For off-campus teaching and counseling institutions, when they are looking for the teaching display device, like the training projector, they need to consider more about the friendliness of the equipment for students' eyes and the degree of portability used by students and teachers. In this part, let’s know more about them. As the person in charge of procurement of an education and training institution, how to combine the two factors to choose a suitable teaching display device.
(1) The friendliness of teaching display device to students' eyes - Eye protection
According to the "2022 China-Europe White Paper on International Myopia Surgery" jointly issued by Aier College of Ophthalmology and Aier Ophthalmology Institute of Central South University, there are currently about 2.5 billion people with myopia in the world. The incidence of myopia in Asia is higher than that in Europe and the United States. From the perspective of age, myopia surgery population in China tends to be younger, with an average age of 25.5, and students aged 20-24 account for the highest proportion, exceeding 40%. European myopia surgery population tends to be more professional, with an average age of 33.3, and the "office workers" from 25 to 29 years old accounts for the highest proportion, reaching 26%.
For students who need to use their eyes for a long time during their academic career, a new projection display device is more friendly to their eyes than an electronic whiteboard. Because the imaging method used by the electronic whiteboard is direct light, the light source can directly hit the students' eyes. However, the educational projector projects the light source onto the curtain or wall, and the light diffuses through the curtain and wall and enters the eyes. The diffuse reflection imaging method of the projector can make the brightness of the light softer and reduce the stimulation of light to the human eyes. This is one of the main reasons why the training projector is more eye-friendly than the electronic whiteboard.
(2) Portability of Teaching Display Devices - Interactive projector
A teaching display device with interactive functions will be more convenient to use than traditional blackboards and electronic whiteboards without interactive functions. Teachers or trainers often need to make annotations in the classroom and interact with students at any time. Most traditional blackboards and general electronic whiteboards do not have interactive functions, and it is difficult for teachers and students to interact well.
In contrast, HOTUS HT1500 interactive projector can better allow teachers and students to interact in the classroom, because it supports pen touch or hand touch, supports video and sound recording within 6 meters, and comes with 360° Rotating high-definition camera and digital microphone pickup array, which are very convenient and efficient for teachers and students who often need writing at anytime.
At the same time, the interactive projector allows students to freely write, draw, zoom, erase, save, etc., as well as freely save the written content. This process will allow students to enter an immersive learning state, which make it possible for learners to actively absorb more knowledge and improve their practical skills.
To sum up, for teaching counseling institutions and training institutions, a projector with interactive functions will be more popular with teachers and students.
