- What it is
- A text transcription experiment that varied how often a mobile keyboard showed word and correction suggestions: always, never, or only above a probability threshold. It measured keyboard actions, subjective preference and entry time.
- How much weight it carries
- Peer-reviewed CHI paper from Google Research. Participants transcribed given sentences, not composed text, and the experiment used a laboratory setup rather than everyday use.
Facts taken from this source
- In the same study, more assertive suggestions reduced the number of keyboard actions needed to enter text and were subjectively preferred by participants.

- In a 2016 CHI study of mobile keyboard suggestions, the authors found that the costs of attending to and using suggestions impaired average time performance.
