HCI Lecture 2 : Gestalt Laws


Gestalt laws of perception provide guidelines for how humans naturally organize and interpret visual information. When applied incorrectly in design, it can lead to confusion and frustration. Here are two examples of how these principles can go wrong in digital applications and suggestions for correction:

  1. Unintuitive Website Navigation

Problem :

In some poorly designed websites or apps, the proximity principle, which states that objects placed close together are perceived as related, can lead to confusion. For instance, having unrelated navigation links or buttons too close together can make users mistakenly click on the wrong option

Correction :

Increase Spacing : Increase the spacing between unrelated elements to clearly distinguish them.

Group Relevant Items : Group related navigation items together and use visual cues like dividers or background colors to make the grouping evident.

  1. Ambiguous Button Design

Problem : The similarity principle, which suggests that items with similar visual attributes (e.g., color, shape) are perceived as related, can be problematic if used improperly. For instance, if all interactive buttons on a website look the same, users may struggle to differentiate between primary actions, secondary actions, and non-interactive elements.

Correction :

Use Visual Hierarchy : Apply different visual styles (e.g., size, color, or shading) to distinguish primary actions from secondary or tertiary actions.

Feedback : Provide clear hover effects, transitions, or feedback when users interact with buttons to confirm their action.

It’s essential for designers to understand the Gestalt principles but also to recognize when they need to be intentionally deviated from for the sake of user clarity and ease of interaction. Proper use of these principles can enhance user experience, but misuse can lead to confusion and usability issues.
