Week 11 - Class Exercise

Imagine a Theremin Duet or orchestra.

Generate concepts for consistently reproducing & representing 3D movement in space that allows a musical composition to be accurately played on a Theremin.

Producing a virtual Theremin by controlling with a mouse. Using MouseY to control the amplitude and using MouseX to control the frequency.

Pugh Matrix to compare concepts 
What criteria important to measure against?

Evaluate each choice against the criteria. There are three ways to do this:

Method 1: Establish a rating scale for each criterion. Some options are:

1, 2, 3 (1 = slight extent, 2 = some extent, 3 = great extent)

1, 2, 3 (1 = low, 2 = medium, 3 = high)

1, 2, 3, 4, 5 (1 = little to 5 = great)

1, 4, 9 (1 = low, 4 = moderate, 9 = high)

Make sure that your rating scales are consistent. Word your criteria and set the scales so that the high end of the scale (5 or 3) is always the rating that would tend to make you select that option: most impact on customers, greatest importance, least difficulty, greatest likelihood of success.

Method 2: For each criterion, rank-order all options according to how well each meets the criterion. Number them with 1 being the option that is least desirable according to that criterion.

Method 3, Pugh matrix: Establish a baseline, which may be one of the alternatives or the current product or service. For each criterion, rate each other alternative in comparison to the baseline, using scores of worse (–1), same (0), or better (+1). Finer rating scales can be used, such as 2, 1, 0, –1, –2 for a five-point scale or 3, 2, 1, 0, –1, –2, –3 for a seven-point scale. Again, be sure that positive numbers reflect desirable ratings.
