A projection position guiding method adapted to a projection system is provided. The projection system includes a projection target, an image capturing device and a projector. The projection position guiding method includes: projecting a projection content onto the projection target by the projector to generate a projection image, the projection content includes multiple positioning grid points arranged at intervals; capturing the projection target by the image capturing device to generate a captured image, and the captured image includes at least part of the projection image; and determining whether the positioning grid points satisfy multiple recognizable conditions according to the projection image in the captured image, when it is determined that the positioning grid points include at least one unrecognizable grid point that does not satisfy at least one of the recognizable conditions, adjusting a color of the at least one unrecognizable grid point in the projection content.

Projection position guiding method

A projection system and a projection method are provided. The projection system includes a first projector and a second projector. A first projection image projected by the first projector and a second projection image projected by the second projector are partially overlapped. A projection region edit menu is executed to display multiple adjustment points and multiple connecting lines on the first projection image. A position of a selected adjustment point among the multiple adjustment points and positions of two connecting lines connected to the selected adjustment point among the multiple adjustment points displayed on the first projection image are changed according to a first moving instruction to select a closed region formed by the multiple connecting lines in a non-overlap region of the first projection image. The projection method is adapted to the projection system that provides a blending projection effect of multiple projectors having an even brightness.

Projection system and projection method

A projection positioning system and a projection positioning method thereof are provided. A projection device projects a first test image and a second test image on a projection screen based on a projection range at different time points. At least one photosensitive element is disposed on the projection screen. In response to projecting the first test image, a computing device divides a first image sub-zone of the first test image according to the first image sub-zone corresponding to one of first optical parameters sensed by the photosensitive element, to generate the second test image. In response to projecting the second test image, the computing device determines positioning information of the photosensitive element with respect to the projection range according to a second image sub-zone corresponding to one of second optical parameters sensed by the photosensitive element. The projection device performs a projection adjustment function according to the positioning information.

Projection positioning system and projection positioning method thereof

A touch display system, a touch device and a touch display method are provided. A first touch tool and a second touch tool are communicated with to determine whether the first touch tool and the second touch tool are enabled within an enable area. When at least one of the first touch tool and the second touch tool is enabled within the enable area, a touch light curtain generating unit is controlled to stop generating a light curtain. When the first touch tool and the second touch tool are all enabled, the first touch tool and the second touch tool are controlled to sequentially emit invisible lights, so as to determine touch positions of the first touch tool and the second touch tool, by which misjudgment of the touch positions is effectively avoided.

Touch display system, touch device and touch display method for avoiding misjudging of touch position

A projection screen includes a plurality of projection plates and at least one fixing component. Each of the projection plates has a projection surface and at least one connection side. Through the connection sides, the projection surfaces of the projection plates lean against each other to be coplanar. The fixing component includes two fixing sections connected with each other, wherein the two connection sides leant against each other are clipped at the two fixing sections, respectively.

Projection screen

An interactive projection system and a projection method thereof are provided. The interactive projection system includes a projection region, a projection device, a touch device and a host. The touch device is movably disposed on the projection region. The projection device projects a corresponding input interface on a touch sensing surface of the touch device according to a position of the touch device, so as to improve usage convenience of the projection system.
