Relationship of blink, affect, and usability of graph reading tasks

Abstract

Dynamic graphs that represent a great deal of time series data have become increasingly common these days. Although previous research revealed that blink facilitates visual search tasks by attracting human attention, blink features have not been clearly evident in a dynamic graph reading context. This study examines the effects of blink on the user’s affective experience and usability of using a blinking line graph. Additionally, this study describes the empirical experiment setup for investigating the characteristics of task types as a moderator to the relationship between blink and the user’s experience. This research aims (1) to theoretically contribute graph comprehension domain by investigating the effects of blink on a graph comprehension process, (2) to design a quantitative experiment and to propose possible hypotheses, and (3) to understand the influence of task types on reading of a blinking graph.
