A speaker giving a presentation with an RF pointer in his left hand. Using a wireless clicker, helps the presenter to move freely, instead of being obliged to stay next to the computer, can get closer and keep in touch with the audience, watching the presentation together with them, being able to use the built-in laser pointer, in order to emphasize specific points in the dialogue with the ...
Industrial laser projectors have been on the market since the early 2000s. Laser projectors are mainly used as optical guidance systems. They enable working without templates in many manufacturing processes by showing directly on the workpiece how material needs to be positioned or mounted, so that the employee is led by manual or semiautomatic productional processes visually.
Beamer is a LaTeX document class for creating presentation slides, with a wide range of templates and a set of features for making slideshow effects. It supports pdfLaTeX, LaTeX + dvips, LuaLaTeX and XeLaTeX. [1] The name is taken from the German word "Beamer" as a pseudo-anglicism for "video projector".
At a more advanced level, flip charts, slide projectors, and overhead projectors can be used for displaying prepared content. The use of prepared material often results in a neater and more accessible presentation. Laser pointers or sticks are often used to highlight a particular point of interest within a slide or image. Many manufacturers ...
A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens , but some newer types of projectors can project the image directly, by using lasers .
Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
A laser projection keyboard used with a tablet. A laser or beamer projects visible virtual keyboard onto level surface. It is a modern input device. A sensor or camera in the projector picks up finger movements. Software converts the coordinates to identify actions or characters. [1]
Combining a pico projector with a webcam, a laser pointer, and image processing software enables full control of any computing system via the laser pointer. Pointer on/off actions, motion patterns (e.g., dwell, repetitive visit, circles, etc.) and more can all be mapped to events which generate standard mouse or keyboard events, or user ...
