10 Hardware <strong>an</strong>d characteristics <strong>of</strong> the MUTE prototype 106<br />
controlled in order allow more fuel saving recirculation. A list <strong>of</strong> all available in- <strong>an</strong>d<br />
outputs is found in Appendix B.<br />
10.6 The user interface<br />
The user interface will be realised on <strong>an</strong> Apple iPad 2. The control signals are sent over<br />
a wireless network <strong>an</strong>d a car-bus system to the controller. A proposal <strong>for</strong> the interface<br />
with the options defined in Section 8.4 c<strong>an</strong> be seen in Figure 10.8.<br />

Figure 10.8: A proposal <strong>for</strong> the user interface.<br />
In the m<strong>an</strong>ual mode all the outputs (heater, f<strong>an</strong>, air distribution) c<strong>an</strong> be directly<br />
controlled giving a maximum <strong>of</strong> control to the user. Only the air recirculation control was<br />
<strong>for</strong> simplicity reduced to the common “yes or no” button. The goal in automatic mode is<br />
to have only the necessary options in order to distract as little as possible. Consequently,<br />
as the MUTE has no me<strong>an</strong>s <strong>of</strong> dehumidification, the humidity adaption is not available<br />
(the objective still is implemented). The air speed objective is not available as no direct<br />
air flow towards the passenger exists. Only the temperature preference c<strong>an</strong> be set. The<br />
defrost mode is available in the automatic mode in order to <strong>for</strong>ce the control to bring<br />
warm air to the windscreen, <strong>for</strong> example if the fogging detection fails.<br />
In addition, the precondition mode is realised, used to create a com<strong>for</strong>table climate<br />
in the car be<strong>for</strong>e the passenger starts driving. It c<strong>an</strong> be activated by a signal coming from
