Q.1. The organization you work for, “White Goods International Ltd. (WGI)”, has decided to use symbols to display information to the user on the functions of its new range of “Master Chef” cookers. For example, the timer function may be indicated by a symbol which looks like a clock. The cooker design team at WGI has developed two sets of symbols that they are convinced are suitable for the new cooker range. You have been tasked with determining which set of symbols is most appropriate from an ergonomics perspective.
Develop a research protocol to determine which set of symbols is most appropriate for the “Master Chef” cooker range. Provide a rationale for each aspect of the protocol.
Q.2. Write short notes on three of the following:
a) Human-machine systems b) Decomposition task analysis c) Short term or working memory d) Visual acuity e) The process of reading f) Emergent features and object displays
Q.3. a) What are the key considerations in the design of a dynamic visual display, e.g. a speedometer?
b) A chemical process requires the addition of a significant amount of heat in order for the required reaction to take place. In order to ensure the reaction is under control, the operator must monitor both the temperature and pressure of the process. The chemical reaction will proceed normally between 25 and 45 degrees C. However, below 25 degrees C it will stop. Above 45 degrees C it will gradually go out of control and will explode if it reaches 99 degrees C. Pressure will vary between 150 and 200 kPa (KiloPascals) under normal operations, however precise readings of pressure to within 5kPa are required in order to optimize the process.
Sketch appropriate designs for displays to be used to monitor pressure and temperature for the above process. Provide justification for each feature in your display.
