3. Envision a sundial; if you know the height of that sundial and the length of
the shadow, with some quick math, you can calculate that angle.
Additionally, if there are multiple sundials and they all produce
independent angles, you can then calculate the intersection.
As the light (or object) is moving, the shadows will also constantly be
changing.
Baanto’s ShadowSense technology can easily be used to track position in
3D by tracking 2D shadows.
4. This time envision two pixels side by side, P1 and P2. Half of P1 is covered
by a roof or an aperture.
When a light source is directly above, all the light will fall on P2, while P1 is
only exposed to half the light.
As the light begins to move in a clockwise direction, subsequently, P1 will
start to get more light.
And conversely, as the light moves in a counter-clockwise direction, P1 will
get less light.
What does this all mean? Well, looking at the ratio of the light on P1
versus P2, you can quickly determine the object’s position that is causing
the shadow.
5. How this works in ShadowSense
Touch Technology
With our next-generation IR-based ShadowSense touch technology, what
we have is a bunch of ShadowSensors along the top.
Baanto’s ShadowSensor is a patented sensor, which operates in the
analog domain and detects the angle of a ray of light based on the
shadow cast on the sensor.
When a finger or an object touches the screen, multiple shadows are cast
at different angles.
Each of the ShadowSensors calculates the angle of the shadow that falls
upon it. Keeping it simple, the intersection of the shadow tells you exactly
where the touch is.
6. ShadowSense can also determine the size and shape of the object which
can be used to decide if it was a touch, eraser, pen or stylus.
Additionally, the darker the touch, the more opaque the object; this allows
a straightforward resolve, whether the touch was intentional, accidental, or
water drop.
7. Conclusively, this is why Baanto’s ShadowSense next-generation IR-based
technology is entirely different from any other IR technology on the
market.
These innovations have resulted in products featuring some of the highest
performance, most robust, multi-touch capabilities available in the market
today.
