Head-mounted augmented reality (AR) enables embodied in situ drawing in three dimensions (3D). We explore 3D drawing interactions based on uninstrumented, unencumbered (bare) hands that preserve the user's ability to freely navigate and interact with the physical environment. We derive three alternative interaction techniques supporting bare-handed drawing in AR from ...

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 typing performance. Besides reporting distributions and confirming some earlier findings, we report two new findings. First, letter pairs that are typed by different ...

Entering text on non-desktop computing devices is often done via an onscreen virtual keyboard. Input on such keyboards normally consists of a sequence of noisy tap events that specify some amount of text, most commonly a single word. But is single word-at-a-time entry the best choice? This paper compares user ...

This course introduces computational methods in human--computer interaction. Computational interaction methods use computational thinking -- abstraction, automation, and analysis -- to explain and enhance interaction. This course introduces optimization and probabilistic inference as principled methods. Lectures center on hands-on Python programming, interleaving theory and practical examples.
Keywords: computational interaction, inference, machine learning, optimization

Interface designs on both small and large displays can encourage people to alter their physical distance to the display. Mobile devices support this form of interaction naturally, as the user can move the device closer or further away as needed. The current generation of mobile devices can employ computer vision, ...

This course will introduce computational methods in HCI. As interfaces become more sophisticated, designing them requires an exponentially expanding set of design decisions to be made. Hand-tuning can only explore a tiny fraction of the design space. Computational approaches are needed to delegate the minutiae of design and empower HCI ...

The popularity of mobile devices with large screens is making single-handed interaction difficult. We propose and evaluate a novel design point around a tilt-based text entry technique which supports single handed usage. Our technique is based on the gesture keyboard (shape writing). However, instead of drawing gestures with a finger ...

The primary focus of our workshop is on exploring ways to enable inviscid text entry on mobile devices. In inviscid text entry, it is the user's creativity that is the text-creation bottleneck rather than the text entry interface. The inviscid rate is estimated at 67 wpm while current mobile text ...

The majority of software is still written using text-based programming languages. With today's large, high-resolution color displays, developers have devised their own "folk design" methodologies to exploit these advances. As software becomes more and more critical to everyday life, supporting developers in rapidly producing and revising code accurately should be ...

We present VelociTap: a state-of-the-art touchscreen keyboard decoder that supports a sentence-based text entry approach. VelociTap enables users to seamlessly choose from three word-delimiter actions: pushing a space key, swiping to the right, or simply omitting the space key and letting the decoder infer spaces automatically. We demonstrate that VelociTap ...

Dasher is a promising fast assistive gaze communication method. However, previous evaluations of Dasher have been inconclusive. Either the studies have been too short, involved too few participants, suffered from sampling bias, lacked a control condition, used an inappropriate language model, or a combination of the above. To rectify this, ...
