AI Technical Summary

Benefits of technology

This patented technology allows for easy control over how an opaque display looks on a screen during projection viewings without requiring constant eye contact or physical effort from users. It achieves this by providing a specialized system that uses various components such as cables, connects between different parts, guides, motions mechanisms, sprouts, balls, etc., along with sensory devices like pressure gauges and light detectable indicators (LID). By controllably moving these components back/forth within specific directions, it enables automatic focalization based upon factors like distance and direction. Overall, this innovation improves image quality while reducing human error associated therewith.

Problems solved by technology

The technical problem addressed by this patented technology relates to an improved way for users who want to see images displayed with projection devices without getting tired or distracted from their usual viewing angle due to limitations such as limited focusing ability caused by bulky displays that require manual alignment during image presentation. This helps improve usable experiences while still providing consistently focused content.
