Mobile devices, per definition, are supposed to assist in organizing all kinds of things, also tasks of course, because usually such devices are always at hands. But due to the very limited and time consuming possibilities to interact with such devices many fall back to other means to organize their life, like a simple pencil and paper. We developed a collaborative task repository that facilitates collaboration and teamwork, but on the other hand demands that all tasks have to be entered into that system. Therefore a smart and userfriendly interface to that repository is mandatory. This work presents concepts on how to improve the user interface of mobile devices so that capturing tasks on-the-go becomes feasible. We propose to move away from display driven user interfaces to more sophisticated interfaces that utilize all the sensors and actors of current mobile devices.
