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)
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)
Inspired by the contrast between 'classical' and 'expressive' visual aesthetic design, this paper explores the 'visual complexity' of images. We wished to investigate whether the visual complexity of an image could be quantified so that it matched participants' view of complexity. An empirical study was conducted to collect data on the human view of the(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 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)
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)
Play is important in the early development of young children, as it encourages them to explore the world, develop skills and learn to socialise with their peers. Blind and visually impaired children face challenges that can stop them becoming involved in play activities at nursery and school, leading to dependence on adults and reducing the benefit of(More)
In this paper we describe a demonstration of our multimodal affective feedback designs, used in research to expand the emotional expressivity of interfaces. The feedback leverages inherent associations and reactions to thermal, vibrotactile, auditory and abstract visual designs to convey a range of affective states without any need for learning feedback(More)
