Move the Camera

How do artists achieve depth in their paintings? They paint objects in the foreground, middle ground, and background. Think of each ground as a separate layer in Flash (Figure 6.30). To achieve parallax scrolling, each layer must move at a different speed.

The smaller screen has a limitation in displaying the information to be provided on a single screen. Therefore, information is provided by scrolling or paging method in which the screen is divided into appropriate pages. Scrolling provides information that goes beyond the size of the screen, one row at a time, allowing the user to navigate continuously and incrementally. When much information is provided, paging and scrolling are useful.11 If the user cannot find the desired menu or information on the provided screen, the user can navigate through the page conversion.29 When information was provided on a small screen, it was more of a screen transition than on a large screen.30 Four types of navigation techniques including scrolling and paging were surveyed.30 As a result, the time tends to be longer when it is provided via scrolling. Menus using scrolling generated more visual fatigue than menus using paging.31 In previous studies, user performance and subjective measurement were highly evaluated when presented as paging rather than by scrolling. However, there were some conflicting conclusions. For example, it showed that menus using paging were less popular than menu using scrolling.29 In the past, scrolling was a factor that hindered usability. However, nowadays, as users have more experience using the internet, they have become accustomed to the scrolling method and are being used variously.32 This means that it is necessary to derive a suitable method for the user of very small screen devices where the use of paging and scrolling is inevitable.
How does Parallax Scrolling Influence User Experience? A Test of TIME (Theory of Interactive Media Effects)
Published in International Journal of Human–Computer Interaction, 2018
Parallax scrolling technique belongs to the concept of motion parallax, which allows individuals to view the object on the front-page moving faster than the object on the back page, thereby creating depth of images to users (Wang & Shyu, 2014). Some have suggested that parallax scrolling has advantages in increasing visitor engagement, holding visitor interest, directing the course of visitor attention, making the site easily navigable, storing all content on one single page, and creating a compelling narrative around the brand promoted by the site (Rutherford, 2014).
