UX Design Foundations

User Experience (UX) Design focuses on ensuring user satisfaction through product functionality, ease of use, and pleasure provided in the interaction with the product.

Usability is key in UX design. A usable interface is intuitive, offers ease of learning, efficiency of use, memorability, error minimization, and user satisfaction.

Donald Norman's emotional design model includes three layers: visceral, behavioral, and reflective. This model explains how users form attachments to products beyond mere functionality.

UX employs human-centered design by focusing on the end user's needs at every stage of the design and development process, ensuring the product solves real problems.

Aesthetics have a profound impact on usability. Attractive products are perceived as more usable, creating a positive emotional response that can forgive minor usability flaws.

Accessibility ensures users with disabilities can effectively use products. Implementing WCAG guidelines can enhance UX for all users, not just those with impairments.

Fitts's Law predicts that the time to acquire a target is a function of the distance to and size of the target. This principle is used to design more efficient, user-friendly interfaces.
