This is something about the fear-factor in people, restricting them to be over-cautious and prevents them from proceeding further.
The Router problemThis morning I took my broadband router to my area service provider's office. Recently the router was behaving erratic and I was asked by the customer support executive to get it exchanged at their office, nearest to my place.
Update FirmwareAfter checking the Router, the officer suggested me that flashing the firmware should fix the issue. Then he connected the router to his computer and accessed the router's control panel. By this time he dialled another engineer who was instructing him on how to flash the Router. This officer started reading out the links displayed in the monitor and the engineer on the other side instructed him to click relevant links. I understood that the officer is new to this and without the engineer, he is of no use.
The User InterfaceThe modem's Firmware update UI displayed a simple screen filled with instructions grouped in a step-by-step manner. So Step 1 instructed the user about how a flashing is done, how long it might take etc. At Step 4, there was a file selection textbox with "Browse" button, and a "Update Firmware" button displayed below. The officer promptly clicked the Browse button and selected the Firmware file from his Windows Desktop. He explained his actions to the engineer over the phone and it seems the Engineer couldnt remember what to do next, or he doesnt remember whether a Button is displayed or link is displayed etc.
Instead of clicking the "Update Firmware" button, the officer was reading out all the instructions and the clueless engineer was unable to help him over the phone. To make it worse, the officer did the entire process once again. I was watching all this and when I suggested him to click the "Update Firmware" button he was hesistant to do so. I quickly understood that the officer had the classic "fear factor" which prevents people from doing a new thing. And looking at the User interface I could clearly see what the problem is and how to fix the issue.
Problem:The page heading and the button had the same text "Update Firmware". And, lack of clear instructions. So the officer had assumed the "Update Firmware" button to be a - heading displayed in a rectangle box redundantly in the bottom of the UI. So he had ignored the button and told the engineer that he is seeing "Update Firmware" everywhere. And the engineer was clueless then.
Solution:Introducing a Step 5 saying "Now click the button below to start Firmware update" and showing the "Update Firmware" button there would have solved the issue.
Observations & Conclusion:People generally refrain from clicking buttons or exploring or even reading contents that are new to them, or not familiar to them. It is the fear-factor, "what if I click the wrong button, or my action produces unwanted results?". This is a challenge in User Interface design. Wizard or Step-by-Step approaches should cover till the final action to be done. Just because of a simple instruction left out, the whole user experience had become terrible.
A good user friendly User Interface should hide that fear factor and must encourage the user to engage with it. It should also provide an option to roll-back any changes made. Only by creating such "cushion" feeling, a user-interface can make people to use it without any fear.
