Prerequisites
Main principles and basis of Mechanical Drawing, both handmade and computer-aided, design of machines and manufacturing cycles.

Learning outcomes
KNOWLEDGE AND UNDERSTANDING:
The course allows the students to acquire the necessary technical knowledge required for an integrated use of geometric modelling, simulation and analysis tools, to support production/manufacturing processes. These knowledge will allow the student to acquire the skill required for the use of CAD and virtual prototyping systems aimed to reduce product/process development time
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
For the purpose of addressing the design and productive issues through the implementation of the acquired skills, the student will have to be able to profitably use the geometric modelling and simulation tools to support the design/production processes. This ability will be acquired through a series of professional skills such as: the skill to define tridimensional virtual prototypes; the skill to use virtual prototypes for analysis, validation and design assessment
TRANSVERSAL SKILLS:
The execution of a design exercise, which will be performed by groups of students and that will lead to the development of one or more virtual prototypes, will contribute to improve the student skill of express and support his/her ideas in a technical context, to present results of his/her work in a simple and understandable form

Program
The course is arranged in 42 hours of frontal lectures and 30 hours of exercises at the Virtual Prototyping Lab. It aims at providing methods and tools for the creation of virtual prototypes and their use in design and product validation as well as multimodal and multi-sensorial interaction technologies with particular attention to usability and ergonomics. The course program is based on the following topics: user-centered design methods and systematic approach to product design, advanced systems supporting design and representation, virtual prototyping environments and architectures, solid and surface modeling, principles of geometric modeling, virtual humans and tracking techniques, principles of human-computer interaction, new interaction paradigms based on multimodal, multi-sensorial, desktop or immersive technologies, applications and technologies of Virtual Reality and Augmented Reality, Reverse Engineering techniques. Numerous case studies from industry will be used. The exercises at lab will be organized into 24 hours of CAD for virtual prototyping and 6 hours for the products with high technological, functional, aesthetic and ergonomics values.

Development of the examination
LEARNING EVALUATION METHODS
The evaluation is based on three intermediate esaminations and a final assessment of the drawings and models the students realize during the course to represent their project and an oral exam at the end where questions are submitted to verify the learned lessons.

LEARNING EVALUATION CRITERIA
The criteria for the evaluation of intermediate and final results about the developed projects are: skill on using CAD tools for the representation of solids and surfaces, ability to apply both systematic design approaches and user-centred design methods in product development, competences in adopting virtual prototyping techniques to analyze physical ergonomics. Criteria for the evaluation of the final project are: knowledge of information gathering techniques to create a complete list of user needs and product requirements, ability to think about social and ethical effects of product design to include people with disabilities and/or frailties, competence of problem-solving and identify feasible and innovative design solutions, ability to use proper tools to represent design ideas and analyze the achieved outcomes and finally, ability for team working. The criteria to assess the oral exam are: knowedge of the course topics, skill of analysis and synthesis, ability to apply the achieved competences in specific domains, ability to clearly communicate ideas, concepts and to correlate them.

LEARNING MEASUREMENT CRITERIA
The measurement of the student learning is carried out by the assignment of a score to a set of evaluation metrics that differ according to the type of evaluation (i.e. intermediate tests, final project, oral exam) in order to reach the maximum score of 30/30 and laude. Metrics for the evaluation of the project are: degree of the proposed design innovation, level of project detail and achieved quality, correctness of drawings, models, analysis reports, number of functions that are implemented in the product, degree of product ergonomics and usability. Metrics for the evaluation of the oral exam regard the quality of the presentation and the competences matured on the course topics.

FINAL MARK ALLOCATION CRITERIA
The maximum score is 30/30 and laude. It is achieved by students that demonstrate autonomy in problem-solving and transdisciplinary knowledge of main tools and methods for virtual prototyping in the different examinations (graphic and oral). The minimum scorre is 18/30 and is assigned to students that have an enough knowledge of Virtual Prototyping tools and methods and design a simple product.
