N-Trig makes the DuoSense technology that powers the Dell Latitude XT's touch-sensitive and pen-enabled display. This is the only input device in the market that combines a pressure-sensitive pen with multitouch into a single surface, which allows for seamless iPhone-style finger interaction—perfect for broad, direct object manipulations—and precise stylus for electronic ink input and drawing. The good news (specially for Apple tablet-obsessed people) is that Dell is only the first of many leading manufacturers looking to use" their technology, according to Abigail Solomon, N-Trig's Director of Marketing:
Jesus Diaz: Are you working with other big brands on this? And I mean BIG (wink wink nudge nudge.)
Abigail Solomon: Yes, N-trig is in discussions with other leading brands, but we are not in a position to discuss who.
JD: What kind of companies?
AS: Well, not only notebook makers. N-trig's technology is not limited just to notebook PCs. Think gaming, handhelds, medical devices, TVs, computer screens... anything with a screen.
JD: How does this technology compare to Wacom's pressure sensitive displays, which seems like the current leader? I know theirs is not capacitive touch, but I thought their pen technology was unmatched.
AS: N-trig's sensor materials are combined with sophisticated software algorithms which enable true digital touch and can be easily be integrated and supports any type of LCD or size.
JD: But does your pen require a battery?
AS: The pen is an electrostatic pen, so no, it doesn't require battery: the stylus is light ergonomic and customizable and requires no internal power source. It has an integral sensor that changes transmission frequency in accordance with tip pressure, which has a more natural, hassle-free, and life-like pen experience. It also features right-click and eraser capabilities.
JD: How many pressure levels does it support?
AS: It currently supports 256 pressure levels [By comparison, Wacom display technology supports 1,024 levels, plus tilting and bearing, but no finger touch. JD], since it is the standard for mobile computing devices. For other types of devices we may enable more pressure levels, as it may be required by each device standard.
JD: Does it support tilting and bearing like the Wacoms?
AS: No, the pen does not support tilting and bearing since it isn't required by the operating system. However, in terms of touch performance DuoSense introduces outstanding accuracy and full compatibility with Microsoft Vista requirements and features.
JD: How does the dual input work, having to cope with the hand touching the surface while using the pen?
AS: We have a feature called intelligent digital palm rejection, which enables the user to switch seamlessly between the pen and the touch functionality. The DuoSense displays knows when you are using the pen or expecting it to react to your finger input.
JD: Amazing stuff. Thanks Abi!
AS: Thank you!
So as you can see, this technology is completely new and totally different from what current tablet manufacturers have in the market now. So new in fact that when we first talked with N-Trig back in October, they were still in the process of ramping up manufacturing and couldn't even discuss the technology in detail. The Israeli company, which has offices in Tel-Aviv, Taiwan and Austin, had Dell lined up at the time, as well as other undisclosed OEMs.
The ability to have electrostastic, battery-less pen input with 256 levels of pressure and being able to seamlessly exchange from pen to hand to pen without a single hitch is quite unique; to the point of justifying the price difference with regular pen-based devices.
More importantly, it feels natural and simple. That simplicity is what got me thinking that, if the rumors and patents hold any water, a company like Apple would not have any other choice but to use DuoSense (or something equivalent to it, if it exists.) It's one of those things that Steve Jobs would set as a requirement for any portable with multi-touch and ink capability, the latter already supported in Mac OS X.
However, right now the only game in town is Dell, even while their Latitude XT doesn't have multitouch support. There has been some speculation about why the Dell doesn't support multitouch at this poing, with some people blaming Vista for the lack of multi-touch. While it's true that future multitouch support in Vista will make things easier—thanks to system-wide programming interfaces—for any program to support the capabilities of the DuoSense, "Vista is not the issue," says the company. According to N-Trig, "all it takes is a firmware upgrade and it's ready to go," like the pressure levels. Why not putting it in, then? N-Traig pointed that "this is all we are allowed to say at this time," which makes us speculate that it was an strategical decision due to the lack of multitouch-enabled apps. And that all this secrecy must have a very good reason.
We will have to wait and see who's the next in adopting DuoSense. Until then, here's a great demo to drool over:

Synaptics, the driver provider for the majority of laptops with trackpads, is rolling out an upgrade that allows for two new types of finger movement and application control. Similar to MacBooks, the Synaptics upgrade lets touchpad users flick two fingers across their pads to scroll through items or change modes. More intriguing is the "ChiralTouch," which detects circular trackpad movement and converts it into scrolling or rotation. Synaptics says that more than 100 apps currently support the new motions, with more to come. To get in on the new scrolling, check with your laptop manufacturers' support site (or Windows Update) to see if an updated driver for your model is available. 
Apple's 
Language translation service Google Translate has added the ability to automatically detect the source language, streamlining translations when you don't recognize the language. When you stumble onto a foreign language web site, the most difficult part of using sites like Google Translate is that you often don't know what the source language is. Google Translate's new Detect Language feature removes this limitation altogether, so translations are quicker and easier. Apart from the new auto-detection, Google Translate has also added support for nine new languages, and can translate from any one of them to any other. Not bad.
Mac OS X only: Free FTP application Cyberduck's 3.0 beta release adds gobs of impressive new functionality to the already excellent client, including Leopard-only features like Quick Look. Other new features include Amazon S3 and WebDAV support, Web URL support (which opens files in your browser from a corresponding URL), and the handful of already impressive features like integration with external text editors. Cyberduck continues to add innovative features that make it a viable contender to even the most popular shareware FTP clients, like
