Above-device gesture interfaces let people interact in the space above mobile devices using hand and finger movements. For example, users could gesture over a mobile phone or wearable without having to use the touchscreen. We look at how above-device interfaces can also give feedback in the space over the device. Recent haptic and wearable technologies give(More)
The influence of ocean circulation changes on atmospheric CO2 hinges primarily on the ability to alter the ocean interior's respired nutrient inventory. Here we investigate the Atlantic overturning circulation at the Last Glacial Maximum and its impact on respired carbon storage using radiocarbon and stable carbon isotope data from the Brazil and Iberian(More)
When users want to interact with an in-air gesture system, they must first address it. This involves finding where to gesture so that their actions can be sensed, and how to direct their input towards that system so that they do not also affect others or cause unwanted effects. This is an important problem which lacks a practical solution. We present an(More)
Gestures above a mobile phone would let users interact with their devices quickly and easily from a distance. While both researchers and smartphone manufacturers develop new gesture sensing technologies, little is known about how best to design these gestures and interaction techniques. Our research looks at creating usable and socially acceptable(More)
When introducing interactive tabletops into the home and office, lack of space will often mean that these devices play two roles: interactive display and a place for putting things. Clutter on the table surface may occlude information on the display, preventing the user from noticing it or interacting with it. We present a technique for dealing with clutter(More)
Designing interactive systems for older adults often means designing with older adults from the earliest stages of development. This paper describes the co-design of a smartpen and paper calendar-based reminder system for the home. The design sessions involved older adults and used experience prototypes [1]. We completed these co-design sessions with older(More)
In-air hand gestures allow users to interact with mobile phones without reaching out and touching them. Users need helpful and meaningful feedback while they gesture, although mobile phones have limited feedback capabilities because of their small screen sizes. Interactive light feedback illuminates the surface surrounding a mobile phone, giving users(More)
For visually impaired children, activities like finding everyday items, locating favourite toys and moving around the home can be challenging. Assisting them during these activities is important because it promotes independence and encourages them to use and develop their remaining visual function. We describe our work towards a system that adapts the(More)
Recent technologies allow us to interact with our homes in novel ways, such as using in-air gestures for control. However, gestures require good feedback and small appliances, like lighting controls and thermostats, have limited, or no, display capabilities. Our research explores how other output types can be used to give users feedback about their(More)
