Software should convey a sense of calm
Everyone has to understand a software product and learn how to use it. The more complex the product, the more there is to learn. Usually, I have to learn not just one but several things. Where should I start? What follows after that? I will either not read instructions or forget parts of them, and learn by interacting with your product. We always learn or understand things in time and not all at once. We learn faster and are more resilient to frustration when something is fun or enjoyable. If a product is attractive to a particular audience, it further increases identification and willingness to learn.
