Abstract: Disclosed are covers for a mobile phone including aspects that protect the phone from impact and/or provide shock absorbance characteristics. Covers can include one or more protrusions that reduce the contact surface to the phone and dissipate energy. Advantageously, the one or more protrusions work with intermittent spaces to provide shock absorbing characteristics and reduce the contact surface area between the cover and the phone. In some embodiments, the protrusions can include a soft-side rectangular shape, where the protrusions are placed in an ordered array in the back wall of a cover. In some embodiments, the one or more protrusions can include a row of x-shaped protrusions interspersed with air pockets along the inside wall of the cover.

Abstract: A system for eye-gaze direction detection is disclosed that uses an infrared light emitting diode mounted coaxially with the optical axis and in front of the imaging lens of an infrared sensitive video camera for remotely recording images of the eye of the computer operator. The infrared light enters the eye and is absorbed and then re-emitted by the retina, thereby causing a "bright eye effect" that makes the pupil brighter than the rest of the eye. It also gives rise to an even brighter small glint that is formed on the surface of the cornea. The computer includes software and hardware that acquires a video image, digitizes it into a matrix of pixels, and then analyzes the matrix to identify the location of the pupil's center relative to the glint's center. Using this information, the software calibrates the system to provide a high degree of accuracy in determining the user's point of regard.

Abstract: A subject's eye movement and pupil diameter are measured while the subject is exposed to visual stimuli. The apparatus and method utilizes an eye-look detector to determine a subject's visual examination of a presented image and by computer recording an analysis superimposes icons representing the lookpoints over the image. The apparatus and method are not only of value in running routine tests but also may be used for new experiments.

Abstract: A system for eye movement detection is disclosed that utilizes an infrared light emitting diode mounted coaxially in front of the lens of an infrared sensitive video camera for remotely making images of the eye of a computer operator. The reflected light causes bright eye effect which outlines the pupil as brighter than the rest of the eye and also causes an even brighter small glint from the surface of the cornea. The computer includes graphic processing which takes a video image, digitizes it into a matrix of pixels and analyzes the matrix. Using special algorithms the analysis determines the location of the pupil's center and the location of the glint relative to each other and with this information determines where the eye is gazing. If the eye-gaze is for a predetermined time at images in selected areas on the computer screen, the area is selected and results in actuation of other devices or the presentation of additional images on the screen.
