Key Concepts:

Cone to rod ratio, laser pointer, distance sight test, estimation of distance in inches.

Experiment Overview:

Steven Goldstein from the College of Optics and Photonics is conducting an experiment to test the cone to rod ratio in human eyes. The goal is to determine the average propensity for density related to a laser shone on a wall, simulating a distance sight test. Participants are asked to estimate the distance a laser pointer moves on a wall in inches.

Methodology:

1. Laser Presentation: A laser pointer is shone on a wall for approximately 2-3 seconds.
2. Distance Estimation: Participants are asked to estimate, in inches, the distance the laser pointer appears to have moved.
3. Data Collection: The estimated distances are recorded for each participant.
4. Repetition: The experiment is repeated with a second set of laser movements, and participants again estimate the distance.

Results (Round 1):

• Subject 1: 3 inches
• Subject 2: 3-4 inches
• Subject 3: 3 inches
• Subject 4: 5 inches
• Subject 5: 5 inches
• Subject 6: 4 inches
• Subject 7: 5 inches
• Subject 8: 6 inches
• Subject 9: 2 inches

Results (Round 2):

• Subject 1: 5-6 inches
• Subject 2: 5 inches
• Subject 3: 6 inches
• Subject 4: 7 inches
• Subject 5: 8 inches
• Subject 6: 7 inches
• Subject 7: 8 inches
• Subject 8: 12 inches
• Subject 9: 11 inches
• Subject 10: 12 inches
• Subject 11: 10 inches

Data Analysis (Implied):

The collected data (estimated distances) will be used to analyze the average human perception of distance under the given conditions (laser pointer, wall projection). This analysis will likely involve statistical measures to determine the central tendency (e.g., mean, median) and variability (e.g., standard deviation) of the distance estimations. The results will provide insights into the relationship between cone to rod ratio and distance perception.

Conclusion:

The experiment aims to gather data on human distance perception using a laser pointer. The collected estimations will be analyzed to understand the average human propensity for density related to the laser, potentially correlating with cone to rod ratios in the eye. The findings could have implications for understanding visual perception and designing effective distance sight tests.
