This invention relates to methods and apparatus for improving communications between humans and devices. The invention provides a method of modulating operation of a device, comprising: providing an attentive user interface for obtaining information about an attentive state of a user; and modulating operation of a device on the basis of the obtained information, wherein the operation that is modulated is initiated by the device. Preferably, the information about the user's attentive state is eye contact of the user with the device that is sensed by the attentive user interface.

Method and apparatus for communication between humans and devices

The disclosed technology, in certain embodiments, includes a method and system for displaying messages in a wide-spectrum display includes a visible element comprising a first portion of a message and an invisible element comprising a second portion of the message. In one aspect, the method includes the step of displaying, in the visible element, e.g. an image from a film, a captured photograph or a first part of an advertisement. In certain embodiments, content may be displayed in the invisible element including, for example, subtitles, metadata or a second part of an advertisement. An individual may choose to view the invisible element by viewing the wide spectrum display through a wavelength conversion device. Also disclosed are the use of the display in games, and of its integration in wearable material.

Methods and systems for displaying a message in a wide-spectrum display

A method and apparatus for eye gaze tracking in human or animal subjects without calibration of cameras, specific measurements of eye geometries, or tracking of a cursor image on a screen by the subject through a known trajectory. One embodiment provides a method for tracking a user's eye gaze at a surface, object, or visual scene, comprising: providing an imaging device for acquiring images of at least one of the user's eves: modeling, measuring, estimating, and/or calibrating for the user's head position: providing one or more markers associated with the surface, object, or visual scene for producing corresponding glints or reflections in the user's eyes; analyzing the images to find said glints or reflections and/or the pupil: and determining eye gaze of the user upon a said one or more marker as indicative of the user's eye gaze at the surface, object, or visual scene.

Method and apparatus for calibration-free eye tracking

Apparatus and method for eye gaze tracking in human or animal subjects without calibration of cameras, specific measurements of eye geometries or the tracking of a cursor image on a screen by the subject through a known trajectory. One embodiment includes one uncalibrated camera for acquiring video images of the subject's eye(s) and optionally having an on-axis illuminator, and a surface, object, or visual scene with embedded off-axis illuminator markers. The off-axis markers are reflected on the corneal surface of the subject's eyes as glints. The glints indicate the distance between the point of gaze in the surface, object, or visual scene and the corresponding marker on the surface, object, or visual scene.
