Tenología para punteros sensibles a la presión

En EADTrust estamos recopilando información sobre las diferentes tecnologías utilizables en tablets basados en sistemas operativos Android y Windows, así como dispositivos diseñados para complementar tablets i-Pad de Apple.

Hay que aclarar que las tecnologías son interesantes porque definen el estado del arte en términos manejables (el número de tecnologías básicas es limitado) mientras que las implementaciones equivalen a un mundo inabarcable y cambiante de marcas y modelos, que, incluso, cambian de tecnología de una generación de dispositivos a la siguiente. Por ejemplo Surface-2 usaba tecnología Wacom mientras que Surface-3 usa N-trig.


maXStylus mXTS100 for Handsets and Tablets

The maXStylus mXTS100 provides advanced active stylus capability for touchscreen controllers based on Atmel’s maXTouch® E Series and future maXTouch technologies. This union simplifies touch system hardware and software while providing a state-of-the-art, inexpensive touch and stylus solution.

A single indium tin oxide (ITO) sensor interfaces with the maXTouch controller to detect finger touches and stylus proximity, simplifying the hardware for your application and lowering system costs. Through the system driver, the system host controller interfaces with the maXTouch chipset for touch and stylus data.

maXStylus™ mXTS200

«The maXStylus™ mXTS200 is designed to provide high-performance active stylus capability for maXTouch™ T Series touchscreen controller system. Atmel’s industry-leading maXTouch controllers can seamlessly support maXStylus without additional hardware components or design changes. These solutions include our recently launched maXTouch T Series devices ranging from the mXT640T to the mXT2952T single-chip solution. This integrated solution eliminates the need for an additional sensor layer, lowering overall system costs for the original equipment manufacturer (OEM) without compromising performance. The complete maXTouch and maXStylus solution has achieved Microsoft’s Windows® 8.1 certification. Atmel’s solutions can also be seamlessly integrated into Android or Windows 8.1 operating systems.

The mXTS200 uses capacitive sensing to detect an active maXTouch sensor presence and responds with its own signals to indicate location, pressure, button click timing, and other information. The maXTouch controller receives stylus information through the sensor while also detecting finger touches. After the maXTouch controller detects a stylus presence, special algorithms activate to process the stylus data to provide high linearity, accuracy, and resolution. Further processing provides excellent palm rejection, resulting in a smooth and comfortable stylus writing experience.»

Synaptics offers an active pen hardware design for OEMs looking to differentiate their high-end products with a bundled active pen solution or to generate new revenue streams with an aftermarket active pen upsell. The Synaptics active pen boosts performance significantly and brings the stylus experience closer to physical pen and paper than ever before. Users will see improved accuracy, seamless conversion between pen and finger inputs, and new levels of writing resolution in addition to new features such as pressure sensing, hover detection and active buttons for additional functionality.

“The integration of stylus digitizing directly into our latest touchscreen controllers is a significant design innovation and an achievement that we’re proud to be first-to-market with,” said Kevin Barber, senior vice president and general manager of the Smart Display Division, Synaptics. “Previously, adding active stylus support could warrant a significant budget increase for the OEM, but with our latest solution, this differentiating feature can finally be brought to the masses with no additional design costs and a level of performance that is far superior to what we’ve seen to date.”

Synaptics says that «sophisticated algorithms enable the inking of straight lines without jagged edges and curved lines that accurately follow the pen motion.» The system can detect hovering, too, and it’s smart enough to ignore inadvertent palm contact while the pen is in use.

Key features of Synaptics’ stylus support:

  • Buttons –The new solutions enable additional Windows 8.1 integrated features such as eraser and selection functions.
  • Enhanced Palm Rejection – Fingers or parts of the hand that lean on the screen will not be misinterpreted when the pen is in use.
  • Extreme Accuracy – Along with a fine 1mm tip, sophisticated algorithms enable the inking of straight lines without jagged edges and curved lines that accurately follow the pen motion.
  • Hover Sensing – Adding a third dimension to the touch experience, the active pen can be detected as it is approaching the screen. This allows opening of menus to allow more choices before a selection is made. In addition, a landing point is projected as the pen approaches to enable accurate selection.
  • Pressure Sensing – The tip of the active pen contains a pressure sensor, which can detect 256 levels of pen pressure. For example, the line thickness can vary based on the pressure on the pen tip.


Penabled® Technology

Backed by a record of more than two million units shipped worldwide, Wacom’s pen tablet devices have proven enormously popular with users across the CG field and are firmly established as a de facto global standard. Our original EMR® (Electo-Magnetic Resonance) Technology is essentially the same as our traditional epoch-making core technology. Innovative and flexible, EMR not only provides «free pen experience» for the end user, it also opens up a huge range of possibilities while offering a number of distinct advantages to partner companies that build Wacom pen tablet devices into their products.

Wacom’s Reversing Ramped Field Capacitive (RRFC™) touch technology enables revolutionary performance in touchscreen applications. The technology can be integrated into dual-input applications with Wacom’s market-leading EMR pen-input technology for Tablet PC and other portable device OEMs, or work in other platforms that require only a finger touch interface.

Here we introduce the versatile features and advantages of Wacom’s original EMR Technology that other pen input systems just don’t have.
