The term'participation'is traditionally used in HCI to describe the involvement of users and
stakeholders in design processes, with a pretext of distributing control to participants to …

We report on typing behaviour and performance of 168,000 volunteers in an online study.
The large dataset allows detailed statistical analyses of keystroking patterns, linking them to …

This paper presents a large-scale dataset on mobile text entry collected via a web-based
transcription task performed by 37,370 volunteers. The average typing speed was 36.2 WPM …

Emoji, a set of pictographic Unicode characters, have seen strong uptake over the last
couple of years. All common mobile platforms and many desktop systems now support emoji …

The advent of wearables (eg, smartwatches, smartglasses, and digital jewelry) anticipates
the need for text entry methods on very small devices. We conduct fundamental research on …

Touchscreens have become a de facto standard of input for mobile devices as they most
optimally use the limited input and output space that is imposed by their form factor. In recent …

Mobile keyboards often present error corrections and word completions (suggestions) as
candidates for anticipated user input. However, these suggestions are not cognitively free …

To improve the accuracy of target selection for finger touch, we conceptualize finger touch
input as an uncertain process, and derive a statistical target selection criterion, Bayesian …

A virtual keyboard takes a large portion of precious screen real estate. We have investigated
whether an invisible keyboard is a feasible design option, how to support it, and how well it …

Users often struggle to enter text accurately on touchscreen keyboards. To address this, we
present a flexible decoder for touchscreen text entry that combines probabilistic touch …
