Describe a perceptually perfect (i.e., efficient) visual display. Include in your discussion.



Answer:

A. Visual field- displays that use literally your entire field, as you go further away from periphery, you need to display things bigger to convey that info
B. Intensity range-ratio of intensity levels you can see
C. Number of intensity levels- 2^8 - 2^10 intensity levels (8-10 bits)
D. Visual acuity(100 lines or 50 cycles per pixel)
E. Temporal acuity- our refresh rate(1/20sec)- anything that flashes quicker than that, we would not notice it is flashing
F. Color- RGB triangle inside the CIE table,, we can only make colors inside the RGB trinangle
G. Motion-

What is JAD and how are users involved? What are advantages and disadvantages of JAD? Joint application development, is a popular fact finding technique that brings users into the development process as active participants. Users have a vital stake in the information system, and should participate fully in the development process. They are/should be involved at every stage of development. Advantages : Users can participate effectively in the requirements modeling stage. More accurate statement of systems requirements, better understanding of common goals and stronger commitment to success of the new project Disadvantages : More expensive, can be cumbersome if the group is too large for the project.

A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D.

A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D. Design an experiment, based on the principles of diffusion and osmosis, that the assistant could use to determine which of the flasks contains each of the four unknown solutions. Include in your answer (a) a description of how you would set up and perform the experiment: (b) the results you would expect from your experiments: and (c) an explanation of those results based on the principles involved. (Be sure to clearly state the principles addressed in your discussion.)
