1. Early I.D. (interaction devices) were typically text-based, with some type of keyboard for input and some electro-mechanical output devices, while newer UI using AR/VR and other technologies have made visual/graphical I.D. popular. What is the future outlook for I.D. based on other sensory (e.g., sound, touch, smell, taste) or multi-sensory input/output? Explore this topic on your own by reading relevant publications (e.g., papers similar to those listed in TC2 in our additional papers) and/or other online/printed material, and give some examples of such I.D. and classify them by the sensory category, input/output functions, and the I.S. each I.D. supports. Please cite the sources of the information/document you referenced.

2. What is the usability of an I.D.? What is the usability of a system that supports C&C (Communication and Collaboration)? How would you measure them? What are the primary differences in measuring usability for these two?

3. Using MOCA as your guide, select two specific types of C&C situations, and make and justify your decisions on appropriate I.S. and I.D. to support such C&C tasks.
