After learning how it is used, will you say it is easy to know what ishappening in the device without looking at them when the hapticfeedback is turn on?Two of the participants point out, they feel they need to know more the systems tobe able to interact without looking at the screen. Also two regards the home screenis the easiest one to work without looking due to the little number of items. One of theparticipants says it is not easy to know what it is happening without looking. Thisparticipant is the one that did not manage to navigate along the screen, so theparticipant did not get any navigation feedback. That is why this participant point ofview is not regarding navigation feedback and will not be considered as a test of it.But it will be considered regarding personal opinions.Will you say that haptic feedback had helped you in this in theusage?Taking into consideration that this question is regarding navigation haptic feedback,participant two answer will not be considered.One participant out of three say it helped and another one say that it do not.The last one, points out that he feels quicker when he is not using the navigation inthe screen. So, he thinks he is not helped.In which task do you think haptic feedback has helped you most?The three participants that use navigation feedback said that the home screen is theone where haptic feedback helped them the most. The one that did not navigatesaid is the volume selector level. The reason may be that even if the participant doesnot navigate the volume selector level navigation feedback can be felt.Will you prefer in any task the option without haptic feedback? Inwhich one? Why?Half of the participants do not prefer any task without haptic feedback. The otherhalf rather scroll without haptic feedback.If this touch screen had been installed in your car and you are ableto turn off the haptic feedback will you do it?None of them say they will do it.Other comments:There are two participants who note that there were conditions where thenavigation feedback is not useful due to the tightness of the items. Also, the sameparticipants observe that there is a lack on other sense feedback. One of themmentioned that the use of a wider range on haptic feedback might be useful.Another one, that the haptic feedback is so low that ask so many attention from him.One special remark was that the radio dials shape is difficult to follow. Last, thatsome of them have problems using the volume bar. That might be caused by thesmall design of it.63
