PHOTO-SENSING ENABLED DISPLAY FOR STYLUS DETECTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240118773 titled 'PHOTO-SENSING ENABLED DISPLAY FOR STYLUS DETECTION
Simplified Explanation
The optical stylus system described in the patent application includes an optical stylus and optical sensing system that work together to determine various parameters such as target or touch location, centroid, hover distance, tilt angle, azimuth, and in some cases, the orientation and rotation of the stylus.
- Light illuminator and detector angular filters are used to limit the angles of illumination and detection to reduce false object detection.
- The stylus is a passive stylus with a surface that reflects light consistently regardless of tilt angle.
- The stylus can detect light at different modulation frequencies or emit light with different spectral distributions to determine stylus location.
Potential Applications
This technology can be applied in:
- Digital art and design
- Interactive presentations
- Virtual reality and augmented reality systems
Problems Solved
- Accurate and precise stylus tracking
- Minimization of false object detection
- Consistent performance regardless of stylus orientation
Benefits
- Enhanced user experience
- Improved accuracy in stylus input
- Increased efficiency in digital workflows
Potential Commercial Applications
- Graphic design software
- Educational technology
- Gaming peripherals
Possible Prior Art
One possible prior art could be the use of optical stylus systems in interactive whiteboards or touchscreens.

The patent application does not mention the power requirements or consumption of the optical sensing system, which could be crucial for portable devices using this technology.
Original Abstract Submitted
an optical stylus system including an optical stylus and optical sensing system that are together operative to determine one or more of the target or touch location, centroid, hover distance, tilt angle, azimuth, and in some instances the orientation and rotation of the stylus is disclosed. in some examples, light illuminator and detector angular filters are employed to limit the illumination and detection angles of light to minimize false object detection. in other examples, the stylus is a passive stylus with a surface that reflects light with a consistent angular reflection profile or reflected light pattern regardless of stylus tilt. in still other examples, the stylus can detect light at different modulation frequencies emitted from an array of light emitters in the optical sensing system, or the stylus can emit light and detect reflected light with different spectral distributions across the optical sensing system to determine stylus location.
