An information processing system includes a host system that samples coordinates indicated by using an input device to acquire a background image, and a controller that displays an output image based on the background image on a display medium. The host system notifies the controller of the coordinates. The controller updates the background image with an update cycle longer than a sampling cycle of the coordinates, and outputs the output image with a cursor placed at the coordinates on the background image to the display medium.

Information processing system, display device, and control method

An information processing apparatus includes a touchscreen display that detects, as a detection position, contact of an object on a screen of the touchscreen display and a processor coupled to the touchscreen display. The processor is programmed to acquire a plurality of first detection positions on the screen, calculate a movement parameter representing a movement of the object during the detection of the plurality of first detection positions, and select based on the movement parameter a first smoothing algorithm or a second smoothing algorithm. The first smoothing algorithm and the second smoothing algorithm are different from each other in a processing delay between detecting a particular detection position and output a smoothed detection position corresponding to that particular detecting position. The touchscreen display displays a movement locus on the screen based on the selected smoothing algorithm.

Information processing apparatus and control method

An information processing apparatus includes a display unit, a touch sensor disposed on the display unit and detects contact with an object on the display unit, a main system, and an embedded system. The embedded system generates image data of an input area for a virtual input device, output image data of the input area to the main system by using a first general-purpose interface protected by the main system, and output input information, which is based on detection information detected in the input area by the touch sensor, via the virtual input device to the main system by using a second general-purpose interface protected by the main system. The main system displays, on the display unit, the image data of the input area output by the embedded system.

An information processing apparatus includes a display, a touch sensor disposed on a screen of the display unit detects an input position by an input medium on the screen, a main controller, and an embedded controller. The embedded controller predicts a subsequent input position of the input medium based on detected input positions of the input medium detected by the touch sensor at predetermined detection intervals, and output, to the main controller, the predicted subsequent input position as part of the detected input positions detected by the touch sensor. The main controller, based on the plurality of detected input positions received from the embedded controller, display a movement trajectory of the input medium on the screen.

Information processing apparatus, information processing system, and control method

An information processing apparatus includes: a display; a touch sensor on the display that detects a contact with an object on the display; a main system that executes processing in accordance with an operating system (OS); and an embedded system different from and independent of the main system. The embedded system causes the display to display third image data obtained by synthesizing first image data output from the main system and second image data that is image data in an input area for a virtual input device, and to output input information based on detection information detected by the touch sensor in the input area to the main system as input information accepted by the virtual input device.

A method and program product can also perform the functions of the apparatus.

False input reduction systems, apparatus, and methods for an information processing device

Provided is a technique to enhance security of a computer in a multi-OS operating environment. A memory image of a primary OS is in an active state, and a memory image of a secondary OS is in a non-active state. When switching is performed from the primary OS to the secondary OS, a runtime image is created, and a digest P is calculated and encrypted (C). When switching is performed from the secondary OS to the primary OS, a digest of the stopped runtime image is calculated. Only when comparison between the decrypted digest P and the calculated digest shows agreement, is switching of the primary OS allowed.

Verifying integrity of backup file in a multiple operating system environment

Provided is a manner of switching between the operating environment of a primary OS and the operating environment of a secondary OS. In certain embodiments, a HDD keeps a runtime image of the secondary OS generated in a system memory. A DMA space for allowing the secondary OS to operate is formed in a physical address space where a memory image of the primary OS is active. The runtime image of the secondary OS is transferred to the DMA space. The operation of the memory image of the primary OS is stopped and the runtime image of the secondary OS is executed in the DMA space. Before activating the memory image of the primary OS, the runtime image of the secondary OS is saved to the HDD again.

Operating environment switching between a primary and a secondary operating system

The invention provides a method for a portable electronic device such as a computer to be capable of safely coping with the occurrence of a surprise removal from an external hard disk drive (HDD) connected by wireless. An HDD is connected to a portable computer by wireless via a wireless extension device. First, a wireless communication path between the HDD and the portable computer is configured. Subsequently, a file is read and edited by accessing the HDD from the portable computer. Next, removal information indicating that the portable computer is away from the HDD is produced. The removal information can be produced by detecting an acceleration generated in the portable computer, or by directly detecting the distance by the strength of the wireless signal. Data under editing is saved before occurrence of surprise removal by ejecting the HDD in response to the production of the removal information.

Methods and arrangements for accessing wirelessly connected external storage devices

The present invention provides a method of easily managing two or more OSs. A host OS, a guest OS, and a virtualization module are loaded into a primary physical address area of a main memory. The guest OS is executed in a virtual environment in a primary physical address area. A memory image of the guest OS loaded in the primary physical address area is copied to a secondary physical address area. The right of access to a processor is transferred to the guest OS copied in the secondary physical address area to execute the guest OS in a physical environment.

Operating system management of second operating system

The present invention protects a memory image of an OS in a sleep state. A CPU executes a first OS or a second OS while switching there between. The first OS is loaded into a main memory, and the second OS is loaded into an auxiliary memory. The auxiliary memory may be connected to a chipset through a PCIe interface. The main memory and the auxiliary memory are configured such that, when one is in an active state where the right of access to the CPU is obtained, the other makes a transition to the sleep state where there is no right of access to the CPU while maintaining the memory image. In order to prevent one OS in the active state from accessing the main memory or the auxiliary memory in which the memory image of the other OS in the sleep state is stored, the BIOS may set a corresponding controller to disabled during a POST.

Utilization of the screen image information of a primary environment for reproduction and user-interaction in a secondary environment

In the context of computer systems, the generation of preboot passwords at a server instead of at a client. Preferably, preboot passwords generated at the server are distributed to the client, and a process is offered whereby a user can establish his/her own proxy, not known to the server, that can be used to release the stored passwords to the client hardware. Since the passwords are generated at the server, management of the passwords is greatly facilitated since they are generated at the site where they are stored. This also makes it easy to implement management features such as a group policy, since the password generation software will be able to make logical connections between users and hardware.
