ShadowSense™ Features
What do you expect from your touch screen technology? Are you familiar with all of the benefits of incorporating ShadowSense™ into your devices? We want to educate you about the touch screen features that Baanto has to offer.
ShadowSense™ Performance & Reliability
Fast touch screen response time of 6 ms to 8 ms – that is independent of the number of touches. All touch calculations are performed in the controller, resulting in no host PC processor overhead.
ShadowSense patented technology provides an unparalleled degree of immunity to high brightness and changing light intensities. Completely immune to every type of light source using advanced band-pass filters at the sensor electronics level.
The ability to sense the size of the touch object allows ShadowSense to react instantaneously to an object such as a paintbrush.
Sensing the size of an object permits control over what is recognized as a valid touch, versus unintentional touch. Using the Baanto Dashboard, precise definitions of a valid touch can be programmed. This allows things such as palm rejection easier to control.
ShadowSense differs from all other technologies in that it senses the shadow of the object causing the touch. Because of this, we can also detect the density of the shadow. Being able to detect density allows us to tune out translucent touches or shadow touches, such as those caused by water.
With the unique abilities of ShadowSense, accidental touches or unintentional touches can be identified using parameters set by Baanto Dashboard. This makes for a highly reliable and satisfying user experience.
ShadowSense is capable of precisely identifying the different finger motions required for a click, click/drag and double click-through a multitouch input. It is possible to eliminate the confusion that Windows creates if the user does not provide a positive touch.
Unlike optical and IR systems, ShadowSense will not fail if portions of the screen are blocked, or if individual components fail. This high level of reliability reduces touch screen failures that bring about unresponsive touch screens, to virtually zero.
ShadowSense technology is completely immune to sunlight and will work perfectly under any environmental conditions 24/7.
ShadowSense has the ability to register a touch at some position above the surface of the screen. This is what is commonly known as hover touch or floating touch. The “hover distance” can be determined in Dashboard. By controlling this distance a touch can be initiated whilst not touching the screen, or the user can be “forced” to make positive contact with the surface.
ShadowSense can recognise the difference between a stylus, finger or eraser without having to make monotonous menu selections. Write with the pen, resize or move with fingers, erase with the eraser in a smooth and natural workflow. The sizes of the pen and eraser can be set and adjusted within the Dashboard for a multi touch object recognition.
ShadowSense can detect and track up to 10-20 (dependent on SKU) independent touch points simultaneously. The position, size and shape of all touch points are constantly tracked to provide a reliable and robust multitouch experience.
ShadowSense differs from all other technologies in that it senses the shadow of the object causing the touch. Because of this, we can also detect the density of the shadow. Being able to detect density allows us to tune out translucent touches or shadow touches, such as those caused by water.
By controlling the speed at which touches are recognized as being valid, accidental touches that happen quickly, such as the brush of a shirt cuff, can be eliminated. False touch detection, along with eliminating accidental touches based on size, works together to provide a precise profile of touch, increasing the reliability of use in high-reliability environments such as medical or aerospace.
ShadowSense is capable of precisely identifying the different finger motions required for a click, click/drag and double click-through a multitouch input. It is possible to eliminate the confusion that Windows creates if the user does not provide a positive touch.
The Dashboard provides comprehensive diagnostics for ShadowSense frames, giving immediate feedback of LED functionality. This allows for easy troubleshooting and quick servicing to reduce down time for critical applications. This also allows for remote monitoring applications.
ShadowSense provides a unique mode that allows it to operate in rain. It does this by rejecting touches from water based on transparency and by automatically calibrating itself to accommodate water that pools along the edges of the bezel.

Check out the complete list of features and corresponding benefits of ShadowSense:
| Features | Benefits |
| Does not need drivers or processor resources, and is a USB HID device | Compatible with most hardware and software platforms has fast response times of 6 to 8 ms. |
| Sensors come with a built-in notch and bandpass filters | Not affected by ambient light, and works well in changing light conditions or in direct sunlight. |
| Can sense the size and shape of the touch object | Can react instantaneously to soft bristles of a paintbrush while rejecting palms resting on the screen. |
| Can accept or reject touch-based characteristics | Watches, shirt cuffs or bracelets brushing against the screen won’t register any input, increasing the reliability of use in critical applications like medical and aerospace. |
| The density of the shadow made by the object can be detected | Touches made by water or other fluids can be tuned out |
| Has support for up to 10 touchpoints | Recognizes multi-touch gestures like swipes, pinch, flicks, tap, double-tap and drag. |
| Can accept touch by any device based on how the screen is configured, regardless of whether the object is a conductor of electricity | Accepts touch inputs by gloved fingers, fingernails, pens, keys, credit cards, styluses, erasers, etc. |
| Hover distance can be controlled | Touch events can be recorded even if the user’s finger does not touch the screen. Alternatively, users can be forced to touch the screen to register an impact. |
| 3mm thick tempered glass covers the screen, which has 91% optical clarity | A rugged screen that is scratch resistant, and which performs exceptionally well |
