Audiovisual means something that possesses both a sound and a visual component,like films,documentaries, and live theatre productions. In the field of communication,audiovisual systems and audiovisual technologies are used to get the word across through the means of multimedia. With time,the scopes of AV technology has surpassed its appeal to only optical and auditory senses to extend into augmented reality.
Where it all began
- The development of AV media has its base in visual media. It started to gain momentum, particularly in the post World War II world. The people who returned from the war had first-hand learning experience through the use of motion pictures and other forms of AV media and this invariably contributed to the acceleration of the advancement in the field at large.
- More and more people were aware of the advantages and effectiveness of learning from Audiovisual mediums. As more people from the generation of baby boomers began going to school, more schools were built that accommodated new AV equipment,giving rise to the necessity of technological and pedagogical support.
- Consequently,positions of building and district audiovisual coordinators were created. In 1947,the Department of Visual Instruction of National Education Association in the US changed its name to the Department of Audiovisual Instruction,which later evolved into what we know today as the Association for Educational Communications and Technology (AECT)
