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."

  1. Aren't normal LCDs a bit fragile for this? by WillAdams · · Score: 5, Informative

    The touch screens and active stylus input displays have a thick glass or plexiglass or other durable substance to protect the screen, but every LCD (laptop or desktop) I've ever set up has a warning about not touching the screen in w/ the setup / operating instructions.

    My boss and several co-workers regularly touch the LCDs here in the office, making the surface bend and distorting the image and it makes me wince everytime.

    Needs a pen, that sucks. I prefer real touchscreens where you simply touch them like the ELO.
    as for photoshoppers, doodling on a monitor sucks. Using a pen tablet on the desk is far easier and way more intuitive as well as not having your hand and pen device in the way blocking your view.

    This is a neat device, but for the price you can get kits from ebay to add a real touchscreen layer to your lcd or laptop instead of something that requires a special pen.

  3. Photoshoppers ? by fruey · · Score: 3, Informative

    A serious graphic artist probably wants a CRT for accurate colour, gamma, etc. And at least an A4 Wacom if they prefer drawing, but on a horizontal rather than vertical surface.

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

    I can't imagine that a serious Photoshopper would want to use an LCD screen and draw on it with a stylus, it's just not accurate enough.

      Look at a wacom cintiq -- they're really nice.

      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.

      Look at Alias SketchBook for an example of a UI that works well on tablets

    There's no mention of accuracy or pressure sensitivity, and I didn't see art/photoshop listed on the website.

    Says 400 DPI on the page linked to and go check the "Example" tab for art. It's good enough for anime.


    Really, Read The Fucking Article/Product Page/Whatever next time. Borderline trolling, what you posted.

    So what you are saying is that they don't work right so people don't like them, even though they find the idea very attractive? Most technology doesn't really catch on until it actually works right, so I'm not sure why you are surprised.

    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.

  11. NAVisis is not really new with this technology by Codacas · · Score: 2, Informative

    I have a business and have implemented the use of a S/W program that is heavily based on touchscreen technology for production. The funny thing is that I have gone through 2 of these expensive suckers (CRT & LCD) before getting smart. I now buy cheap lcd's and cheap overlays!! The cost is almost a third of the price of the complete unit and work great. But here's the real funny thing, I always, always always, always check a technology company's bottom line of their web site for their copyright date to see how good they are keeping the public web stuff current. NAVisis's web site has a copyright of 2002. :-o This technology is not new stuff anyway they are just catching up.
