Are you using 100% of your projector?
In many cases, when working with modern projectors, teachers and students use barely half of the potential hidden in them. Opportunities missed by a teacher include, for example, the following: to call a young artist with a request to demonstrate his work to students over the network in real-time; organize online lectures with a guest lecturer; Stream the projected image to students who are unable to attend classes due to illness, for example. All it takes is a creative approach and the right equipment.
The days when a cable was required to operate a projector are rapidly receding into the past, and many models now have built-in support for wireless technologies. Due to this, the so-called "one person - one projector" scheme of working with a projector is changed to a "many people - one projector" scheme.
There are three main methods for organizing wireless collaboration with a projector, each with its own pros and cons. Some technologies can significantly diversify the learning process, while others can complicate the already complex architecture of the solution and even, due to high prices for individual components, increase the cost of the entire system as a whole.
So, as already mentioned, there are dozens of projectors on the market that are originally equipped with support for wireless technologies. This trend continues to gain in popularity, although in lower-end projector models, the choice between WiFi and USB-based solutions is chosen in favor of the latter. A projector equipped with built-in WiFi support will allow you to transfer images from computers, phones, tablets and laptops to a head-up display, but you also need specialized software for this. By the way, some models of projectors from NEC and Epson also support wireless projection.
