Interaction design is an academic subject that focuses on both the form and function of digital products. Individuals who work in this field may help design interactive technologies, computer programs, and websites for companies or for their own businesses.

Requirements for the PhD program often involve the student having already obtained a Master’s degree. Additionally, a thesis or dissertation primarily consisting of original academic research must be submitted. In some countries, this work may even need to be defended in front of a panel.

Part time learning allows one to obtain part-time degrees even if one cannot attend school on a full-time basis. One can learn at his or own pace, gradually accumulating credits which count towards final qualification.
