The attract/converse/transact (ACT) model is a design framework used to improve the relationship between a user and a product. It helps designers intentionally trigger positive emotional responses by considering the product’s desirability, usability, and usefulness.
How the ACT model works
The model examines three complementary aspects of the user experience:
| ACT component | Design focus | Intended effect |
|---|---|---|
| Attract | The product’s aesthetics, including its appearance, sound, texture, colour, and form | Captures attention, creates a positive first impression, and makes the product desirable |
| Converse | The interaction between the product and user, including controls, feedback, prompts, and responses | Makes the product understandable and easy to use, supporting usability |
| Transact | The product’s function and its ability to help the user complete an intended goal | Delivers practical value and demonstrates usefulness |
For example, consider a smart alarm clock. Its elegant form and calming display attract the user. Clear controls, responsive buttons, and understandable visual or audio feedback allow it to converse with the user. Reliably setting alarms and waking the user at the required time completes the transaction.
Together, these elements move design beyond basic functionality. A product may perform its technical function but still create a poor user experience if it is unattractive or difficult to operate. Conversely, an attractive product will not maintain a positive user relationship if it cannot perform its intended function.
A common misconception is that ACT describes three strictly chronological stages. Instead, it provides three connected design considerations that should be addressed throughout product development.
IB exam technique
This model appears in C1.3 Beyond usability (HL only). For a command term such as suggest, apply each ACT component to the named product and explain how a specific design feature could trigger a positive emotional response. Do not merely define the three terms: connect attract to desirability, converse to usability, and transact to usefulness.
