  • Patent number: 11141061
    Abstract: Traditional cognitive load estimation techniques rely on raw pupil size alone which is often prone to confound with changes in illumination, errors associated with sensor devices and irregular oscillations of pupil under constant light conditions. Estimation of cognitive load finds application in many domains including optimum work allocation, assessing a work environment and medical diagnosis. The present disclosure employs frequency domain analysis of pupil size variations to estimate load imposed by a cognitive task. A cognitive load metric based on power and frequency relations at mean frequency of the variation in pupil size addresses cognitive load estimation based on pupil dilation, wherein the pupil dilation is captured by employing low cost non-intrusive nearables.

  • Patent number: 10628994
    Abstract: A head mounted display (HMD) for displaying images to a user includes a sensor unit configured to detect motion of a head of the user of the HMD. The HMD also includes one or more processors configured to, in response to the motion, reduce contrast in a peripheral area of an image displayed to the user from an original contrast of the image, the image having a foveal area and the peripheral area relative to the optical axis of the eye of the user, the contrast being least reduced in a first portion of the peripheral area closest the foveal area and being most reduced in a second portion of the peripheral area farthest from the foveal area.

  • Patent number: 10595732
    Abstract: A pulse wave detection device color converts a frame image of a moving image from RBG components to YIQ components, and identifies an eye section using the eye color of a user prepared in advance with a Q component. Next, the pulse wave detection device uses the Y values of the eye section to detect the brightness of the imaging environment. Then, the pulse wave detection device detects a pulse wave signal Qm on the basis of the average of the Q-values of a skin section in the frame image, corrects a change in the brightness by subtracting from Qm the average value Ye of the Y values of the eye section, and thereby outputs a post-brightness-correction Qm. As a result, a pulse wave can be successfully detected even if the brightness is changing because the user is moving in a vehicle or the like.

  • Patent number: 10575728
    Abstract: A method of discovering relationships between eye movements and emotional responses of a user starts with engaging the user in a plurality of tasks configured to elicit a predicted specific emotional response or allowing the user to experience a naturalistic environment with free-form social interactions. A first camera films at least one eye of the user recording a first time series of eye movements and a second camera films an outward looking view of the user recording a second time series of outward events perceived by the user. The first and second time series are sent to a computing device which compares the eye movements from the first time series and the outward events from the second time series. The computing device can then identify at least one relationship between eye movements that correlate to an actual specific emotional response.

  • Patent number: 10542927
    Abstract: A system and associated method for computerized rotational head impulse test (crHIT) to assess the semicircular canals of the human vestibular system clinically in patients with balance disorders. The system utilizes a rotary chair combined with a head mounted VOG system with head tracking sensors. The crHIT protocol uses the same physiologic principles as the known video head impulse test (vHIT). The crHIT utilizes whole-body rotation via the chair to yield a persistent controlled, repeatable, comfortable, reliable stimulus can be delivered while recording eye movements with video-oculogaphy.

  • Patent number: 10537240
    Abstract: This invention relates to a method for providing markers for evaluating and/or practising the visual field recognizable by an eye, and/or eyes, and/or visual system of a person. The method relies on the reporting of the person of identifications of fixation objects only identifiable when the eye or eyes of the person are accurately fixated on the fixation object. Accordingly active monitoring of a saccade, if a saccade triggering stimulus is employed; or smooth pursuit, if smooth pursuit triggering stimulus is employed, of the eye of the person is not needed for determining whereto to eye or eyes are fixated. The present invention also relates to the use of a system employing the method of the invention. The present invention further relates to a system for the method of the invention and a software product for the system.

  • Patent number: 10534202
    Abstract: The present technology relates to a wearable device and an electricity supply system that make it possible to reduce the stress on a user in relation to electricity supply. A power generating unit is provided on the external world-side surface or the eyeball-side surface of a contact lens-type wearable device. The power generating unit generates electric power by chemical reaction with a substance contained in a secretion or a body fluid of a user wearing the wearable device, and a power managing unit supplies the electric power obtained in the power generating unit to each part of the wearable device. Thus, the power generating unit performs electricity generation using the secretion or the body fluid of the user as fuel; thereby, electric power can be stably supplied, and the stress on the user in relation to electricity supply can be reduced. The present technology can be applied to a contact lens-type wearable device.
