back to top  1. TypeCase

TypeCase is a keyboard that has just five buttons rather than 50. Instead of typing each key individually, you press chords, just like on a guitar. Built right into a phone case, it allows you to type without looking, with only one hand—even in your pocket. Designed with amputees and hemiplegics in mind, it simplifies a traditional keyboard down to a beautifully intuitive and effortless interaction.

Furthermore, it helps people with visual impairments to type and read: TypeCase uses haptics in the buttons like a digital braille, offering the visually impaired a discrete alternative to the more stigmatizing voice-to-text methods.

Named after the Irish bard Turlough O'Carolan, the Carolan Guitar is a roving collector and teller of stories. Scanning its decorative inlay (Artcodes) or playing fragments of music (Muzicodes) conjures up stories from its digital footprint of how it was made, where it has been, and who has played it. From a research perspective, Carolan is an "accountable artifact," a physical object that can be easily connected to multiple layers of digital content so that it can tell different stories to different people in different contexts. From an impact perspective, it is a hybrid product that blends goods, services, and experiences to enhance provenance, utility, and personal meaning.

Devised by artist Brendan Walker, VR Playground is an interactive artwork that has toured globally, reaching over 15,000 participants to date. Riders get to experience four different virtual worlds that are overlaid on a playground swing. The physical sensation of swinging is visually amplified and distorted to deliver various thrilling sensations. From a research perspective, VR Playground provides an example of a visual-kinaesthetic experience. From an impact point of view, it shows how to overlay swing rides—and maybe other forms of movement—with virtual experiences.

back to top  4. Brian

Even though it is no secret that physical training enhances one's health, many still lack intrinsic motivation to work out consistently. Drawing on this issue, we designed an interactive barbell disk: BRIAN. Based on the famous memory game Simon Says, BRIAN gamifies barbell training by demanding both the user's physical strength and cognitive skills. The disk is connected to an app that shows a random order of colors. Each color is linked to a barbell exercise. The players should execute these exercises in the order in which they are presented on the app. If the exercise is done right, players proceed to the next level.
