Green Street Project – Kickoff

After nearly 2 years, I revived an idea of the “Green Street Project” which I described in my master thesis from 2011.

Here’s a brief introduction:

The Green Street Project should motivate drivers for a more economically driving through the awareness of the community’s driving behavior. To reach this goal, the driver will be notified via visual feedback, how people drive on this specific area of the street. Every driver contributes to the “green state” of the street through his/her driving behavior. In the first place, the “Green Street Project” does not target to educate the driver, but to motivate the driver to take action, which is in my opinion the very first step (and most effective) to change behavior.

My first attempt is to create a mobile application, which is connected to the car. Interpreting the car data via ODBII interface, my goal is to calculate an “eco value”, which is the contribution to the community’s behavior on the specific location on the street. So,… this will be a challenging part for the next weeks ;)

zapDial 2.0 – Nominated for the EUROPRIX Multimedia Awards 2010


You know the situation? You just want to quickly call a number from your address book but your attention is dedicated to other activities. How to dial the number in a quick way?
With a search through a long list? With the help of speech recognition? Yes, if the recognition works and doesn‘t confront you with wrong interpretations, then this could be the solution for you. But if you don‘t feel happy on trying various pronounciations of names to make the speech recognition work, what would you do? Browsing again through lists of names, which is too long-winded, too detailed and too time consuming?
No – zapDial is the solution.


With zapDial you find quickly and in an easy way the telephone number of your favorite contact, without searching the lists. On the basis of mapped gestures, which you draw in your own individual style on the display, your contacts will be called by a simple movement on the touchscreen.
Timeconsuming searches and error-prone touches in lists will not bother you anymore.
A vibrating phone informs you when the app is ready, so you don‘t even have to look on the display. Just make a gesture on the display and your iPhone will connect you to the selected contact.

How does zapDial work?

Select a contact from your address book and choose an individual gesture, which will be mapped to the contact‘s telephone number. Keep in mind that a gesture consists of a single stroke.
Setup is finished and you are ready to start. Just start the application and draw the gesture on the touchscreen to call a contact. A switchable feature allows you to choose calling a contact or sending a text.

Basic features:
gesture recognition for quick dialing
record function for individual gestures
direct link to your address book contacts
switchable options for user interface feedback

What’s New in this Version:
search in address book, record audio hints for your contacts, user interface improvements, new layout
