CHI 09- Steerable Focus











National Taiwan University

Summary
The paper was focused on a mixed resolution table projection display. The display was capable of displaying a large area in low resolution and a small area in high resolution. They built an application which uses Google Maps to display a large map in low res with a small focus area in high res. They tested two methods of moving the focus section. One was with the focus section being fixed in one location and the map would move under it. And the other the map would remain still and the user could direct the focus section, steerable. They tested each method on two tasks and found that users were able to complete the tasks faster with the steerable focus.

Thoughts
The results of the study showed what I thought. In my experiences playing computer games or using software I knew that the steerable focus would be superior. This seems to fit inline with things Don Norman was talking about, mental models, and analogous actions. Being able to steer the focus section is much like using a magnifying glass. The study proves that the action being a reality based interaction is better than the one that is not.
