CMSC 434            Homework #1            Spring 2005


Due Wednesday February 2nd.

Remote controls are notoriously difficult to use. Is there a reason?
For this first assignment, you must do the following:
  • Meet with at least four people who use remote controllers who are not computer science majors or faculty and talk to them about their experiences with remote controllers and their "wish list" for better remote controllers. Write a one to two page summary of their issues with current controllers and their desires for new ones.

  • Examine, explore, and redesign two remote controllers that you are familiar with. They can be used to control any device, except for remote controls that are designed for keychains (cars, alarms, etc.) The goal is to look at remote controls that control a fair amount of interaction complexity.
    Note: You can choose to examine video game controllers if they are intricate and allow for many options during the game but you can not do something such as "redesign" an N64 controller down to a joystick with a 'fire' button.

    You need to do the following for each of the remote controllers you select:
    • Write a half-page analysis for the control
      • For what tasks are the remotes used?
      • Who is the intended audience?
      • How well do they work?
      • What is difficult and what works well?
      • Make suggestions for improvements within likely real-life constraints (budget, production, size, etc.)
    • Show the "before" and "after" images for the control
      • Include a photocopy, picture or drawing of the original control.
      • Include a drawing (hand or computer-based) of the redesigned control.
  • Note: The pure artistic quality of your presentation of the "after" version will not affect your grade, but showing a clear effort at trying to make it look good will be a part of your grade on this homework. In other words, if you have difficulty drawing a straight line, use a simple "paint" program to help.
