Aims & Learning Objectives: Aims: To enable students to understand and be able to apply current approaches to modelling and design of communication systems. To approach the design of communication systems from a human and task perspective and to consider the most suitable application and optimal design of the technologies to support effective human communication. Objectives: The students should be able to apply scientific and engineering principle s to the effective and creative design of communications systems. They should be able to critically assess communication systems and to identify how technologies may be applied to support more effective communication. Content: Introduction to participatory design. Understanding of how to model and specify group and communication requirements. Conceptual design models and metaphors. How to elaborate a design model. The unit will involve practical classes through groupwork in the design of communication systems; building exemplars, interface design, communication management design, security access design.

CM50170: Dissertation 
Credits: 30 
Level: Masters 
Dissertation period 
Assessment: DS100 
Requisites: 
Before taking this unit you must take CM50175. Before taking this unit, students must obtain the required standard in the MSc in Computer Science taught units. 
Aims: To develop skills of individual
project effort in a computer based practical undertaking with original development
content related to one or more of the lecture modules studied. Learning Outcomes: A student will be able to; * identify the tasks to be completed in a project proposal, plan a scheme of work, and complete the project to a professional standard; * assemble and create the necessary software tools, carry out the development of the solution of a technical problem in computer science, and evaluate the effectiveness of the solution against common standards of quality; * demonstrate the successful completion of these tasks in a wellstructured and coherently written dissertation. Content: The student will follow an appropriate problem solving route, building on the project proposal written in CM50175 Research Project Preparation. The student will analyse possible problem solutions and choose appropriate methods and approaches. This will lead to the implementation of the chosen solution, its testing and evaluation. Projects are usually softwarebased, but suitable experimental or theoretical projects may be undertaken. A comprehensive dissertation will be submitted at the completion of the project. 
CM50175: Research project preparation 
Credits: 6 
Level: Masters 
Semester: 2 
Assessment: PR10CW90 
Requisites:
