- What it is
- An experiment in which people wrote image captions with different kinds of predictive text suggestions. The authors compared caption length, vocabulary and typing speed across suggestion conditions.
- How much weight it carries
- Peer-reviewed IUI paper from Harvard. The task was short captions, not long documents, so the findings describe short texts.
Facts taken from this source
- The IUI 2020 authors found that suggestions boosted text entry speed, but with diminishing benefit for faster typists.
“Suggestions also boosted text entry speed, but with diminishing benefit for faster typists.” (Abstract)
- In the IUI 2020 study, image captions written with predictive text suggestions were shorter than captions written without them.
“captions written with suggestions were shorter” (Abstract)
