The Vanilla Sketch. Today we had to provide two additional features which are made possible since we created the touch interface yesterday. This two features are illustrated above.  First of all, it will be possible to implement a timer - which will enable the oven to automatically turn off after a certain predetermined period of time. The oven could beep when turning off so the user would be informed that the dish // the cake is finished :) The other features is something concerning security. As children often turn on  the hot plates when they are tall enough because they think it's a kind of toy - the touchscreen would enable to implement a certain security mechanism which would involve entering a PIN-code in order to be able to turn on the stove. (For turning the stove off should be made possible also without PIN-Code because in emergency this is an important feature). I tried to illustrate those features above, using drawings annotations, notes and arrows :)

The Vanilla Sketch. Today's task was to take an existing manual for kitchenware and develop a touchscreen interface for that. I went for the stove because I often unintentionally turn on the switch for the wrong hot plate, because for me the switches are not positioned intuitively. On the top of my sketch one can see the switches as there are now - 2 for the oven and four for the stove. For my new touch interface I provided two sketches. The first one is for the use of the stove. There are four circles for each hot plate one. They are ordered intuitively in order to be able to get a right conceptual model. In order to turn on a hot plate one has to touch the appropriate hot plate on the interface and then position the scrollbar on the right according to the desired temperature. In order to enable the extended parts of a hot plate one simply has to touch the respective parts on the touch interface. The second screen shows the interface for the oven. There are only two parameters one can choose from - namely the name of the programm and the degrees. When clicking on either one, a combobox appears where one can choose from the programs or the temperature. I really tried to integrate the elements proposed in pages 91-94 of the Book "Sketching User Experience" which are drawing, annotations, arrows and notes. I think it's very important to add annotations and notes to one's drawings as they really improve the understanding of a drawing if someone is not familiar with a certain topic. I tried to use different colors in order to be able to differantiate between drawing and annotation. Especially arrows are an important tool - I will use them more often in the future to emphasize important points of my drawings :)
