SUMMARY

The discussion focuses on determining how skywriting created by drones appears to a viewer positioned 50 feet away, with the writing located 35 feet in height. The participants suggest using scaling techniques, such as creating a paper model or utilizing a word processor to experiment with font sizes. They emphasize the importance of readability and suggest that the size of the letters may need adjustment based on distance. The concept of similar triangles is introduced as a method to calculate the necessary dimensions for optimal visibility.

PREREQUISITES
  • Understanding of similar triangles and basic geometry
  • Familiarity with scaling models and visual representation techniques
  • Basic knowledge of font sizing and readability principles
  • Experience with word processing software for visual experimentation
NEXT STEPS
  • Research the principles of similar triangles for practical applications in design
  • Experiment with different font sizes in a word processor to assess readability
  • Explore techniques for scaling physical models for visual representation
  • Investigate lighting conditions and their impact on visibility for aerial displays
USEFUL FOR

This discussion is beneficial for event planners, drone operators, and designers involved in aerial displays or large-scale visual projects, particularly those focused on optimizing visibility and readability from a distance.

Suppose there's a writing made by many small drones,each carrying a light and together making a writing.

If the writing is placed at 35 feet height from the viewer and the length is 50 feet from the viewer,how will it appear to the viewer?
Is there any equation to find this out?

I know it depends on the lights and the weather too.I want the writing to be big and bright from a distance.Also let me know if there's any easier way to do this.This is a big project for me.Any help is appreciated.

I would scale it down with a paper model and see how it looks.

As an example, draw some letters on a piece of paper with height 17.5 cm and hold the paper 25 cm from your eyes.

Alternatively you could use a word processor to draw the letters on the screen and then you can change the font size to see how it looks with your eyes 25cm from the screen.

What font size should I use?
 
Experiment with the sizes and then measure them on screen. If you feel they are readable then you adjust your letter heights as needed. 35ft may be far larger than needed when viewing at 50 ft.

I meant The writing will start at 35 feet.Check the attached image again I modified it.
 
okay, its still the same idea though scale things down, make a model or look for some sign that's readable from a distance and pace off the distance and measure the letters height. This is a similar triangle problem.
