Transform a Regular LCD Into a Touchscreen 146

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."

        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.
        • Not to mention that the Intuos3 series is capable of sensing pen rotation and x/y tilt.

              Considering that a Wacom Cintiq is well over two grand (for a 21" LCD), for that particular market such effort would be worth it -- $300 + $100 + a little work is a Hell of a lot better than $2500!

    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.

        For all laptops that I've ever seen (except tablets) 1) folding the screen backwards so that it's parallel to the desk (if it can go parallel to the desk..

      Let's just accept that "photoshop" now means raster image editing. I use Linux exclusively for many, but when I manipulate an image with GIMP I still say I "photoshop" it.
  • Am I the only one thinking...

    cool, I'll just spend an extra $100 on a 17" or 19" LCD monitor and lie it flat on the desk. I'll drive it with the second monitor output of my graphics card. For screen protection I'll buy some kind of 3M film from staples for $10 a roll or a 200 pack of laser printable transparency sheets.

    or even - I could roll my own context sensitive touch tablet, instead of a $1500 OLED keyboard

    I think you meant to say "graphics professionals who use the software application Adobe Photoshop®."

  • Well, im reading that and thinking wow, that is interesting.

    Until I get to: The gadget is priced at around $100 and seems a good alternative for Photoshoppers.

    Im not much of a phtotoshopper, but what unmet need does this meet for photoshoppers?

    • A tablet is superior to a mouse for just about any photoediting purpose, and most drawing purposes. So yeah, it's an alternative. However, most of the value of having a tablet is its pressure sensitivity, which this device does not have. So I wouldn't say it's a 'good' alternative to a real tablet.
  • Looking at the technology of this device, it does not monitor touch, but instead the position of the pen. A "real" touchscreen does not require a special pen to register a touch, your finger is typically used. There are many types of touchscreens, some actually respond to the force of your touch (resistive technology), some sense the capacitance of your finger, others the acoustic damping caused by your touch, and a new technoloty even "listens" to the sound of your touch and calculates where you touched.
  • 1. is it 'ultra' enough to be completely inaudible? I've had some experience with ultrasonic devices for cleaning etc. and they are unbearable to be around due to the high-pitched shriek they emit. To be fair, this is at much higher power levels than this pen will use.

    2. Ultrasonics can be quite destructive, both on the laptop screen and on the bones in your hand (again, more of a problem at high power levels).
  • "Enjoyable ink chatting on MSN Messenger."
  • It's not a touch screen, it's a Light Pen [], straight outta 1957. Everything old is new again...
    • No, it is not. This and a lightpen use completely different technologies and position detection systems.

    In the same way that a cut finger is an alternative to a pencil.

    Actual art tablets that are specifically designed to use with Photoshop (and vice versa) start at $99.
  • There seem to be a lot of comments saying that this device is useless to artists because of lack of resolution and pressure sensitivity. True, but it misses the point. I used to use a Psion 7, a lovely little A5 size clamshell machine running a proprietary OS. It was ideal for taking notes in meetings as I could go straight from touch-typing to sketching a diagram straight into the word processor. These days I use MS OneNote, which is slightly more clumsy in that respect (much better in other ways). If I ha
  • 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
