I’m in the Texas Instruments suite at CES 2025, where they are showcasing several automotive display innovations beyond CY Vision’s AR HUD (covered in a separate video). Here are the highlights:

1. Window Projection

• Demonstrated using an Appotronics projector (see separate video for details).
• Projects information onto the side window, useful for:
  • Displaying Uber driver details.
  • Showing safety alerts when backing up.
  • Other informational or entertainment applications.
• This concept has been shown by multiple companies, but TI emphasizes its flexibility.

2. Ground Projection (Puddle Projector)

• TI supports auto-qualified DLP products for this application:
  • 0.46-inch and 0.55-inch devices.
  • “Q1” in the part number indicates automotive qualification.
• Demo concept:
  • Uses a Bluetooth specification called Channel Sounding.
  • When you approach your car:
    • At a preset distance, the ground projector activates, displaying a welcome message or car logo.
    • At a closer range, you can unlock the car door using Bluetooth.
• Why Channel Sounding?
  • Offers customizable range settings.
  • Alternatives like RFID or Ultra-Wideband exist, but:
    • UWB is costly and power-hungry.
  • Channel Sounding provides a clever, efficient solution for proximity-based interaction.

Summary: TI’s demos highlight practical uses of projection technology—from window displays for information to ground projection integrated with smart Bluetooth features for enhanced user experience.
