When people using a PostureErgo’s prototype application .We will let the user trial prototype by themself to study the reaction of user to an application. Is the application is easy to work or it is too confuse to the user .We have to collect the complains from the user and analyze it.
As the purpose of the usability test is trying to design and develop the application in accordance with the actual needs of the user. If the user feel that an application is not easy to work or might be not convenient to use. We might have to develop it once again to develop the application to satisfied the user.
