is the sensor arrays that are likely to be used for consumer
applications in gesture control and Pyreos claims that the technology
can be tailored to provide appropriate accuracy at low power consumption
at the correct cost point for consumer equipment. However, the
technology will have to compete against CMOS image sensors that are
already in high volume production.
In the last couple of months
the company has appointed an international sales team and sales and
distribution partners in Asia to help it sell the Pyreos gesture sensor
product into mobile phone and tablet computer manufacturers in China,
Taiwan, Hong Kong and Japan.
"There is phenomenal interest in our
low-power gesture sensor in that region, which has intensified since
the introduction of the Galaxy 4 by Samsung which has gesture
functionality. Many customers have told us that they see our gesture
sensing as the lowest power and more long-term solution for mobile and
tablet devices that can work from close-up to a few meters of distance,"
said Jeff Gray, vice president of sales and marketing in statement
posted on the company's website.
Certainly an IR style sensor would be good for low-light recognition in a way that using a CMOS image sensor would not.
But one wonders how necessary gesture recognition would be for handheld devices. The use case in television and other more remote equipments is more obvious.
I wonder if the real reason for using IR is that it can obtain full illumination in light or dark without annoying the human user. A bright light coming from the sensor would be annoying - especially if people intended to be viewing a screen in the dark.
Sounds like a neat idea, I am left wondering about the details. What is the range, resolution for the sensor arrays and how much processing power is needed to support the gesture recognition? I would like to know more (please).

We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
