Exploring Trajectory Attributes in Brest Harbor
We describe a procedure for analyzing trajectory attributes that in-cludes spatial clustering of the trajectories and visual analysis of the distribution of attribute values in the temporal and spatial dimensions
WAYLA - Generating Images from Eye Movements
We present a method for reconstructing images viewed by observers based only
on their eye movements. By exploring the relationships between gaze patterns
and image stimuli, the "What Are You Looking At?" (WAYLA) system learns to
synthesize photo-realistic images that are similar to the original pictures
being viewed. The WAYLA approach is based on the Conditional Generative
Adversarial Network (Conditional GAN) image-to-image translation technique of
Isola et al. We consider two specific applications - the first, of
reconstructing newspaper images from gaze heat maps, and the second, of
detailed reconstruction of images containing only text. The newspaper image
reconstruction process is divided into two image-to-image translation
operations, the first mapping gaze heat maps into image segmentations, and the
second mapping the generated segmentation into a newspaper image. We validate
the performance of our approach using various evaluation metrics, along with
human visual inspection. All results confirm the ability of our network to
perform image generation tasks using eye tracking data

Exploration through drawings in the conceptual stages of product design
This paper argues that sequences of exploratory drawings - constructed by designer's movements and decisions - trace systematic and logical paths from ideas to designs. This argument has three parts. First, sequences of exploratory sketches produced by product designers, against the same task specification, are analyzed in terms of the cognitive categories of reinterpretation, emergence and abstraction. Second, a computational model is outlined for the process of exploration through drawing and third the model is applied to elucidate the logic in the sequences of exploratory sketches examined earlier
