Summary:

  • easy-to-use data/keyboard entry interface
    • big buttons
    • audio clicking feedback
    • fast response
  • always able to back up or quit transaction
  • the dialogue provides a personal touch

Planned user experience:

The first screen gives three options to select. Examples of tasks that the APC can do are purchasing stamps, calculating and printing postages, weighing packages and looking up information. This is done with the touch-screen interface. There is a physical keypad and wheelchair accessible navigation panel (pictures in the "observe" section). Payment is through credit or debit card and stamps and or receipts are printed. Unless there are problems, this is done without the help of any person.

In this first video, I attempt to mail my notebook to a zip code which I don't know. I enter the city's name in order to find the correct zipcode. Listen for the audio feedback as each on-screen button is pressed. Click here if youtube doesn't work.

In this second video, I want to print out information about postage for a zip code. With one hand with the camera, the other hand is still able to enter information quickly, even with mistakes. Click here if youtube doesn't work.

The following pictures highlight other aspects of the experience.

  • easy to press large buttons
  • confirmation, in case information is incorrectly enter
  • asking to type first four letters only reduces number of keystrokes needed
  • APC spots the omitted space and asks if I meant something else
  • on the bottom corners, there is always an option to back up a step or exit the transaction
  • the picture explains the orientation necessary to insert the credit card
  • yes, it is just a machine, but saying "I'm printing your receipt" makes it sound more personal
  • APC also tries to relieve the hurried customer
  • while someone in a rush might not notice the personal dialogue, I felt that this added to my experience
