1. (3 points) Try to find a recent paper about AR or VR, study it and summarize the paper in your own words. Pay special attention to how the DM decisions/principles are applied to the specific system/technology you studied. Your summary and discussion should be about 1-2 pages.

2. (3 points) What are the similarities and differences between menus and forms? Describe some general situations, supported by at least a couple of specific examples, where menus or forms may be more appropriate than direct manipulation.

3. (4 points) Command language interface (CLI) is one of the oldest UI. On the other hand, in pursuit of universal usability, CLI can be enhanced in various different ways, leading to multi-lingo natural language interface (NLI). Research advances in AI in general, and in NLP (natural language processing) and MT (machine translation) in particular, have contributed to NLI capabilities and our goal of universal usability. Will the advance of NLI eliminate the need for CLI? What is the impact on universal usability? Are there any limitations? Do you see a case for integration between NLI and CLI? How would you evaluate the usability of CLI and NLI? You may want to research this topic a bit by reading a couple of recently published papers on this topic. If so, please cite the paper in your answer.

   Your answer should be in the form of a short essay (or a short research paper) around 2 pages.
