Week 5: Low Fidelity Prototype

In this weeks lecture and tutorial, we talked about Prototype & Evaluation, which will better assist us with our Project.

Ragu discussed the process of paper prototype development & evaluation and the steps that are required in this process, which are:

1. Development Process: Groundwork when developing a prototype, and list all the goals that you want to achieve from your proposed solution. Wireframes & scenarios are a good idea to achieve this.
2. Evaluation Process: Testing and evaluating your prototype to help determine any factors that need to be improved or changed.

Ragu also explained that there are 5 principals of usability:

1. Effectiveness
2. Efficiency
3. Satisfaction
4. Learnability
5. Memorability 

This process if vital for my Project.

Some points to take into consideration when evaluating our prototype, these include Inspection Methods which is not required to include users, and is usually conducted by individuals with an expertise in Usability. Some Inspection Methods include:

• Cognitive walk-thorugh
• which is the method a number of evaluators ask a series of questions from the point of view of the user. Its main purpose is to understand the 'system's learnability for new users' (Ragu).
• Heuristic evaluation
• evaluation that is mainly carried out by experts (Ragu).
