02 What is Interaction Technology: Understanding Interaction

In our daily life, the daily use of mobile phones is equipped with interactive systems, and bank self-service machines allow users to interact with each other to withdraw money and so on. In fact, in a broad sense, the definition of interactive technology is: technology that helps people complete tasks and achieve goals. In the context of the Internet, it may be defined as, based on computer systems, combined with coding to help people complete tasks, achieve goals, and entertain themselves.

There are user interfaces for any complex system, such as notebooks, coffee machines, printers, etc. that are used on a daily basis. The most important thing is how to guide the user to complete the task on the interface and operation, and understand his current task execution status.

The point is that interactive systems are usable, and designers and products should make them usable.

1. Human Behavior Path

The normal path of human behavior is to acquire cognition -> self-interpretation -> evaluation -> goal -> intention -> clear action -> execution -> task completion. But user behavioral paths can easily lead to misunderstandings when evaluating how to accomplish goals. That is, the page cannot give correct usage feedback or the user cannot understand the design of the interface, resulting in the failure to complete the goal. This requires designers to give it usability in the product design.

2. Usability

Usability is one of the broad terms of "user experience" and refers to the ease with which a product/website is accessed or used. The official ISO 9241-11 definition is: "The degree of effectiveness, efficiency and satisfaction with which a product is used by a specified user in a specified use environment to achieve specified objectives."
