  • A practical exercise, worth 20% of the mark. This will cover the basics of AR/VR development and some of the practical techniques the students will use in their projects. This is individual work. No mobile device or GPU hours are needed.
  • An AR/VR project worth 80% of the marks:
    • Course projects will be designed by the students following the possible project themes proposed by the lecturer and will be checked by the lecturer for appropriateness.
    • The students will form groups of 2-3 to design, implement, report, and present the course project.
    • The final mark will be an implementation mark (40%), a report mark (20%), and a presentation/demo mark (20%). Each team member will be evaluated based on their contribution.
    • Each project will have extensions to be completed only by the ACS students. Each student will write a different part of the report, whose author will be clearly marked. Each student will further summarise her/his contributions to the project in the same report.
