Abstract

Systems, devices, apparatus, methods, and computer-readable storage media for developmental assessment using eye tracking are provided. In one aspect, a system for development assessment via eye tracking includes: a patient-side computing device having a screen for presenting visual stimuli to a patient, an eye-tracking device integrated with the patient-side computing device and configured to collect eye-tracking data of the patient while the visual stimuli are presented to the patient on the screen of the patient-side computing device, and an operator-side computing device configured to present a user interface for an operator to communicate with the patient-side computing device.

Core Innovation

The invention describes a computer-implemented method for using an infrared eye-tracker camera of a handheld eye-tracker console that is wirelessly controlled by an operator-side handheld computer physically untethered from the handheld eye-tracker console. The handheld eye-tracker console mechanically mounts a display screen and the infrared eye-tracker camera together and orients them in a same direction, and the operator-side handheld computer is portable to different locations relative to the handheld eye-tracker console.

While the operator-side handheld computer is wirelessly communicating with the handheld eye-tracker console via a cloud server, the method responds to a command input at the operator-side handheld computer. With the patient oriented toward the handheld eye-tracker console, the infrared eye-tracker camera, mounted adjacent to a periphery of the display screen, converts infrared-detected eye movements into a real-time data stream including pupil positions and gaze vectors, and the display screen presents a predetermined sequence of stimulus videos.

Subsequent to operating the infrared eye-tracker camera, the method automatically uploads, without human intervention, to the cloud server both a first file storing timestamped eye-tracking gaze coordinate data and a second file storing a playlist of the predetermined sequence of stimulus videos with associated timestamps. The cloud server supports linking session data to specific stimuli and processes the collected eye-tracking data for fixation and event detection and drift compensation or recalibration using reference or model data across patients.

The cloud platform outputs diagnostic or assessment results including a likelihood and multiple index scores or severity measures through an operator web portal, together with visualization of eye-tracking data over stimulus stills. The system also supports parallelized analysis, multi-tenant isolation, and operational availability features while communicating securely with the cloud server using network-based protocols.

Claims Coverage

The partial content provides one independent claim (clm-00001). The independent claim includes three inventive features: wireless cloud-mediated control with same-direction mechanical mounting, real-time infrared eye-tracking during a predetermined stimulus video sequence, and automatic upload of timestamped gaze data together with a stimulus playlist and timestamps.

Across the independent claim, the core inventive coverage centers on cloud-server-mediated wireless control of an untethered operator device, streaming real-time infrared eye-tracking data while presenting a predetermined stimulus video sequence, and then automatically uploading timestamped gaze coordinates together with the stimulus playlist and timestamps to the cloud server.
