- What it is
- A University of Toronto student report on a head-mounted display that shows real-time captions, with two small studies of how much caption delay viewers accept.
- How much weight it carries
- Not peer-reviewed and small: the latency study had 5 participants. It is useful for the delay question, not as a general measurement of smart glasses.
Facts taken from this source
- A University of Toronto report on AR captioning says the lag for captions should never exceed 5 seconds, and that 80 percent of captions should appear within 3 seconds.
“the lag time for captions should never exceed 5 seconds, and 80% of the captions should never exceed 3 seconds” (Introduction and Study 1)
