Motion to support rapid interactive queries on node--link diagrams
Colin Ware, Robert Bobrow
Pages: 3-18
DOI: 10.1145/1008722.1008724
Many different problems can be represented as graphs displayed in the form of node--link diagrams. However, when a graph is large it becomes visually uninterpretable because of the tangle of links. We describe a set of techniques that use motion in...

EvoFIT: A holistic, evolutionary facial imaging technique for creating composites
Charlie D. Frowd, Peter J. B. Hancock, Derek Carson
Pages: 19-39
DOI: 10.1145/1008722.1008725
EvoFIT, a computerized facial composite system is being developed as an alternative to current systems. EvoFIT faces are initially presented to a witness with random characteristics, but through a process of selection and breeding, a composite is...

Gazing and frowning as a new human--computer interaction technique
Veikko Surakka, Marko Illi, Poika Isokoski
Pages: 40-56
DOI: 10.1145/1008722.1008726
The present aim was to study a new technique for human--computer interaction. It combined the use of two modalities, voluntary gaze direction and voluntary facial muscle activation for object pointing and selection. Fourteen subjects performed a...

A multimodal learning interface for grounding spoken language in sensory perceptions
Chen Yu, Dana H. Ballard
Pages: 57-80
DOI: 10.1145/1008722.1008727
We present a multimodal interface that learns words from natural interactions with users. In light of studies of human language development, the learning system is trained in an unsupervised mode in which users perform everyday tasks while providing...
