Abstract

Disclosed are a system and associated method for selecting an illumination point within the content of a presentation, which is presented on a white/black board, based on tracking the presenter’s eye gaze, and then accordingly highlighting the content.

based on Presenter's Eye Gaze Point

The ideas presented in this disclosure begin with enabling arts and existing technologies for:

• Eye gaze tracking • Digital white/black boards • Laser pointers (i.e., used during speaker-led presentations)
• Highlighting products based upon human gaze

No system or method exists for automatically highlighting portions of the black/white board based upon the presentation content given by a live presenter and the gaze point of the presenter.

The solution presented herein addresses this problem in settings having the prescribed input and output sources. The input is the gaze point of the presenter on the presentation material, this is mandatory. Optionally, input includes the presentation material, a speech recognition module, and/or a digital version of the board. A digital version of the board might also require a connection from a backend server to the board or a version of the board that has been physically built with an illuminable surface (e.g., on top of underlying light emitting diode (LED) lights, etc.). The output is the automated illumination of the gaze point on the white/black board, optionally fine-tuned by the personalized gaze pattern history of the presenter, and the presenter's spoken

words, identified with a speech-to-word-identification technology.

The novel contribution is a system and associated method for selecting an illumination point within the content of a presentation, which is presented on a white/black board, based on tracking the presenter's eye gaze, and then accordingly highlighting the content.

When the presentation is projected through a digitally enabled smart board, the system can correct/enhance the bright zone based on the presenter's gaze history for the same material (e.g., current slide) and the input received from a speech processing system that detects the words matching that material.

The system brightens the board/screen an external laser pointer that focuses on the detected area for focus (i.e., hot area). Alternatively, the system can adjust the relative brightness of different portions of the white/black board, such as increasing the brightness of the lights underlying the base of the board (if the board is so constructed) or applying different brightness levels to different parts of the board (if the board digital).

The disclosed system and method assume the following technical components/assets/capabilities exist as necessary background:

• Eye gaze tracking algorithm • Camera
• White/black board; optionally, a digital version, and if digital, the board is
