The Application “MedMate” is a tablet-based application which we developed for the medical domain. The principal purpose of the software is to update the patients’ charts automatically to a computer based, centralized database system from which the information can be accessed anywhere within the hospital at any time.


In order to identify the person holding the tablet, all doctors and nurses wear wristbands with integrated chips. Accordingly, the tablet can adjust the user interface.

With the technology of “Near-Field-Communication” (NFC) it is possible to detect the tablet’s current location. This can be useful to automatically retrieve information about a patient in their individual sickroom. It is also possible to identify patients by scanning wristbands with an analogous technology as already mentioned above.

Supporting the documentation of the patients’ treatment, the tablet saves doctors’ diagnoses through a voice-recognition software. The system saves the audio file and its textual representation to the server. To make typing on the tablet more efficient, the tablet provides an interface to a docking station with a keyboard.

The advantage of the system is that it simplifies the internal communication within the medical stuff, because all patients’ information is available simultaneously in any ward of the hospital. Another point is that staff members don’t need to digitalize analog notes made during a treatment. Therefore, nurses have more time left that can be spent with the patients.

Within the scope of a hospital it is inevitable to provide a solution for hygiene aspects. For this purpose the easy-to-use technology “photo activated disinfection” (PAD) is used.

Furthermore, it is conceivable to integrate a well-established pager system. It might also be desirable to know a doctor’s location at any time. This could be quite useful if there are issues to be discussed which involve several members of the medical staff. Another advantage is that ordering medication could be directly achieved through the data-processing system.

Affinity Diagram

After thorough evaluation of our interview transcripts, we proceeded by following the steps provided by a guest lecturer from Google to create an affinity diagram to help us with our further proceedings.

We started out by having everyone in our group post the most important information extracted from our interview transcripts to a wall, already considering categorizing the information into single groups.

Ward Round Scenario

Ward Round Scenario

Having then analyzed our interviewees’ main tasks within their professional lives in order to gain a more profound understanding of what features our device will have to be able to provide, we came up with an idea of a tablet device to help hospital’s staff members and doctors with their daily work. This tablet is wirelessly connected to the hospital’s server, on which all information about all patients is being stored. With this device, one can edit data through speech or keyboard input. Furthermore, the user’s identification as well as their current location can always be recognized through an integrated NFC-Chip.

We then visualized our concept by providing drafts of a possible scenario where our product might come in handy.

Research – Medical Domain

User Research, WS1112

In the sphere of the medical domain, there is a plethora of people interacting with each other. The aim of ‘Group 2’ is to investigate the involved parties and to work out suitable interface concepts in order to facilitate their work. We achieve this by researches of various subdomains. Therefore we were provided an insight into the work of a geriatric nurse, of an assistant who’s educated in technical anesthesia and of a pediatrician.

Even if many tasks within the strictly ordered working process are handled with the aid of already well-established electronic devices, the pervasive opinion is notable that the work with the computer to register all the patients’ information is very time-consuming. The consequence is that there might be restrictions with the patients’ treatment from a psychological point of view or it leads to extra hours.

As facilitators we extract from these researches the necessity to simplify the daily routine of the digital data acquisition and communication, respectively.
