![]() Signals from the head displacement sensors can be used to detect movement of the device relative to the user’s eyes. Methods and apparatus are described for tracking relative movement of a device with respect to a user’s head, in which sensors (referred to herein as head motion sensors or head displacement sensors) are placed at one or more locations in or on the device, such as at or in the Near the user’s ears to primarily track pitch, and at or near the bridge of the nose to primarily track y motion. The 3D models of the eyes indicate the 3D position of the eyes in relation to the eye tracking cameras, which allows the eye tracking algorithms run by the controller to accurately track eye movement. In some embodiments of an eye-tracking system, to accurately determine the position of the user’s eyes with respect to the eye-tracking cameras, the controller may run an algorithm that performs a three-dimensional (3D) reconstruction using images captured by the eye-tracking cameras to create 3D models of the generate eyes of the user. Today, the US Patent and Trademark Office officially granted Apple a patent entitled “Eye-tracking Using Low-Resolution Images” covering various methods and devices for eye-tracking in virtual and mixed or augmented reality applications (VR/AR) relates Head movement sensors known as “head mileage counters”.Ī key to providing accurate eye tracking is knowing the position of the user’s eyes in relation to the eye tracking cameras. Glint-enabled gaze tracking Event camera based gaze tracking with neural networks and more.Įye tracking with head movement sensors or “head mileage counters” the use of head movement sensors called “head odometers”. For those following the news of Apple’s future headset(s), there’s plenty to read here for in-depth details such as: B. The US Patent and Trademark Office has officially published a series of five newly issued patents covering various attributes that can be integrated into mixed reality headsets. Look offers industry-leading ease of use and customizations for improving user performance.Ĭombined with its sleek design, low power consumption and robust performance, Look is an ideal access method for a wide variety of individuals with disabilities requiring the use of eye tracking.Today was a big day for issued patents related to Apple’s future headset devices. Small and light, Look offers equal or enhanced performance over other solutions. ![]() Look also works well with eyeglasses and contacts under a variety of lighting environments, and allows for single- and two-eye use. Look has a variety of performance adjustments available for cursor movement, selection and custom interfaces, improving efficiency and ease of use during communicative interactions. For individuals with progressive neurological diseases, Look has a full range of calibration (0, 5, 7, and 9) and adjustment for speed of cursor movement, stability, dwell selection and timing to create a precise and accurate control required for extensive use for text, communication and control of the Windows environment. Look provides the refinement necessary for specific populations. The large track box provides freedom of movement and operation from a variety of positions, and combined with a very fast gaze recovery can be used seamlessly and continuously. PRC’s Look™ eye tracking module is a robust and potentially life-changing solution for children and adults who are unable to control a computer through more conventional means, such as a mouse or keyboard, or are unable to utilize other methods which require access through touch – for example, via a switch or touchscreen.
