Age Simulation and Sample Size

Prof. Dr. Simone Besemer and Prof. Dr. Simon Ottler from the Duale Hochschule Baden-Württemberg in Ravensburg visited SD&C in the north of Munich to inspect and evaluate  the Senior Suit Delta.

Despite their difference in their size, the age simulation suit fitted both professors, and a weight adjustment on one suit was quickly done. The tinnitus simulation impressed them, because the knew well that many people suffer from it. There were glad to be able to switch these sounds off again. The cervical collar significantly limited the mobility of their heads, and with regard to the elbow joints, a light wrapping of the bandages was sufficient, and both were almost not able to reach up to their own hairs. The simple variants of gloves produced a realistic and not exaggerated reduction of the sense of touch. As usual, visual performance was compared using font sizes on an opticians sheet. Without the simulation, the smallest font (1) could be read by both professors, with the optic’s visor folded down, both needed size (5) to (7). By carrying an empty crate of bottles over stairs, the visitors were able to experience themselves the effects of the reduced strength, and when throwing darts, to experience the effects of age simulation on coordination. Counting money in the simulation suit was of the practical importance, and when sitting in a vehicle, several restrictions were quickly noticed, such as a difficulty to reach for the seat belt.

The interesting question of the minimum size of a sample for market analyses was discussed. ISO 20282 requires a minimum size of 20 persons for usability tests, but recommends 50 or more. This also corresponds to the SD&C-known general industrial standard of meaningful tests in product development, although purely explorative studies sometimes want to get by with only three test subjects. For age simulation a study exists, in which 20 younger test persons in suits were compared with 20 real older test persons in numerous operations, and the results were consistent. An age simulation suit is thus a valid research instrument for demographic change. With the age simulation suit, the university ordered, students at universities will be able to investigate how Germany and Europe can be prepared for the rapidly approaching time when every second person in the country will be over 50 years old.

Introduction into Age Simulation at the Institute for Work Design in Düsseldorf

With respect to demographic change, there are many challenging tasks of modern work design for the institute to deal with. As an example, the necessity for job rotation of elderly workers in certain jobs (like tiler and roofer) due to ageing was discussed, when there typically are not enough alternative workplaces available for them in their companies, while these workers still have years left before retirement. The aquired SD&C Senior Suit Beta will be used by the institute to sensitize for topics like this and similar ones.

The mobility of the elderly is of high interest for us at SD&C. On the one hand, transportation means have to become barriere free, on the other hand the personnel has to be sensitized. We have therefore already cooperated with several automobile producers, with universities, automobile clubs, and transportation services. With the Ludwigshafener Traffic Services there is again one company more that is now going to deliver positive understanding of senior citizens into the local area. To read a schedule with less visual acuity, enter a bus with limited moveability, to pay a ticket with coins hard to identify, walking and taking place with deteriorated balance, and hearing station infos with slight deafness, is quite different from the expected. One just has to experience it for oneself. –

Prototyp of the new Senior Suit ® Delta is being tested

The prototype of the new age suit model Senior Suit ® Delta has been tested. The new ideas added to the previous model Age Suit 2011 include e.g. fasteners, which allow more easy access to the weights in their pockets, further speeding up the dressing process. These fasteners are required by us to hold the weights, even when the age suit is used upside down, although that does not happen often. The tests were showing positive results. Further new features include stiffening elements for back and shoulders, strip elements an both sides to restrict breath taking, air conditioning vents, stiffening elements for the knee- and elbow-bandages, a wider cartridge belt for the underarm weights. The new SD&C Senior Suit Delta will be available starting begin of April.

Der SD&C Senior Suit ® erreicht New York

Der SD&C Senior Suit ® erreicht New York. Wir sind ja mit der Alterssimulation schon gut in Europa herum gekommen, aber der Einsatz für unseren Kunden Grass Roots in New York Ende November war doch noch etwas Besonderes. Carmen aus Hamburg nahm den Einsatz für uns wahr, zusammen mit Einsätzen für die Swiss Re in Zürich und in London. Mehr dazu z.B. in dieser Pressemeldung. –>SD&C
