Field Test of a User Friendly Toilet Prototype

(December 2004 - February 2005, as part of FRR research project)

Austrian flag Diese Seite auf Deutsch


Often toilets in the semi public area do not meet the needs of persons with functional limitations. The EU funded Friendly Rest Room (FRR) project developed new types of assistive toilets in order to provide new means for increasing autonomy for disabled and/or old persons. One of the toilet prototypes was installed at a day care centre for MS patients in Vienna in order to verify if it actually is able to improve the patientís quality of life.


A toilet system with adjustable height and tilt steered via a hand held remote control was installed as a replacement of a conventional toilet in an existing toilet room. The height of toilet could be changed between 44.6 cm and 76.8 cm, the tilt between 0 and 6.5 degrees. A hidden monitoring unit logged the movements of the toilet, the status of the buttons on the remote control, the door (open/close) and the alarm call (on/off) every 100 ms. The users wore mid range RFID cards around their necks which were read contact less when the user was sitting on the toilet. This allowed assigning the logged data to an individual user. Additionally to the technical data gathering sociological data were collected by carrying out participative observation. ADL scores from test participants were collected and field notes were taken by the researchers. The day centre is open each working day from 8am to 4pm. MS patients partly are using wheelchairs, partly rollators, partly crutches.

For showing the environment of the field test in more details, two 360 degrees photographs are available. One is taken directly in front of the toilet door, the other is taken from inside the toilet room. Note: Your browser needs a Java Applet Viewer to present the pictures.

Preliminary Results

The field test was carried out from December 2004 to February 2005 with a total duration of 59 days, thereof (due to holidays and weekends) 39 days with usage of the toilet. 29 primary users (MS patients) and 12 secondary users (nurses) participated. 316 toilet sessions took place, whereof 149 (47.2%) could be identified via RFID cards. Number of toileting events per day: min 2, max 14, average 8.1. The toilet tilt was moved between 0 degrees and 6.5 degrees, the height of the toilet between 43.6 cm and 67.9 cm. Outcome measurement based on QUEST delivered satisfaction rate of approx. 80%. The MS patients experienced increased autonomy and a higher level of dignity (e.g. being able to autonomously call the nurse via held remote control), and increased safety (e.g. better contact between feet and floor due to adjustable height).

Discussion and Presentation of First Results

It could be shown that a height and tilt adjustable toilet system actually is providing a higher quality of life for MS patients in daily life of a day care centre. For details please check the presentations given at the final conference of the FRR consortium:

Preliminary Conclusions and Ongoing Activities

As the installed toilet system has proven to actually enhance the quality of life of users it was decided to leave the system in daily use at the day care centre even after completion of the evaluation phase. (Contact: Ramona Rosenthal, email: ramona.rosenthal@cs.or.at)

The detailed data records are currently (February 2006) still waiting for being analysed. We are working on getting funding for corresponding publication of final results. (Contact: Paul Panek, email: frr@fortec.tuwien.ac.at)
