1. Responsibility for an accident is rarely clearly defined and able to be traced to one or two individuals or causes. In this fictitious case, it is clear that a larger number of people share responsibility for the accident. Identify all the people who you think were at least partially responsible for the death of Bart Matthews, and why you think so?
*For me Randy Samuels is the responsible about the death of Bart Matthews because Samuels wrote the flawed software that caused a Silicon Techtronics Robbie CX30 industrial robot to crush and fatally injure its operator, Bart Matthews. Matthews was a robot operator at Cybernetics Inc. According to Silicon Valley Prosecuting Attorney Jane McMurdock, Samuels misinterpreted a mathematical formula, "turning harmless Robbie into a savage killer."
*the killer robot had an ability to recognize Bart Matthews using the "visual profiling" software that Dr. John Erstwhile brought to the public's attention that Dr. Erstwhile stated emphatically that his software did not have the ability to recognize individuals, as it often the liberties with historical truth takes in order to produce an entertaining murder mystery that is rotted in history but it is not historically accurate. i would like to alert that the depection of Silicon Techchronics employees are intirely accurate anf factual. it is Sally Matthews, the murder of the husband anf her torrid love affair with Hank Alterman that his murder mystery deviate from the truth......
2. Imagine that you are the leader of a task force assigned to correct the problems uncovered by this accident. Develop your “top-ten” list of actions that need to be taken to avoid future problems. What process would you use to identify the most critical actions?
*Strive for consistency. As we shall see below, it is important for a user interface to be consistent on many levels. For
example, screen layouts should be consistent from one screen to another. In an environment using a graphical user
interface (GUI), this also implies consistency from one application to another.
*Enable frequent users to use shortcuts. Frequent users (or, power users) may be turned off by overly tedious procedures.
Allow those users a less tedious procedure for accomplishing a given task.
*Offer informative feedback. Users need to see the consequences of their actions. If a user enters a command but the
computer does not show that it is either processing or has processed that command, this can leave the user confused and
disoriented.
*Design dialogues to yield closure. Interacting with a computer is somewhat like a dialogue or conversation. Every task
should have a beginning, a middle and an end. It is important for the user to know when a task is at its end. The user needs
to have the feeling that a task has reached closure.
*Offer simple error handling. User errors should be designed into the system. Another way of stating this is that no user
action should be considered an error that is beyond the ability of the system to manage. If the user makes a mistake, the
user should receive useful, concise and clear information about the nature of the mistake. It should be easy for the user to
undo his or her mistake.
*Permit easy reversal of actions. More generally, users must be permitted to undo what they have done, whether it is in
the nature of an error or not.
*Support internal locus of control. User satisfaction is high when the user feels that he or she is in control and user
satisfaction is low when the user feels that the computer is in control. Design interfaces to reinforce the feeling that the
user is the focus of control in the human-computer interaction.
*Reduce short-term memory load. Human short-term memory is remarkably limited. Psychologists often quote Miller's
law to the effect that short-term memory is limited to seven discrete pieces of information. Do everything possible to free
the user's memory burden. For example, instead of asking the user to type in the name of a file which is going to be
retrieved, present the user with a list of files currently available.
3. If you were in Ms. Yardley’s position, what would you have done when Rays Jonhson told you to fake the test result? How would you justify your decision?
*If I'm in Ms. Yadley' s position i will not allow the fake result for the safety or the workers because we don't know what is the result of that program.
