Thread: iPhone Stylus
10-01-2007, 10:15 AM #1iPhone Stylus
I am curious if anyone has found a stylus, or something similar, that works with the iPhone. I have no problem myself using the touchscreen interface but my mother tried to use it the other day and her fingernails got in the way. When she tried to use her fingernail to navigate through the phone it didnt work at all. Im pretty sure its because the iphone interface uses static electricity from ones finger to recognize that it is a person and not your keys or something else in your pocket. Currently she uses a palm pilot as her pda but I would like to get her an iPhone, any suggestions?

Curious myself about this since I used a PPC for many years and never used a stylus like most ppl do I only used my nails as my stylus but this is not an option on the iphone and now my nails get in the way when I try to use my fingertips. (extremely difficult to use when you have long nails)

I believe the touchscreen uses technology like that of the touchpads that Apple uses.
"A conductive surface (such as a finger) is needed to move the cursor. Pointing devices such as pens, a Newton stylus or even a finger nail won't work...."

I believe someone has produced a silicon rubber stylus that duplicates the skin conductivity. I find the "keys" on the iphone would benefit from something smaller than a fingertip.

if you could heat up a stylus to about 75-100 degress it should work...remeber the iphone is heat sensitive...thats why it dosent work in your pocket.

The touchscreen technology on iphone is FTIR, or Frustrated Total Internal Refraction. It uses neither heat, nor conductivity, but refraction of light. Not sure what the rules are on embedding URLs but here's some video on it:
an amateur video of homemade FTIR and raw data:
jeff han (the guy who came up with its applicable use) and some neat-o stuff he's working on with the same technology:
As you can deduce from the raw data video, fingernails don't provide enough surface area to register a 'touch'. My suggestion: knuckle, maybe? or stick a cork on her fingertip
edit: actually that tapright thing looks good.

its not refraction of light... that's only for the larger multi touch.. apple iphone uses an fine mesh under the glass that picks up electrical disturbances

I like the touch screen and find it very easy to use and to type with both hands
