Towards Adaptive Biodynamic Feedthrough Modeling for Touchscreen Applications

Given the expected increase of automation in the vehicles of the future, touchscreens are expected to be used in a wide variety of scenarios, including the ones that can become safety-critical.<br/>One disadvantage of the direct interaction approach that characterizes touchscreen operation is the feedthrough of accelerations through the human...

Effect of Turbulence Intensity and Variability on Model-Based Biodynamic Feedthrough Mitigation with Touchscreen Dragging Tasks

Recent aircraft have seen the implementation of touchscreens (TSCs) on the flight deck, in sight of more intuitive and direct human-machine interactions. Biodynamic feedthrough (BDFT), i.e., the transfer of the aircraft’s accelerations through the pilot’s body to the control inputs, is however still cause for concern, preventing safe and...

Model-Based Mitigation of Biodynamic Feedthrough for Touchscreen Dragging Tasks in Turbulence

The anticipated arrival of touchscreens on the commercial flight deck will make pilots vulnerable to erroneous screen inputs under vibration, creating a potential safety hazard. Biodynamic feedthrough (BDFT) has shown to be a key obstacle in continuous touchscreen dragging tasks under simulated turbulence, disrupting task performance. This...

A Cybernetic Analysis of Biodynamic Effects in Turbulence on Touchscreen Continuous-Dragging Tasks

Implementation of touchscreen technology on the flight deck has already been announced by multiple aircraft manufacturers. However, a number of unsolved challenges still stand in the way of large scale implementation. One of these challenges comes from using touchscreens as input device in a highly dynamic and turbulent environment. Effects from...

Admittance-adaptive model-based approach to mitigate biodynamic feedthrough

Biodynamic feedthrough (BDFT) refers to the feedthrough of vehicle accelerations through the human body, leading to involuntary control device inputs. BDFT impairs control performance in a large range of vehicles under various circumstances. Research shows that BDFT strongly depends on adaptations in the neuromuscular admittance dynamics of the...

Measuring, modeling and mitigating biodynamic feedthrough

Vehicle accelerations affect the human body in various ways. In some cases, accelerations cause involuntary motions of limbs like arms and hands. If someone is engaged in a manual control task at the same time, these involuntary limb motions can lead to involuntary control forces and control inputs. This phenomenon is called biodynamic...
