Human-Computer Interaction

CS 6750 Section A Fall 1999

Final Exam

Part 1: Project/Peer reviews

On a separate piece of paper, please rate on a scale of 1 (lowest) to 100 (highest) the following factors relating to your group project. Your input will remain confidential, so please be honest in your appraisals. The input from this assessment will help determine cases in which extraordinary individual effort should be recognized (both positively and negatively).

• Rate the overall quality of the work of your project.
• For each individual in your project team, including yourself, rate the overall contribution of that individual to the project as a whole. In making your assessment, include issues such as responsibility, dependability, sharing of workload, intellectual contribution, and promotion of team morale.
• If there are any special comments or considerations you would like the instructor to be aware of in your project team, please provide that input as well.

Part 2: HCI Design and Evaluation (100 points)

Question 1 (50 points) CSCW support for Classroom 2000

• Provide support for dynamically-defined study groups. By dynamically-defined, we mean study groups that can be formed opportunistically based on features such as who is currently studying lecture notes or based on common interests or concerns.
• Provide support for anonymous feedback to other students and to the lecturer on the content and quality of the content of captured lectures. For instance, this feedback could be used to inform a lecturer of parts of a lecture that should be modified the next time this topic is taught, or to inform current or future students of important points that should be remembered.

1. (20 points) Write a scenario that addresses in more detail each of these two high-level goals. Each scenario should reveal enough information so that the reader can understand exactly how you anticipate the services would be used for a class similar to CS 6750. You may use diagrams (hand-drawn are acceptable) to assist your scenario description and you should assume that your services are contained within the existing interface for captured lecture notes.
2. (10 points) Classify these two group-related services, as defined by your scenarios, in terms of the time/space matrix and people/artifact frameworks introduced in class.
3. (10 points) You have limited time to prototype, evaluate and deliver these modifications to the system, and you decide that you will only be able to work on one of these services. Discuss how you would go about determining which service to work on.
4. (10 points) Pick one service and determine the three most important usability or usefulness criteria for that service. Justify why those criteria would be the most important and then sketch out an evaluation plan that would help you in the formative stages of design to produce a prototype that best meets those criteria.

Question 2 (50 points) Information appliances for the home

1. (10 points) User scenarios developed by the company identify three types of users. What features of the proposed device best support the needs of each user population? If you think that some important features are missing for any of the three suggsted user populations, indicate what those features might be.
2. (20 points) Pick one user population and perform a critique of the prototype that assesses its suitability for that group of users. This critique should indicate both positive and negative aspects of the prototype from the perspective of that user population. You should support your critique with evidence you have gained from this course through lectures and/or your experience with your own group project.
3. (10 points) How would you modify this prototype to better support the user population you identified above? How would you conduct a study to determine whether your revised prototype was better or worse for that user population when compared with the existing prototype?
4. (5 points) How might this information appliance be improved through the addition of some general ubiquitous computing features, as discussed in lecture (natural interaction, context-awareness, automated capture)?
5. (5 points) The software platform used to develop this information appliance allows the design team to add more features and capabilities to the eMailBox. For example, daily TV listings could be added on the front screen and constantly available for perusal of the current day's offerings on cable. Or, access to a travel Web site could allow for easy downloading of directions to any place in the city from the owner's home. Discuss the pros and cons of adding more functionality like this to the eMailBox appliance.
