title: UX Design for Disabled Controls w/ the Touch Interface
body: <p>So we're re-designing a desktop application so that it's also usable with thye Touch Interface with Windows 7. We've consulted the UX guidelines.</p>
  
  <p>For some part of the UI, there are toolbox icons that are disabled because of some arcane rules (the software communicates with a hardware device). We disable the actions that aren't applicable (because of some condition) and let the user hover the mouse on the tool icon to see the tooltip explanation on why that tool is disabled.</p>
  
  <p>Since there is no "hover" for the touch interface (windows 7, iphone, ..) what is a better pattern/model for this?</p>
  
  <p>Thanks!</p>
