The embodiments of the disclosure provide a method for operating a mirrored content under a mirror mode and a computer readable storage medium. The method includes: enabling a touch capturing function on the smart device, wherein the touch capturing function intercepts a touch event inputted to the smart device; in response to determining that a raw touch event is intercepted by the smart device, translating the raw touch event to a first touch event and sending the first touch event to a host, wherein a display screen of the smart device is mirrored to a visual content shown by the host, and the first touch event triggers the host to report a second touch event happened in the visual content; disabling the touch capturing function and receiving the second touch event from the host; and performing a first operation in response to the second touch event and enabling the touch capturing function on the smart device.

A non-transitory computer readable medium stores a program causing a computer to execute a process. The process includes: generating a first path which represents positions on a medium specified by a digital pen; obtaining a second path which represents positions on the medium specified by the digital pen and which satisfies a predetermined condition; obtaining information for specifying an area on the medium, the area having a predetermined positional relationship with the second path; and erasing the first path in accordance with a positional relationship between the area and the first path.

A display having a touchscreen is coupled to a processor that acquires a plurality of first detection positions on the touchscreen at a predetermined detection interval by an operation medium, calculates a predictive position indicative of a predicted subsequent position of the operation medium based on the plurality of first detection positions, corrects the predictive position based on a plurality of second detection positions and a weighting value, the plurality of second detection positions being a subset of the plurality of first detection positions selected at an interval greater than the predetermined detection interval, the weighting value being based on an angle between at least latest three detection positions among the plurality of second detection positions, and displays, on the display, a trajectory line including the plurality of first detection positions and the corrected predictive position.

A visual field information collection method is capable of collecting visual-field information of a user wearing a head mounted display without applying a large calculation load to a processor. The visual-field information collection method to be executed by a processor includes arranging, in a virtual space in which a user wearing an HMD is immersed, a virtual camera that defines a visual axis for specifying a visual field of the user. The method includes determining the visual axis in accordance with one of a movement of the HMD and a line-of-sight direction of the user. The method includes determining whether or not the visual axis is moved from a predetermined first position to a predetermined second position. The method includes generating movement information representing that the visual axis is moved when the visual axis is moved from the predetermined first position to the predetermined second position.

An optical film includes a substrate, an absorption pattern and a scattering reflection layer. The substrate has a contact surface and a back surface opposite the contact surface, wherein the substrate allows a first light to pass and is made of a non-rigid material. The absorption pattern is arranged on the contact surface of the substrate to absorb the first light. The scattering reflection layer is arranged on the back surface of the substrate to scatter and reflect the first light to the contact surface of the substrate. The foregoing optical film enables an optical reader device to detect variations of the reflected first light, which is caused by deformation of the substrate, so that the corresponding force information can be obtained. A user input system including the foregoing optical film is also disclosed.

Pointing device like mouse or joystick comprises camera for capturing the display screen and image processing means for recognizing and tracking the pointing cursor icon or mark from the captured image and producing the pointing signal. The pointing device of present invention can be used with any type of display without and additional tracking means like ultra sonic sensor, infrared sensor or touch sensor. The pointing device of present invention includes mark outputting portion, camera portion for capturing the said mark outputting portion and image processing portion for recognizing the said mark outputting portion from the captured image and producing the pointing signal.

An image projection apparatus includes an image receiver; an image processor; a projection unit to project a projection image on a projection screen; a coordinate calculator to calculate coordinates of a point in the projection image when the point is identified by a coordinate input device; an interactive communication unit to perform communication related to the interactive input-output capability with the coordinate input device, and the external apparatus; an operation information converter to convert the calculated coordinates of the point and an operation information of the coordinate input device to an operation information for the image projection apparatus and the external apparatus; a distance calculator to calculate distance between the coordinate input device and the projection screen; and an input-action-reproducing determination unit to determine whether movement of coordinates of the point on the projection screen identified by the coordinate input device is reproduced depending on the calculated distance.

The information processor includes an input unit having an illuminating part and an image pickup part, and an input medium having an input surface on which inputting of information is carried out by the input unit which has position coordinates on the input surface coded by a dot pattern. The input unit irradiates light from the illuminating part onto input surface of the input medium. The irradiated light reflects off the dot contained in the dot pattern which is picked up by the image pickup part, and position information of the dot pattern is obtained. The input unit further has an input unit angular position measuring part that measures an angular position of the input unit when the light is irradiated. Based on corrected position information obtained by correction processing based on the angular position, input information, that is specified by the position coordinates is obtained.

An optical member and an image display device including an optical member having a support, an underlayer, and a wavelength selective reflection portion in this order, in which the wavelength selective reflection portion has wavelength selective reflecting properties, the wavelength selective reflection portion has a cholesteric structure which has a stripe pattern including bright portions and dark portions in a cross-sectional view of the wavelength selective reflection portion when observed with a scanning electron microscope, the underlayer absorbs invisible light, and a wavelength range where the wavelength selective reflection portion has wavelength selective reflecting properties overlaps a wavelength range of invisible light absorbed by the underlayer.
