Welcome to the course Development for Mobile, Wearable and Smart Devices! This course continues the subject of user experience design by first focusing on high-fidelity prototypes and wire-frames for mobile and wearable devices. After introducing the technology of connected devices, the focus shifts to the design for smart devices, and cross-device interactions. The development part starts with the recapitulation of object-oriented programming in JavaScript. Cross-platform development of mobile applications is introduced next with the help of the mobile application framework Vue Native. It includes building a mobile application being able to manage user accounts, store data, and use different services provided by the mobile device platform.
