select three interfaces, and consider how the teamwork application could be redesigned for each of these types. Use your imagination. How about using a tangible interface or even a drone to help remote students collaborate? Keep in mind that the application is planned to be used by distributed users. So, some interface types such as shareable may not be applicable to the design. Also, consider the research and design issues boxes for the interface types you choose. For each interface type you choose, please complete the following tasks:

a- write down the conceptual model of your design. For example, a description of how the system is organized and operates; a hypothetical scenario/use case of how the application should be used by students; metaphors and analogies used in your design, and so on.

b- sketch out your design. Three sketches showing how your design operates and flows are required.

After you finish the designs, please answer the following questions:

a- Compare the pros and cons of designing the application using the three different interfaces with respect to conducting group projects online. You should use the HCI concepts you have learned until now to do the comparison (e.g., usability, user experience, assumptions/claims, metaphors, cognitive processes, levels in the model of emotion, interface types, and so on).

b- Based on the above comparison, discuss which design/interface you prefer, and why?
