where can I find a fine point stylus be purchased for the iPad
Capacitive touch screens to not work with fine point styluses. A certain amount of surface area is needed to make things work. The closest thing you are likely to find at this point are the Jot styluses (and a few similar solutions). They get mixed reviews, so YMMV.
There are a few Kickstarter.com projects that show promise. They combine infra red and/or bluetooth tech to enhance stylus performance. I don't think any of them are available yet, but you can sign up for one of the projects if want.
I am going to be interested in seeing if the new retina screen on the iPad 3 will allow finer point styluses to be used.....
Unlikely. The sensing part of the screen has nothing to do with the display resolution.
I understand that there is a mathematical algorithm that averages activated points on the screen and computes the centroid, but I assume that the precision ultimately depends on the screen resolution. If so, then they could tweak the algorithm to provide better pointing precision.
I guess time will tell----.
No. The layer of the screen that senses your finger has nothing, nothing to do with the layer of the screen that provides the display. One senses capacitance on a grid of sensors. The other emits a grid of light.
It is possible Apple will increase the sensitivity of touch, but they do not need to change the sensing grid's resolution in order to increase the display's resolution; nor vice-versa.
This came out for the iPad 1. However nothing came of it, apple does not allow this in the app store because it used private API's and there is not way to do this without using the private API's.
Its, possible, just not allowed.
Interesting. I kind of remember seeing this, but had forgotten all about it.
I suspect that the demo would not have worked as well if they had used someone else's stylus. That kind of tweaking of detection has got to be pretty finicky.
Yeah, but one would think that if Apple decided to go to a higher resolution image capability they would also provide a higher resolution touch sensor grid. Otherwise there could very well be an issue with trying to track something on the screen that required more pointing accuracy than the system could deliver.
In any event, it would be sort of poor judgement not to---.
Boy...I only wish. I'd love to have a nicely balanced, weighted fine point stylus. That would be the cat's pyjamas.
