SUMMARY

The discussion centers on the use of horizontal/convex lenses in back projector systems to ensure correct information display on screens, such as car instrument panels. Users emphasize the importance of inverting the image in the horizontal plane to maintain the correct sequence for viewers. Additionally, some projectors offer a mirroring feature that can be toggled to achieve the desired display orientation without additional optical components. The conversation highlights the need for clarity in image presentation for effective user interaction.

PREREQUISITES
  • Understanding of optical principles, specifically lens types and their functions.
  • Familiarity with projection technology and back projection systems.
  • Knowledge of image inversion techniques in optical systems.
  • Experience with projector settings, particularly mirroring options.
NEXT STEPS
  • Research the specifications and capabilities of horizontal/convex lenses for projection systems.
  • Explore the settings and features of various projector models, focusing on mirroring functionalities.
  • Study optical image inversion techniques and their applications in display technology.
  • Investigate user interface design principles for back-projected information displays.
USEFUL FOR

This discussion is beneficial for optical engineers, projection system designers, and automotive display developers seeking to optimize information presentation in back projection scenarios.

Hi there. If there is to be a back projector system behind a screen (such as a car instrument panel), in order for the information to be displayed in the correct sequence I'm thinking some sort of horizontal/convex lens will need to be used in order to invert the information in the horizontal plane so that it is displayed in the correct sequence to the user on the other side of the screen.

Is there anything else (or any comment on the description above) that should be considered in order to produce the correct sequence of information?

Any help is appreciated.

Thanks!

You could just project it already mirrored so that it shows up the right way when you back-project it. I think some projectors have this as a setting you can toggle.
 
Thanks. Any other suggestions are appreciated.
