Transform a Regular LCD Into a Touchscreen

eZtaR writes "NAVisis is introducing a new USB gadget (for Windows only including Vista) called LaptopTablet. You mount it onto the side of your regular LCD monitor to transform it into a fully functional touchscreen, controlled with an included pen. The gadget is priced at around $100 and seems a good alternative for Photoshoppers."

    Unfortunatly, I don't think this will be much more than a neat gadget, and it certainly won't live up to the needs of a serious artist. There's no mention of accuracy or pressure sensitivity, and I didn't see art/photoshop listed on the website. I'd be keen on seeing some reviews of it, and the prospect of attaching it to a laptop screen sounds pretty interesting but for the price I'd rather just pick up a small Wacom tablet. The fact it's made mainly for a laptop monitor only and claims to work only for Windows makes it a pass for me.

      His "borderline troll" is undoubtedly accurate.

      Pressure sensitivity is key for most any artist, it's where the real value of the Wacom tablets lie, allowing you to control the quality of your brush strokes with pressure as you work. That's a bigger part of the tablet's advantage over the mouse than the actual "pen" method of input for many artists. This makes no mention of any kind of pressure sensitivity. Clearly, it can't make the screen pressure sensitive. Perhaps they could build a sensor into the pen that measures pressure and use the edge device for position, but that doesn't look like it's what they did, their pen looks like a "dumb" device, not a wireless pressure sensor. Even if it did have a pressure sensor in the tip, it's going to have to be so sensitive that it requires a really light touch, or else you're going to mar your screen, and that would greatly diminish its value.

      As far as resolution is concerned: they say "sampling" is at "about" 400 DPI (whatever that means), but then it says "recognized resolution 0.2mm" which is about 125 dpi. The Wacom tablets artists work with recognize a resolution of about 5,000 lines per inch.

      I'm sure you can draw a cartoony sketch with it just fine, but there's no way this device as it stands now is going to replace tablets for professional artists. That doesn't mean it's worthless. A lot of thing you want to do with touch sensitive displays isn't professional art. These could be a much cheaper alternative for touch-sensitive user interfaces and games and such. Maybe in future generations they will add some sort of pressure sensitivity through the pen and increase the resolution by an order of magnitude. Until then, the "borderline troll" is correct.

      "sounds like you think conventional graphics pads/tablet PCs have squidgy pressure sensitive screens?"

      No, I did not think that. As other people have posted before in this discussion (at +5), "conventional graphics pads/tablet PCs" have screens that are tough and scratch resistant and are designed to be pushed on all day with the tip of a stylus. This would destroy conventional LCD's. So, as I said in my post:
      1. It doesn't appear that this device has any pressure sensitivity, and
      2. If they wanted to add it, it would have to use really light strokes to not damage the LCD, which still isn't very valuable.

      Maybe they can sell it with a thin polycarbonate screen protector or something, but I doubt that would fit in most notebooks and allow them to close. Perhaps it would be good for converting desktop LCD's to touch-screen though. Of course, they'd have to offer a huge variety of sizes and shapes of screen protectors. Or perhaps expect people to cut-to-size with a paper cutter or something. Anyway, I don't understand what there was in my post that made you think that I thought that the screens need to be sensitive to varying degrees of pressure; all I pointed out is that the stylus can't respond to firm pressure on conventional LCD's without damaging them.

    Who wants to hold their arm out, hovering over the keyboard, attempting to "draw" on a surface that isn't firm (laptop hinges are not designed to resist pushing on the screen)? This is a terrible idea in my opinion. The big advantage of *real* tablets is that they fold "roughly" flat so you can write/draw on them more naturally. Even at that, they are usually too thick, making writing uncomfortable.

    Most pros I know use a Wacom in Photoshop or Illustrator, but mostly they're mouse people.

      The reason they're mouse people more than tablet people is that most software sucks on a tablet -- many on the common UI elements that work well with a mouse fail completely on a tablet. You really have to design with pen based interaction in mind.

      I'm about as serious as they come in regards to Photoshop and completely disagree with you. I use a Cintiq (Wacom) daily which is a LCD screen controlled by a stylus. And sketching on screen with a stylus is unequivocally superior to sketching with a mouse (and on a separate tablet IMHO). It is simply natural to look at what your drawing.

      In regards to TFA, pressure sensitivity is the key aspect in art/design applications. I saw resolution mentioned, but nothing on pressure sensitivity. If this device has no, or little pressure sensitivity it will certainly remain a non-artisan tool for the majority of users. Personally, I would not be interested in this product because most laptop screens are 'soft' and susceptible to damage, and the keyboard is in the way.

      Oh, right. I was just thinking of my own retired flat CRT. I've cursed the name of the sometimes ball-formed CRTs ever since I got the flat one, years ago. So much easier on the eyes, so much better accuracy. Funny thing is the old 17" Viewsonic (G73fm) of mine still compares rather well with today's CRTs.

      The product page however still says that you can use the gadget with any flat surface, but I don't have the heart to tell more of my fellow Slashdotters to RTFA. There's no need to ruin your LCD.

      One thing for artists to consider is however that you can probably opt for a any textured surface to give you any amount of "pen drag" you wish. All the tablets I've tried so far are very slippery, which is by no means always a good thing. I could pick a rough paper, or even a textile according to what I feel is comfortable.

    I support a salesforce of about 200 who use various touchscreen PCs from HP Ipaq to Fujitsu tablets and laptops. at first they were ecstatic about the touchscreens then they slowly figured out that it was actually quicker for them to use the mouse/keyboard instead of having to touch the screen x/y on this side of this form and -x/y on this side of another button, etc in order to put in their orders.
    the screen doesnt go out of calibration uniformly across the whole screen, but generally in 5 different ways in the 4 corners and in the middle. this is a nightmare to use and to support!
