TMG399x intelligent sensor modules offer a flexible,
highly-integrated implementation of touchless user interface and
display management features for smartphones, tablets and many other
consumer devices
ams AG (SIX:AMS), a leading provider of high performance sensors
and analog ICs, today released a new family of intelligent sensors
that integrate six key sensing functions including gesture
detection and Mobeam barcode emulation. The TMG399x product family
is ideally suited for touchless gesture control and display
management in smartphones, tablets and many other consumer
electronics on the market today.
Advanced gesture-recognition software developed by ams supports
a wide range of gestures, enabling touchless control for consumer
devices. Gesture detection utilizes four directional photodiodes to
sense reflected IR energy, then converts this data into physical
motion information including: velocity, direction and distance. As
sensors continue to proliferate in today’s mobile devices, support
for sensor hub architectures has become an important requirement to
enable optimum system performance.
The TMG399x gesture software currently supports optimized
Android drivers, and a fully-qualified gesture library is available
for the Qualcomm ADSP sensor core on the Snapdragon 6xx and 8xx
processor family for four-direction gesture, plus ALS, proximity,
and all the other standard features. The ams gesture software
offers expanded capability to include support for eight-direction
gesture, push button and taps, and work is in-progress to support
other industry-leading third-party sensor hub devices.
The gesture engine features automatic ambient light subtraction,
crosstalk cancelation, dual 8-bit data converters, power saving
inter-conversion delay, 32-dataset FIFO, and interrupt driven I2C
communication. It accommodates a wide range of gesture-detection
requirements, from simple North-South-East-West gestures to more
complex gestures, including simulated button pushing and taps.
Power consumption and noise are minimized with adjustable IR LED
timing and optimized gesture algorithms.
The TMG399x product family also integrates industry-leading
color sensors from ams. Accurate color management and light
intensity measurements are critical parameters for display
management in portable devices operating under a wide range of
light sources, including fluorescent, incandescent and sunlight.
Proximity detection, composed of the IR LED and sensor, is
optimized for object detection within 100mm and can be used to
simplify a product’s user interface, such as intelligent on/off
control of smartphone touchscreens. The proximity detection is
factory-calibrated to a distance of 100mm, eliminating the need for
OEMs to perform production-line calibration, and simplifying the
end-product manufacturing.
ams is making it easy for systems designers to integrate
e-commerce functionality into smartphones and portable electronics.
The TMG399x Mobeam barcode emulation enhances the e-commerce
capabilities of any mobile device by enabling smartphones to
transmit barcodes to any one-dimensional scanner at retail
points-of-sale (POS) terminals. IRBeam functionality allows the
device to emulate other optical transmitters or provide advanced
signaling using the internal IR LED. A versatile state machine
along with 128 bytes of RAM allows for a variety of optical
protocols to be generated.
“The TMG399x’s family of IR touchless gesture sensors provides
for an enhanced user experience. As consumer electronics - from
smartphones and wearables to home automation and control - offer
greater functionality, the ability to interact with these systems
will be greatly enhanced as these space-constrained devices are
able to recognize and respond to the user without the need to
handle or touch them,” said Russell Jordan, Senior Marketing
Manager at the optical sensor business unit of ams. “This tiny but
highly integrated and powerful sensor family truly introduces a new
dimension in man-machine communications. Technology continues to
advance where the interaction between man and machine will rely on
the fusion of multiple and complementary interfaces such as touch,
visual, audio, and touchless gesture recognition to provide a
seamless and intuitive interface between technology and the
user.”
Price & Availability
The TMG3993 and TMG3992 are in volume production now, and priced
at $2.50 for 1,000 pieces.
