A user of a computing device may interact with and control objects and applications displayed on the computing device through the user's eye movement. Detected gaze locations are correlated with actions performed by the user and compared with typical gaze locations for those actions. Based on differences between the detected and expected gaze locations, the eye tracking system can be recalibrated. An area around a gaze location encompassing a set of likely active locations can be enlarged, effectively prompting the user to interact with the desired active location again. The enlarging of the area serves to separate the active locations on the screen, reducing the probability of interpreting the user's gaze incorrectly.

The invention comprises a mechanical handwriting system linked to a user input system to generate a plotted document, such as a greeting card, note card or document, using a conveyor belt unit to support and move the document, a plotter, and a series of rollers to position and constrain movement of the greeting card, which is optionally and preferably linked to a paper feeder system in an assembly line format, where the rollers are optionally and preferably adjustable in position to accommodate varying paper sizes and to allow movement of the document during a plotting period to avoid positional overlap constraints of the rollers and a plotter head of the plotter in a process of plotting the document/card in sections.

A system, method, and non-transitory computer-readable information recording medium displays information to a user. Market data having a first portion and a second portion is displayed on a display unit of a trading device. A user focus area is detected, at the trading device. The user focus area is associated with one of the first and second portions of the market data. A first priority is assigned to the one of the first and second portions of the market data and a second priority is assigned to another one of the first and second portions of the market data. The first priority is higher than the second priority. The market data in the first and second portions is updated as a function of the first and second priorities, respectively.

Systems and methods that help ensure that content on a webpage is read and understood by analyzing user activity on a graphical user interface are described. As a user views and interacts with a webpage, activity of the user is monitored. For example, data associated with eye movement, brainwave activity, lip movement, eyebrow movement, and/or forehead wrinkling is collected. This data is then analyzed to determine if the user read and understood the content presented. Should the user fail to read and/or comprehend the content, the user may be alerted and/or prevented from proceeding or accessing additional content.

A device may include a control unit to control determination of a processing mode of at least two processing modes and in which an application is executed. The at least two processing modes may include a first processing mode in which the application is executed based on first identification information directly indicating the application and a second processing mode in which the application is executed based on second identification information indirectly indicating the application, where the first identification information and the second identification information are transmitted from an external device through a communication channel.

The present disclosure discloses methods and systems for printing a document having pages with different margins. The method includes receiving a document having a plurality of pages for printing, wherein the document having a combination of pages to be printed in first pre-determined sheets and second pre-determined sheets. A margin value for each page of the document is automatically identified. Based on the identification, one or more pages having margin value greater than a pre-defined margin value is automatically identified. The one or more pages with greater margin value are marked to be printed in the first pre-determined sheets and the remaining pages are marked to be printed in the second pre-determined sheets. Finally, information is sent to a printer to print the one or more pages having a greater margin value in the first pre-determined sheets and to print the remaining pages in the second pre-determined sheets.

A device generates an operating procedure manual for software including a captured image of a screen displayed by the software. An image acquiring hardware unit acquires a plurality of captured images of a plurality of screens displayed by software in response to a plurality of operations with respect to the software. A dividing hardware unit divides the plurality of captured images into a plurality of captured image groups, to each of which at least one captured image acquired in response to at least one operation constituting a meaningful chunk belongs. A generating hardware unit generates an operating procedure manual including, for each captured image group, a captured image belonging to that captured image group.

A three-dimensional (3D) image rendering method for a heads-up display (HUD) system including a 3D display apparatus and a catadioptric system is provided. The 3D image rendering method includes determining optical images corresponding to both eyes of a user by applying, to each of the positions of the eyes, an optical transformation that is based on an optical characteristic of the catadioptric system, and rendering an image to be displayed on a display panel included in the 3D display apparatus, based on a position relationship between the optical images and the display panel.

A device and a method for performing automatic adjustment and optimization display for a visible area of a screen is provided. The method includes determining position information of a viewer and the screen according to a face recognition algorithm, and determining an optimal visible area for the viewer according to a human eye view range algorithm, and adjusting a visible area of the screen according to the optimal visible area to obtain a size and layout of the visible area most suitable for viewing by the viewer.
