Now a days, the word cognitive is buzzing in every aspect and more likely in AI and ML. Today, let me share how Cognitive Model can be used for creating better user experience. A cognitive model is a model that behaves like a human being by copying the cognitive processes people go through to complete a task. It is derived from cognitive science, which is “The mental action or process of acquiring knowledge and understanding through thought, experience, and the senses”. Cognitive modeling can help HCI in the design and evaluation of alternatives interface. A cognitive model can replace a human user to predict how users will perform on a system before it is implemented or even prototyped.
A system can generate a cognitive model of an end user currently interacting with the design and modify the interaction of the user with respect to the design to understand different outcomes. Finally, cognitive models in design can replace a groups of individual users and can act in those situations that require many participants. Consider your designing a banking application which include multiple personas and multiple users using it, in such hugh applications asking multiple questions to multiple users to derive the best possible user flow and understanding how will the user react to the flow is crucial. This reasearch itself is a tedious time consuming task. Having a Cognitive modal do all this not only saves per and post research time but also can help giving the user a better user experience from the day one.
Cognitive models in design can substitute directly for people so groups of individuals can be simulated in situations that require many participants
Cognitive models are used in psychological research in several ways. They serve as a means to understand human behavior. In general, it is nothing but building a tool or a model which can help in understanding human behaviour under certain assumptions, with each assumptions we will be able to understand how the modal behaves and by changing those assumptions in the model we can see how the design behaves differently.
So, cognitive models are useful tools for psychologists, but why should interaction designers care about cognitive models? Cognitive models for human-computer interaction (HCI), have a completely different goal altogether. In general, they are used to make interfaces “better” for users. There are at least three different uses for cognitive models in service of this general goal.
- Predicting human behavior on proposed(assumed) interactive systems
- Changing the user as a guide for adaptive interaction and observe the outcomes
- Replacing models in place of other participants in group interactions
