Reading #3

1. When defining the term “pre-attentive”, he mentions the term “active viewing”, implying that there are at least two different kinds of ways to view/look at something. What is the difference between active and passive (assumed other way of viewing)?

2. When is it more important for the viewer to be able to learn a pattern, ex. page 43 versus to be able to understand the chart immediately or at first glance?

3. On technology and its effects on visualization, does this possibly mean that only those who have grown up around these kinds of visuals generated by newer technology will understand? For example, are the images from pg 49 intuitive for most people?
