MemoClip II Project

MemoClip II Project

One of the major problems in the modern society is information overload. Today many technologies are applied to support the human memory in coping with this situation. The most traditional technique in use is to put down important facts on paper. New are devices that are capable of actively reminding the user of upcoming appointments, like electronic schedules and personal digital assistants (PDAs). These new technologies enable us to create "smarter" tools that can provide enhanced functionality to the user everywhere and at all times.In the MemoClip project we research how the human memory can be supported by these technologies. The focus here is especially on supporting the capacity of remembering of the user by identifying and processing various contexts like time, location and situation. The contexts to be identified thereby are associated with information entered by the user in a way that an enhanced reminder application can evolve.

Memory aids have a long tradition in human history and they developed from anonym reminders like the "knot in the handkerchief" over written reminders on paper to proactive reminder tools of today that make use of modern technologies to provide the user with comfortable schedulers.

Today we know form the findings in cognitive science that humans tend to organize their lives, surroundings and workspace by different criteria. One obviously is time, another is space. This you can easily see if you observe yourself in how you place things on your desk or when you put things you do not want to forget at home near the door. But still there are many more factors that influence the remembering of dates and tasks beyond time and location. With the MemoClip and MemoClip II we research the potential of the extension of established reminder systems like standers PDAs that today make mainly use of only the temporal context of tasks and events to multi context aware proactive reminder systems that are capable of also taking location and the general situation into account when triggering a reminder event.

For example the MemoClip II can be used to set a reminder event to buy beverages at the superstore in case you have enough time and you are near the store and you have your car with you.


The first version prototype of the MemoClip I was implemented in custom hardware. The MemoClip I was able to process location based events only. Users had to interact with the device via a personal computer that was used to enter new reminders and associated them with locations. The MemoClip made use of a custom IR based location system for indoor localization. The reminder of this first MemoClip consisted of beeping alarm and a short message that was displayed on the device itself. The evaluation of this first prototype proved the value of context based reminders apart form time based ones.

With the MemoClip II we consequently extend the MemoClip I to a context aware personal reminder and schedule device. The hardware is now based on a common PDA device that is equipped with a GPS module for outdoor positioning and a Smart-Its device for sensing and processing of environmental and user contexts.

In a next step the software was be ported to a PDA device of the latest generation (PocketPC 2002) including a high resolution full color display and high bandwidth WLAN connection.
