Objectives

Augmented reality is a technology which improves and augments the user’s vision of the real world with virtual images, using Computer Vision and Graphical Computing/ Virtual Reality techniques. The main aim of this course is to transmit to the students the basic knowledge of these techniques, allowing them to proceed more advanced studies in the emergent area of Augmented Reality. Furthermore, another aim is to provide the students with the capacity to do little assignments illustrating the methodologies studied. 

Learning outcomes and competences

At the end, the students must be able to:
- identify and characterize the components, structure and functions of a minimum system of augmented and/or virtual reality;
- describe the main algorithms used to implement each component;
- describe the interaction of several components;
- do the integration between real world and virtual object images;
- develop Augmented Reality Applications, by the use of an open source tool (AR Toolkit).

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Computer graphics and OpenGL.

Eligibility for exams

Not exceed the absence limit allowed and have a minimum of 40% in the evaluation assignments.

Calculation formula of final grade

CF = 40*CT + 60%*CE

CF: Final Classification
CT: Practical Assignment classification (average grade of 2 works)
CE: Exam Classification

The two practical assignments are evaluated in class at the end of the time estimated for their elaboration.

To pass, the student must have a minimum of 40% in each of the two evaluation components, distributed and final exam.

Examinations

Special exams (end of graduation and others) are composed by a practical work and a written exam.

Special assessment (TE, DA, ...)

The distributed evaluation is for all the students, regardless of their enrollment regime. The students who cannot attend classes, must agree with professors dates for the presentation of the assignments evolution (subject to evaluation) during the period given for their elaboration, as well as do their presentation on the dates foreseen.

Classification improvement

The classification improvement of the distributed component can be done at the same time as the practical assignments in the following academic year.

Observations

Pre-requirements: basic knowledge of 3D Graphic Computing.
