    Seniorengerechtes Design : aktuelle Studien im Technischen Design
    (2007) Maier, Thomas
    ‚Wer von „den Senioren“ spricht, macht bereits den ersten Fehler’, auch diesen Titel kann man sehr werbewirksam in der Zeitschrift Absatzwirtschaft lesen. Er beschreibt aber sehr treffend das Spannungsumfeld, in dem wir uns – das heißt das Forschungs- und Lehrgebiet Technisches Design am Institut für Konstruktionstechnik und Technisches Design (IKTD) – mit unseren Studien derzeit bewegen. Denn die unterschiedlichen Einstellungen und Werthaltungen der ‚Senioren’ sind genau so heterogen und facettenreich wie in anderen Altersgruppen. Für die Altersgruppe der Senioren wurden viele Begriffe beziehungsweise Synonyme wie zum Beispiel ‚Best Ager’, ‚Junge Alte’, ‚Silver Surfer’ beziehungsweise ‚Generation 50 Plus, Generation 55 Plus und Generation 60 Plus’ geprägt.

    Design and evaluation of new user control devices for improved ergonomics in flexible robotic endoscopy
    (2025) Heisterberg, Leander; Manfredi, Luigi; Wichmann, Dörte; Maier, Thomas; Pott, Peter P.
    Background: The ergonomics of flexible endoscopes require improvement as the current design carries a high risk of musculoskeletal injury for endoscopists. Robotic systems offer a solution by separating the endoscope from the control handle, allowing a focus on ergonomics and usability. Despite the increasing interest in this field, little attention has been paid towards developing ergonomic human input devices. This study addresses two key questions: How can handheld control devices for flexible robotic endoscopy be designed to prioritize ergonomics and usability? And, how effective are these new devices in a simulated clinical environment?
    Methods: Addressing this gap, the study proposes two handheld input device models for controlling a flexible endoscope in four degrees of freedom (DOFs) and an endoscopic instrument in three DOFs. A two-stage evaluation was conducted with six endoscopists evaluating the physical ergonomics and a final clinical user evaluation with seven endoscopists using a virtual colonoscopy simulator with proportional velocity and position mapping.
    Results and discussion: Both models demonstrated clinical suitability, with the first model scoring 4.8 and the second model scoring 5.2 out of 6 in the final evaluation. In sum, the study presents two designs of ergonomic control devices for robotic colonoscopy, which have the potential to reduce endoscopy-related injuries. Furthermore, the proposed colonoscopy simulator is useful to evaluate the benefits of different mapping modes. This could help to optimize the design and control mechanism of future control devices.
