Extreme handwriting recognition on the Dell Latitude XT2

Dell Latitude XT 4by3 This is my first and possibly only handwritten blog entry…

that’s because ‘an in a cramped airplane._ seat and the ride is d little bumpy. that, and everyone who can see what lam dough watching me avidly’ The XT2 uses windows7 pen extensions and as a long ten fan of the concept of pen computing I touchscreens and the business of handwriting instead of keyboarding.

the windows7 pen or touch keyboard relies heavily on dictionary prediction to figure out peoples scribbles and this brings some odd problems with it-such as entering passwords: whether it guesses right or not the handwriting paid will briefly display your password not just in plain text but clearly legible plain text at that

And now I’m sitting somewhere that isn’t moving at 450mph, I can finish this on the keyboard. The first thing that springs to mind is how the Dell Latitude XT2 compares with my ancient Fujitsu tablet PC: I was interested to see just how well a new device, powered by Windows 7, would cope in what is effectively a torture test. I admit it’s entirely unfair to expect any machine to recognise text perfectly in that situation, so all told I’d say it did pretty well.

Another obvious difference is that far less “training time” is needed to get good results: this may be because the touchscreen is much higher resolution and seems well adapted to the level of pressure and speed of movement I have developed as a 20-year fountain pen user. Also unlike my old Fujitsu, the Dell will use either the smart pen or your grubby digit: the finger works only on contact, the pen works a couple of centimetre off the surface.

The XT2 also makes a nicer regular laptop than my trusty Fujitsu 5020. This is mainly because the screen technology doesn’t add as much blur to the display as it did on the Fujitsu.

Windows 7 makes a number of subtle but smart differences to the experience, too. I find it much more natural to tap the bigger Windows 7 icons on the touchscreen than I did the various menus and controls in Windows XP, and that’s faster than noodling about with either the trackpad or the keyboard nipple.

Sadly, Dell can’t resist layering its bloatware “location manager” over the top of Windows 7’s wireless/wired network connection management; having used the default Windows 7 stack on a ThinkPad T60, I don’t really see the added benefit of most of these manufacturer-specific add-ons.

I like tablet PCs as a concept, because I like to handwrite and I need a compact device when I’m wriggling into tight corners behind server racks. I have seen one very serious application in an orthodontic surgery which relies on tablet PCs as a core part of what it does, and I have no doubt this will be a growing field.

But if I send in any more blogs spelled and punctuated like the first couple of paragraphs here, PC Pro’s online editor will stop talking to me altogether.

    I’ve used an IBM/Lenovo X60t Tablet for a couple of years now, and have rarely found that the handwriting facility offers any real advantages compared to a keyboard. However, the touch screen itself is definitely useful, even if it is for the odd “stab” at icons on the screen – something which you get surprisingly used to (the number of times I prod the screen on someone else’s computer!) Additionally, the ability to quickly annotate and take notes is very useful, as well as for controlling PowerPoint etc.

    I don’t think it will become a proper replacement for the keyboard (which all things considered, works very well), but I think I would miss it more than I realise.

    I love the X series IBMs but my suspicion is that there’s a new wave of touch screen devices this year. Having said that, Win 7 downloaded a firmware update for the multitouch controller on the Latitude and itäs been misbehaving oddly ever since…

    It will be interesting to see what does come out – I can definitely see the benefit of having touchsrcreen as a navigation aid, especially with the development of eBooks / dual technology screens. I took the plunged an rigged up the home computer to a 52″ touchscreen, and that is great fun to use with Media Centre and Windows 7. However, as you mentioned in the post Steve, the input still lacks the precise ability to be truly useful as in input at the moment.

    I’ve also had a sweet spot for the X series, starting with an X31. Absolutely superb laptops, although I have noticed a slight drop in quality with the X60t (not a problem due to the excellent warranty)!

    I’ve been holding off buying a new refresh of desktops and laptops for my work to wait for new models more suited for W7 but with 31st March looming soon I’m going to have nite soon.

    Unfortunately HP (my preferred manf.) still have a lot of their laptops on their website with Vista loaded which I find astonishing. I bet once the new financial year starts the new models etc will all start coming out.

    Come on HP, get your finger out!

    I’ve been using an XT for a year now & I find that I can’t live without a tablet. However, I rarely use the handwriting recognition. I find that MS OneNote is an excellent resource for recording notes & scribbles through all of my meetings. The XT has not only greatly diminished the amount of paper in my life, now that all of my notes are in one place, I can ignore them much more efficiently than ever before.

    I’m with Matt, after using OneNote since it’s inception, I find it’s by far the most useful application I have on my notebook. The 2010 version is even better, just a pity it wasn’t a part of W-7, rather than having to buy it!

    I grabbed a few demos from http://www.paragraph.com (aka http://www.phatware.com) – it pays to look around off the beaten track when it comes to tablet apps.
