The inviscid text entry rate and its application as a grand goal for mobile text entry
Abstract
We introduce the concept of the inviscid text entry rate: the point when the user's creativity is the bottleneck rather than the text entry method. We then apply the inviscid text entry rate to define a grand goal for mobile text entry. Via a proxy measure we estimate the population mean of the sufficiently inviscid entry rate to be 67 wpm. We then compare existing mobile text entry methods against this estimate and find that the vast majority of text entry methods in the literature are substantially slower. This analysis suggests the mobile text entry field needs to focus on methods that can viably approach the inviscid entry rate.

The transcription-centric model of writer-suggestion interaction assumes writers have a concrete, translated proposal ready when they encounter a suggestion, and the system only helps transcribe it.
“This 'transcription-centric' model of writersuggestion interaction, as implied by past studies, assumes that writers have a concrete, translated proposal ready in mind when they encounter a suggestion, and the suggestion system merely helps them transcribe it.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
