Part II.

3. Research Procedure

The task objective is to facilitate the process of collection understanding

through intuitive and fluid interaction. Collection understanding is a

challenging concept. How can an investigator deduce when an individual

has attained an understanding of a collection? In some sense, subjectivity

plays a major role. Defining what constitutes new knowledge or insight is

a highly personal experience dependent upon individual backgrounds and

prior familiarity with Picasso. To gauge a qualitative experience, the study

will employ a think-aloud protocol, in which an active conversation with

the participant provides us with some sense of what thoughts and creative

relationships are formulated in the participant’s mind.

Participants will be given specific task(s) to complete. Participants will

answer one or more of these questions by writing a descriptive response,

in addition to creating a collection of images to support that response. The

tasks can be any one of the following questions:

1. What do you think is Picasso’s main focus/topic/subject in this

collection?

2. Choose images from the collection that you like and dislike.

Compare/contrast these images and state why you liked/disliked them.

3. Which works of Picasso appealed to you the most? What are the

connections/relationships among them?

Each subject needs to develop some sense or understanding of the

collection in order to complete task(s). A portion of each task will be

directed towards the participant’s subjectivity in interpreting the task and

coming to their own conclusions about the collection.

This test is designed to give the user a qualitative experience interacting

with the images (i.e. the actual contents) in the Picasso collection. How

the user goes about finding out what is in the collection is a qualitative

experience. Quantitative measures of feature use will also be logged to

illustrate whether the task of understanding the collection was tedious.

Approximately 30 participants will be divided equally and randomly. The

first set of 15 participants will use the Collection Understanding interface

(see Figure 1) and the second set (of 15 participants), the “control” group,

will use the IR interface (see Figure 2). Each group will be asked to

provide a representative set of artifacts that exemplify their conclusions.

Using the Collection Understanding tool, users may illustrate the resulting

collage or choose the artifacts in a different window. With the IR interface,

users will right-click on the image, choose the “Save Image As…” menu

option, and place all their images in one folder.
