Variations in color perception

In the variations in color perception test the materials used were a Toshiba notebook (Satellite A215-S4697), and included in the notebook is Microsoft Office (2007, Microsoft PowerPoint). After the test was set up materials needed to create the testing apparatus are cardboard boxes, duct tape, scissors (stainless steel), standard safety glasses (from Home Depot) and a glue stick (Permanent glue stick, acid-free, photo-safe, .26 oz.). For testing, a chair was needed ( 43.18 cm high chair) and a data student laboratory notebook to record information.

To start the variation in color perception test, the topic had to be research using a Toshiba notebook (Satellite A215-S4697), and collect data in the data student laboratory notebook (from macademix.com).

A survey for the participants was developed to record their age, gender, eye sight levels, eye glass status, and eye sight problems. Also, a form for the participants’ signature was created so the scientific fair committee would know they were not forced into anything and that at anytime during the experiment they could drop-out and be excluded.

After all of the data is collected, the color vision test was set up and created using the Microsoft PowerPoint 2007. The first step of the test gave directions so that the participants understood what they were doing. After that, the constant side was created and designed like left, left, right, for the colors red blue and green. While choosing colors, the RGB values were recorded the colors could be understood and differentiated when analyzing. They were as follows: Reds the constant Base: R: 225 B:0 G:0, slide number one R: 190 B:0 G:0, slide number two R: 250 B:0 G:0, slide number three R: 25 B:49 G:0, slide number four R: 255 B:48 G:59, slide number five R: 235 B:0 G:0, and slide number six R: 231 B:0 G:78. For the blues, the constant Base is: R: 20 B:30 G:200, for slide number one the rgb value is R: 75 B:30 G:200, for slide number two R: 0 B:0 G:178, for slide number three R: 35 B:30 G:200,for slide number four R: 87 B:30 G:200, slide number five is R: 20 B:96 G:200, and slide number six rgb value is R: 16 B:78 G:160. The green rgb values and constants are, the Base constant which is : R: 172 B:233 G:73, the rgb value of the first slide is R:144 B:216 G:26, the second rgb value is R: 151 B:227 G:27, the third slide R: 161 B:230 G:50, the fourth slide has the rgb value of R: 202 B:239 G:67, the fifth’s slide is R: 129 B:194 G:24, and the sixth’s slide is R: 107 B:99 G:107.

After the test was created the contraption to block light and keep the test constant had to be created. A cardboard box had to be cut into three pieces, one for each side of the computer approximately 53.34 cm for each pieces. There was also another 53.34 cm piece that was fastened with duct taped to the screen directly down the middle( 17.78 cm in from both sides) to create a split in the vision fields. Then the safety goggles were duct taped to the cardboard apparatus. This set up the testing apparatus. A chair would then be put in-front of the apparatus to create the testing station.

The staff at Bartlett Jr. Sr. High School in Webster, MA was contacted to see if testing could be conducted. The church in Marlborough, MA was also contacted to see if testing could be done also. After permission was granted to stat testing, information was gathered form the tests. The test in its entirety was descried to all of the participants. Surveys were then handed out and participants started the three minute test. After the school and the church testing was complete, the WPI campus in Worcester, MA was contacted to conduct more experimentation at the library. As testing was going on the data was entered into the log book. The data was then analyzed and put it into three separate graphs, on common graph with all of the information for ever age, one graph for females, and one graph for males. After all of the testing and analyzing was complete the information was typed up in Microsoft Word 2007. Then it was attached to the presentation plasterboard.

Next task was to gather my information, sorted it out and developed a speech and presentation for the judges. After the presentation was complete all that was left was to take it into school and go to the science fair.
