Touch 3d Stylus

[Kansas Eiffel]

Ihave the same model you have and I am also having the same issue. I can't seem to find a stylus that will work with this thing. I wouldn't waste your time on the Dell Active Stylus. I just received my replacement stylus today thinking they sent me a defective pen. Turns out they just don't make products that work with their own products! I purchased this stylus because one of their knowledgeable reps told me it would work. Turns out they didn't know anything.

Yeah, I'm very disappointed in Dell, and in the fact that they are not addressing this issue. The active stylus is clearly not the solution, as this model was not made to be used with an active stylus, but I've seen on multiple forums that that's all Dell reps will tell customers. This is very frustrating given that part of the motivation behind the purchase of this model was the touch screen capabilities, which would allow me to take the notes I need for my job without having stacks of paper everywhere.

Just an FYI for all. The training documentation specifically states, "When a finger touches the screen". It makes no mention of a stylus.

The Inspiron 11 3147 is offered with a capacitive touch screen. Capacitive Touch Screens are an all-glass touch screen with a transparent metallic conductive coating. An electrode pattern printed along the edges which distributes a low voltage field over the conductive layer. When a finger touches the screen and draws a minute amount of current to the point of contact, creating a voltage drop. The current flow from each corner is proportional to the distance to the touch point. The X/Y location of the point of contact is calculated by the controller and transmitted to the computer.

Thank you for your reply. I only wish you had replied when I originally asked the question over a month ago, as it would have been more useful at that time. Indeed, one of my complaints in this thread was precisely Dell's unresponsiveness on the issue (and subsequent erroneous recommendation that its customers purchase an active stylus for use with this model). Perhaps Dell customer service should acquaint itself with the training documentation to which you referred.

In any event, it is not unreasonable to expect that a stylus would work on a capacitive touch screen, provided the stylus is made from conductive material (as most are). In fact, most touch screen devices do work with a stylus. This is why I originally posed the question. In this case, training documentation or not, Dell is the clear outlier. I'll be sure to read training documentations first if I ever consider purchasing another Dell product.

IOGEAR's Touch Point Stylus is essential for your tablet, smartphone, iPad or any other capacitive touch device. Coming in a 3-pack, keep a stylus at the office, home, and with you on the go. The durable, compact design allows you to take and store wherever you like. The patented rubber surface at the point of the stylus is sensitive at any angle, providing amazing accuracy when sliding, drawing, double tapping, playing games and taking notes on your capacitive device. Soft like your finger, the rubber point will not scratch your screen, or leave finger smudge marks.

IOGEAR's Touch Point Stylus is designed for those who have difficulty composing text with the small on-screen keyboards integrated in most smartphones. Whether you live, or travel to cold climate areas, you no longer need to take off your gloves to access the various applications of your smartphone, tablet, or iPad. Keep a stylus in your winter coat!

It seems to me that devices (such as navigation systems) that use a stylus for touchscreen interaction have become out of of favor. Instead most new devices are intended (i. e. larger buttons etc.) to use a finger (sometimes combined with multitouch) on the touchscreen.

I'd like to know the reason why the stylus became out of favor for this interaction. Is the reason that Apple designed the iPhone to be used by finger multitouch and anybody copied this design? Or is the reason that styluses tend to get lost (but it should not be a problem to buy some auxiliary styluses if you have such a tendency)? Is using fingers instead of stylus just a temporary fashion or is there some deeper reason behind why the stylus became out of favor?

You can instantly see why styluses were used with devices like these: You had no choice! How would somebody possibly touch the UI-elements on this screen with a finger?UI-Design was more dependant on lists as we know them from PCs, than on Grid-Views and nice huge tiles. The touch-interface that came closest to this was the Desktop of Windows XP touch versions, and those were just to heavy to use on a serious basis.

Capacitive touchscreens as we know them today were either really expensive, heavy or extremely inaccurate, adding to the inaccuracy of fingers over styluses.It just wasn't practical to build them into small mobile devices.

As you said, a stylus was doomed to be lost. Replacements were of course not very expensive, given the passive nature of the stylus, but in the end it was always kind of a bummer and some people just resembled to stop using styluses at all, and tapped the screens with their fingernails.

And this was not the only reason. The Stylus is kind of an oddity: It was needed to use your device, but it doesn't really belong to it. A touchpad is built in, using it is direct interaction with the device. Same for keys, they belong to your device. The stylus is a tool. And most users don't use tools, they want their devices to "just work". And even though the other methods are more direct, they still are not as direct as using your finger to touch the screen.

And this is where Apple stepped their foot in the door and did exactly that. A device that just works and that closed the gap between the usability of a feature phone and the feature richness and connectivity of a PDA. Users loved it. Press loved it. Everyone loved its simplicity, something were PDAs were certainly NOT strong. They were feature packed machines for professionals, used by only those that really, really needed it. (And tech-nerds, of course.)

The iPhone was intuitive, and it was most importantly useable! It isn't hard to explain , and if you got the basic principle, it isn't hard to use, because the input is so direct and so optimized for your fingertips.

Suddenly, the PDA market broke down. Nobody bought those things with the sticks anymore, companies tried to copy the iPhone and its huge success, and the only one who stood strong was Blackberry, because they had mail backends that companies integrated into their systems for years.

In the end, it's the consumers "fault". They didn't demand any devices with styluses, they demanded more devices with one huge screen and not more than 7 buttons. And that's what they got: They voted with their wallets, and still do. Capacitive touch-pen replacements for people that wanted the Stylus back were made, and are useable.

Styluses solve the problem of using an interface designed around precise targeting of elements (e.g. designed for use with a mouse) without requiring substantial changes to the interface itself. In this way, the same interface can be marketed for use in traditional mouse-and-keyboard scenarios and in mobile/touch-screen applications. This is the model that traditional Windows Tablet PCs applied:

This concept was only really useful for three things: taking handwritten notes, drawing and portability. Unfortunately for the concept, powering a large-screen mobile device meant having an equally large battery, and so the units were never particularly easy to hold or carry. Add to that a distinct lack of purpose-built third-party software for the form-factor and most users not necessarily needing or wanting to take notes by hand or draw on their computers and the experiment failed.

The real innovation of touchscreen devices designed for use with a finger is the overhaul of the UI to put that form of interaction first. Using a tablet PC for anything other than sketching or annotating always felt like a compromise and that you'd be more productive with a mouse and keyboard. Using an iPad with a mouse-and-keyboard (as in the iOS Simulator Apple makes available for developers) is a real chore: the interface is designed from the very beginning to be used with a finger.

Add to that the ability for users who do wish to use a stylus to be able to do so (albeit with fairly crude accuracy, at least for now), and there are few users who are better supported by a stylus-first design model.

You can't operate a resistive touchscreen with your finger, at least not like a capacity touchscreen. Resistive touchscreens pretty much need hard objects in order to work correctly, which means your fingernail or a stylus. It won't work nicely with the flesh on your finger tip.

IIRC, stylus for capacitive touchscreens didn't even exist when capacitive touchscreens first came out [citation needed]. Most current styluses are not more accurate than finger tips, which makes them mostly redundant. Also because of this, the UI design has become adapted to using finger tips, so the need for high precision has greatly reduced. Also, styluses for capacitive touchscreens have special designs, which means more expensive than those for resistive touchscreens, which is simply a piece of plastic.

Do note that some current smartphones or tablet devices also provide a stylus. However, the stylus uses a different technology than the touchscreen itself. The touchscreen is still capacitive, which makes it the same as #2. On the other hand, the stylus uses a technology similar to that on drawing pads. The use of stylus is usually for taking hand notes or drawing, which requires high precision.
