Here are instructions for building your own mobile device testing device. It’s home grown, affordable but most of all it works beautifully. It is portable, light and easy to utilize for mobile-specific testing of mobile interaction.
gotomobile’s mobile cam provides a highly adaptable and easy to use platform to for imaging mobile devices during testing. It allows you to view and record the keypad and screen from the user’s perspective during a usability or other interface test – practically impossible in person without rubbing cheeks with the user!.
The goto cam device is small, easy to use, quick to setup and highly adaptable to different mobile devices. It is also easily adaptable to screen sharing and other usability testing packages such as Morae from Techsmith.
