3.3 First prototypeAfter all the research has been done and all the requirements regarding touchscreens have been enumerated, the desired preferences in relation to touch screentechnologies for haptic feedback has been listed in desirability order (table 3.2).The first choice was the surface texture changing; this product was indevelopment by two companies Senseg, a finnish company creating E-Sense(Senseg), and TeslaTouch, a division in Disney Research Headquarters in Pittsburgh(Disney). Before including this technology as first choice in the list, it was necessary toassure that this technology is available for development. No answer was receivedfrom TeslaTouch and Senseg informed that the technology is not mature enough tobe able to give support to the developers. That is the reason why this technologycould not be used even if it was the most suitable one for the purpose of this project.The second choice was the localized screen vibration technology it has thesame good qualities as the first choice but with one main drawback, being theaddition of vibrations to the car environment, even if these are minimized comparedto other vibrates technologies. But the problem was the same; there was no devicein the market including the necessary features to enhance the localized feedback.There are just patents related to this technology.Due to this unexpected fact, a backup solution must be found. It was then thatit was decided to try to reproduce the same feedback that was supposed to becreated in the first two choices with a less advanced technique.The next best option among the haptic feedback technologies was the screentactile display.This list has been submitted to the approval of Volvo Cars when consideringtime and economical issues. They evaluated each of them and decided to buy atechnology including android technology, the Galaxy Tab from Samsung (figure 3.2).Figure 3.2 Picture of a Galaxy Tab31
