In recent years, virtual reality has moved from science
fiction movies, to academic research labs, to product development in the
industry, and finally into the hands of consumers in the real world. A number
of marquee devices have been launched in the market along with some compelling
immersive applications. At the same time, some cool augmented reality devices
and developer kits have been released as well. The pace of progress in both
virtual and augmented reality technologies has been rapid.
So, in line with this fast-emerging trend in the ecosystem,
SID decided to create a special track on Augmented and Virtual Reality for Display Week 2016. The rich lineup included a short course, a seminar, a number
of invited and contributed presentations in the symposium, and demonstrations on the exhibit floor.
It is just what the display industry needed to be on the
verge of a massive rejuvenation!
Displays are the face of some of the most used electronic
devices in our daily lives – such as the smartphone, tablet, laptop, monitor, and TV, among numerous other examples. As such, the health of the display industry
rises and falls with the growth and saturation of these devices. Take the exciting
phase of innovation in LCD TV technology as an example. The screen size went from
24 in. to 32 in. to 40 in. to 55 in. to 80 in. and above! The resolution went from 720p to
full HD to QHD and beyond, whereas the frame rates went from 60 to 120 frames
per second. And there were many more advances – contrast, brightness, color, etc. However, it
gets to a point where further advances in display technology provide only
small incremental benefits to the consumer. This often leads to a reduced demand
for new features and a slowdown in the development.
Let’s now turn to virtual reality. It’s a completely
different story at the moment. The displays on the best, state-of-the-art, VR
devices today fall way short of the specifications required for truly immersive
and responsive experiences, despite the dizzying pace of development. The pixel
density needs to increase significantly and latencies must be reduced drastically,
along with many other improvements such as increased field of view, reduced
pixel persistence, higher frame-rates, etc. Besides the display, the systems
also require integration of accurate sensing and tracking technologies. Augmented
reality devices impose additional requirements.
So this is exciting for the researchers and engineers in the
industry. Back to solving some difficult challenges, with the potential for big
returns. Judging by the excellent quality of the papers, presentations, and
exhibitions at the Display Week, it’s obvious the display ecosystem is all
geared up. Game on! – Achin Bhowmik
