompter for a person giving a speech.
3. A doctor reviewing test results while examining a patient.
4. An architect looking at designs on a site visit.
5. Watching your heart rate while riding a bike.
6. Sign-language interpreter for a real-time meeting.
7. In general, as a heads-up display for jobs that require use of your hands and access to information, at the same time.
Honestly, I had not thought of these applications until Dixon explained.
And of course there are trivial applications, like watching Green Acres while pretending to pay attention to someone talking. ;-)
