### Results of the Preliminary Study  
This sub-section presents the findings in achieving the first goal of the preliminary study. The analysis discussed in this sub-section is based on 2 post-questions asked of the participants during the preliminary study. The questions were:  
1. Based on the two information visualization approaches that have been introduced (Structured type and Scattered type), which approach do you think could help your interaction on a large display? 2. Based on two information visualization approaches, which approach do you think is suitable to be applied to museum application? The data presented in Figure 4 was based on the first (i) post-question being asked during the preliminary study. The significance of determining the concept is that a different domain of application may hire a different way of presenting the information, especially on a large display. Having a specific structure for organizing the information, may help users to focus and complete a task more efficiently. From Figure 4, a pattern of user interaction on a large display for the museum environment can be seen. With five participants, the number of persons who chose a scattered format to provide information is higher than the one who chose a tree concept. In the meantime, four more participants decided between a scattered or structured information visualization. This demonstrates that during their study of the sessions, users favoured the scattered type for the museum application. This may be the case since the scattered type is the default information visualization for the museum application interfaces being researched. This choice may indicate that the participants enjoyed engaging with the museum interfaces throughout the investigation. Four participants favoured either a scattered or structured type of information visualization for the environment, demonstrating the value of both types of presentation. To put it another way, both forms of information visualization should be considered during the design process. A secondary evaluation was conducted to substantiate the participants' decisions, which were based on the second (ii) post-question of the preliminary survey. This aimed to see if there is a link between the preferences of participants for information visualization and their collaborative engagements with the museum environment. The observed outcomes are represented in Table 5.  
Participants 2, 4, 8, 9 and 10 as shown in Table 5 chose a scattered type of information visualization since the concept is fascinating and enjoyable to them. There are various elements of the study that need participants to comprehend the museum's chronological history. The images in this section are dispersed; however, they are labelled with numbers to help participants follow the story. When the participants arrived at the segment, they spontaneously structured the tale in the manner they desired. This demonstrates that the concept can connect several individuals to interact with the interface since they can assist one another in plotting the story (Participant 8). For Participant 2, arranging the images was exciting because scattered information is like a puzzle, and it serves as motivation to find and finish the task. Participants 9 and 10 said that the scattered type is intriguing and that learning through pictures is simple. Participant 1 stated that a scattered type has a good presentation because all the information is displayed on a single screen. When a section is accessed, for example, all of the graphics in that area are grouped in the centre.
