There are limits to how much you can understand users' interaction with your mobile app or site if you just stick to pixels, and never leave your computer screen. You need to get designs on the device, and check if text, buttons and icons are visible, and safely clickable.
The only way to do this on every platform, is measuring with some sort of real life, physical object. Instead of muddling through with other tools, I made a tool specifically for doing this on mobile devices:
I'm currently in the process of developing a touch based interface
for AV system control. When deployed, the interface will be operating
on proprietry touch input hardware however I'm looking into
technologies I can utilize during the development and user testing
Users involved in the testing are geographically distributed so I'm
looking for tools I can use to quickly push out interface concepts
I'm just itching for haptic feedback. I read about mobile-phone screens that
have the capacity to simulate a clicking feel, so a flat screen pushes back
to mimic what your finger would feel if there were a mechanical button to
I'd like that, but on a much larger scale. I want something the size of a
desk that lets me drag objects between the flat and the upright part of my
workstation, and lets me feel the edges of things as I push them across my
desktop with my fingers.
So, specializing in web apps, I've had precious little work on
touch-screens (especially for mobile platforms) come across my desk.
However, the market seems to be heating up.
Although many of our skills are easily transferable from one platform to
another, I personally could use some reading on the nuances and
strategies associated with good IxD in relation to mobile and touch
Do any of my fine colleagues out there have any links to how-to-guides,
studies, and interaction overviews related to mobile platforms and touch
