time, interactive animations prove to be pretty useful in keeping the users engaged. They can be leveraged for usability by giving clues about what is currently happening with the system thereby inducing patience in the user. Makes the interaction more fun! Elements such as morphing from one form to another, fading through change of colour, or interactive motions are thought to delight the users and seem to make the design “pop.” Animations, along with sound effects, are commonly found on sites that are built for children. Such elements often tend to distract children; however, because young audiences are generally less goal-oriented than adults, these effects annoy them less and are better tolerated and perceived. Helps overcome Change Blindness Change blindness is the tendency of people to ignore alterations in images, especially when they are placed in a region far away from their focus of attention. The two factors that play a significant role in the likelihood of change blindness are: 1. Disturbance in our visual perception- this can occur when a page reloads. Our eyes quickly seem to jump from one fixation point to another, or when a screen display shifts as a device reorients from vertical to the horizontal presentation. It might lead us to miss out on some details. 2. Speed: Instant changes in visual appearance are more likely to be masked by even brief interruptions. These factors have commonly occurred in digital experiences, where visual elements regularly appear and disappear almost instantaneously. Other factors like attention to detail and overall visual clutter also play a role in change blindness. Generally, any time a new visual element is introduced to an existing display, it is at risk of being overlooked. For example, on the website Vans.com, The Out of Stock message did not seem to grab attention because it looked very similar to the Add to Cart tab, and was placed too far from the user’s field of attention (on the Size and Quantity fields). This slight difference in the icon doesn’t stand out when the rest of the display stays the same (Fig 1.0). Fig 1.0.

For example, using appropriate animation speed and strategic element placement. Fast animations are more likely to distract users when they happen outside the user’s field of view. They are suitable for essential elements that users must attend to and act upon. Strategically place important new visual elements close to the point where the users’ eyes are already focused. Pro tip: Always! Always consider the rule of thirds. (Fig 2.0 Fig 2.0- Rule of thirds simply states that if a wide canvas is divided in three equal parts both vertically and horizontally, the resulting grid helps decide where to place important design elements 23
