Describe the purpose of the device • Describe the tasks and how they are carried out.

following is a list of Consumer products (electronics & appliances) 1. Microwave 2. Washing Machine 3. Dish washer 4. Standalone Digital Camera (Not the Phone Camera) 5. Camcorders 6. Mixers 7. Game Console (e.g., PS, Xbox, Wii) 8. AC Unit in house or car 9. Portable music player/ iPod 10. Home Stereo or home theatre system 11. Car navigation system/GPS or handheld GPS 12. Car stereo system 13. Non smart phone 14. Photocopier/Printer 15. Telephone answering machine 16. Scientific Calculators (e.g. TI-84) Note:You can choose another product- discuss with your teacher first. You cannot evaluate a website, an app nor a software. 1. Choose a product from the above list. Each student should have a different product. Product: _______________________________ Make:__________ 2. Take clear 4photographs of the interface. The photograph should provide some explanation related to the usability and/or design criteria. Additionally, they should be clearly labeled and numbered. 3. Describe the interface using clear English(100-200 words): • Write the appliance’s name, make and model. • Describe the purpose of the device • Describe the tasks and how they are carried out. 4. Write a well formatted report a. cover page: Case Study for consumer product’s name, student’s name & id, course number and name, section, teacher’s name, date and a picture b. table of contents c. introduction d. page numbering e. start every section on a new page. 5. Conduct a Hierarchical Task Analysis and draw theHTA diagram (roughly 5 diagrams horizontally and 4 levels deep) and include it in your report. Clearly number and label each task and specifypreconditions, plans, options and repetitions. Use Word’s smart arthierarchy for this task. 6. Evaluate the Interface using the criteria presented in class. These are the following • Usability – effectiveness, efficiency, safe to use, memorability, learnability • Design criteria – visibility, feedback, constraints, consistency, affordances 7. How would you modify the interface to improve the design? List at least 3 suggestions in your report with reasons why. 8. Conclusion.
