Information & Communication

Applying audio and video technology toward improved practicality and functionality is the key to developing information communication systems capable of matching the pace of accelerating progress.

Communicating important information quickly and efficiently is vital in busy public spaces where large numbers of people come and go at a dizzying pace. The innumerable repeated announcements and other types of audio and video guidance used in these spaces, while often taken for granted, are essential in helping people navigate these areas with a minimum of stress and confusion. Further, just as the evolution of powerful networks has freed our communications from conventional concepts of time and distance, dramatic advances in information technology daily expand our message exchange capabilities into increasingly sophisticated new scenarios. Amidst these advances, TOA combines technologies for Seeing, Hearing, and Communicating in unique and original ways to create information communication systems that are ever richer in amenity and convenience.
