Multi-Touch on Resistive Screens

Filed under Gadgets


Touch-screen phones existed well before the iPhone. The iPhone is different because it supports multi-touch. The iPhone uses a capacitance screen instead of the traditional resistive screen.

I assumed that a capacitance screen was a requirement to get multi-touch…until I watched this video.

Stantum is demonstrating a way to do multi-touch with resistive screens.

Advantages of resistive multi-touch screens over capacitance screens:

  • Cheaper
  • Works with *any* input: finger, fingernails, gloves, stylus, paint brush, etc.

This tech is a game changer…stay tuned.
