A non-transitory computer-readable storage medium stores a projection adjustment program which, when executed by a processor, causes a computer to execute a process relating to adjustment of projection operations of projection devices configured to perform position measurement and projection on a target object in a projection system including the projection devices. The process includes: causing a first projection device to project invisible measurement light onto the target object; causing a second projection device to receive reflection light reflected from the target object; judging a connection relationship of a projection range of the first projection device on the basis of the received reflection light; executing a process of the judging of the connection relationship on all processing target projection devices; and generating projection position information indicating a connection relationship between projection ranges of the respective projection devices and displaying the projection position information on a display unit.

A method to improve a user's experience operating within a multiple monitor configuration; the method for assigning a first color to a first display screen within a first monitor and a second color to a second display screen within a second monitor; partitioning a first shared border edge of the first display screen; determining that a mouse pointer satisfies a threshold of the first partitioned shared border edge on the first display screen; modifying, in response to the mouse pointer satisfying the threshold, the first partitioned shared border edge with the second color; and highlighting, in response to the mouse pointer moving to the second display screen, a second border boundary of the second monitor display screen.

A haptic keyboard of an information handling system comprising a coversheet to identify keys of the haptic keyboard, a contact foil and a piezoelectric element to receive an applied mechanical stress at a first key of the coversheet and generate an electric actuation signal. A processor executing instructions of a haptic smart typing assistance system to detect and anticipate a next letter of a word being typed and a controller to receive an instruction of the anticipated next letter and increasing force required actuate at least one key for a letter adjacent to the anticipated next letter, and to send a response haptic feedback control signal to the piezoelectric element to cause the piezoelectric element to generate a first haptic feedback at the first key if the anticipated next letter is selected and to generate a second haptic feedback if a typographical error is detected.

An e-paper display device including an e-paper display panel, a graphics library and a display controller is provided. The display controller is coupled to the e-paper display panel. The display controller is configured to receive a line segment input signal and call the graphics library, and then drive, using a set of signal waveforms, the e-paper display panel to display a line segment. The set of signal waveforms is generated according to the line segment input signal and the graphics library. The line segment includes at least one gray level. In addition, a method for driving an e-paper display device is also provided.

The present invention provides a method for driving personal input device. The method is executed by a display. The display is connected with a personal input device. A first processing unit of the display drives the personal input device. The display receives a first event message from the personal input device. The first processing unit processes the event message to give a first event parameter, and updates the status of a cursor in a display picture according to the first event parameter. In addition, the first processing unit processes the first event message to generate a second event message, and transmits the second event message to an electronic device via a display data channel/command interface (DDC/CI).

A stylus includes a processor that acquires first coordinate values in a pen coordinate system at an occurrence position of a pen event detected by a pen sensor and acquires second coordinate values in a device coordinate system at the occurrence position of the pen event. The processor uses a plurality of sets of coordinate value pairs to determine conversion parameters for converting coordinates from the pen coordinate system into the device coordinate system and uses the determined conversion parameters and a measured amount of movement of the stylus to calculate coordinate values of the stylus in the device coordinate system.

The invention provides an operation method for multi-monitor applicable to an electronic system including a plurality of monitors. The operation method for multi-monitor includes capturing a current image including a user by using a camera, calculating a current gaze direction of the user according to the current image, and determining a target monitor according to the current gaze direction of the user. After the target monitor is determined, the operation method for multi-monitor further includes moving an object to a display area of the target monitor. In addition to the operation method for multi-monitor, an electronic system using the operation method is also provided.

A cursor image detection comparison and feedback status determination method is disclosed. The method is based on a non-invasive data-extraction system architecture, and uses an image processing unit to perform detection comparison on a cursor image shown on an operation screen outputted from a machine controller. The method includes steps of obtaining cursor foreground and background images set by a user, and selecting an algorithm to process the cursor foreground and background images to generate a cursor mask, and reading a cursor image and applying the cursor mask on the cursor image for pattern comparison, transmitting information of a comparison result and a cursor feedback status to a software control system, so as to provide a correction system to perform a cursor process program and check whether the movement of the cursor meet a position controlled by a feedback and correction system, thereby completing closed-loop control for the cursor.
