We’ve now discussed seven principles of psychology you can immediately start to account for in your design to increase use and usability. This chapter provides a fictitious case study of a smartphone application in which the design team incorporated all or some components of many of the principles we have covered. The case study asks you to provide insight into what decisions you’d make, and then highlights how the KidTech team incorporated the principles.
