IB Design Technology Topic C1.3: Beyond Usability Key Definitions

Attract refers to how a product catches the user’s attention and creates a strong first impression.

The ACT Model is a framework used to design products that intentionally trigger emotional responses and improve how users relate to and experience a product. It includes three stages: Attract – aesthetics, Converse – interaction, and Transact – function.

How the user interacts with the product and receives feedback.

A model that encourages designers to create for pleasure and emotional impact. It identifies four types of pleasure: socio-pleasure, physio-pleasure, psycho-pleasure, ideo-pleasure.

Pleasure from personal values, beliefs, or aesthetics. This occurs when a product reflects what the user cares about, such as sustainability, ethical choices, minimalism, or cultural identity.

Pleasure from mental satisfaction, ease of use, or a sense of control. This happens when a product is intuitive, efficient, or gives clear feedback. It can also come from solving problems or completing tasks.

Pleasure from social connection or identity. Coming from how a product helps users interact, belong, or express status.

How the product performs its function and delivers value.
