Development of Tests for Arm Coordination Impairment in Paralympic Classification [PDF]
Frontiers in Rehabilitation Sciences, 2022 BackgroundIn Paralympic sport, classification of impairment with the ability to detect misrepresentation of abilities is mandatory. In wheelchair rugby, there is currently no objective method to classify arm coordination impairment. In previous research,

Temporal properties of the speed-accuracy trade-off for arm-pointing movements in various directions around the body. [PDF]
PLoS ONE, 2023 Human body movements are based on the intrinsic trade-off between speed and accuracy. Fitts's law (1954) shows that the time required for movement is represented by a simple logarithmic equation and is applicable to a variety of movements.

Measurement of the Robot Motor Capability of a Robot Motor System: A Fitts’s-Law-Inspired Approach [PDF]
Sensors, 2013 Robot motor capability is a crucial factor for a robot, because it affects how accurately and rapidly a robot can perform a motion to accomplish a task constrained by spatial and temporal conditions. In this paper, we propose and derive a pseudo-index of

Performance Analysis of a Head and Eye Motion-Based Control Interface for Assistive Robots [PDF]
Sensors, 2020 Assistive robots support people with limited mobility in their everyday life activities and work. However, most of the assistive systems and technologies for supporting eating and drinking require a residual mobility in arms or hands.

Evaluation of intuitive trunk and non-intuitive leg sEMG control interfaces as command input for a 2-D Fitts's law style task. [PDF]
PLoS ONE, 2019 Duchenne muscular dystrophy (DMD) is a muscular condition that leads to muscle loss. Orthotic devices may present a solution for people with DMD to perform activities of daily living (ADL).

Cortical Correlates of Fitts’ Law [PDF]
Frontiers in Integrative Neuroscience, 2011 Fitts' law describes the fundamental trade-off between movement accuracy and speed: it states that the duration of reaching movements is a function of target size (TS) and distance. While Fitts' law has been extensively studied in ergonomics and has guided the design of human-computer interfaces, there have been few studies on its neuronal correlates ...

A study of hand-movement gestures to substitute for mouse-cursor placement using an inertial sensor [PDF]
Journal of Sensors and Sensor Systems, 2019 This paper examines the new study of hand orientation as a substitute for computer-mouse movement and is evaluated based on ISO/TS 9241 part 411: Ergonomics of human–system interaction-evaluation methods for the design of physical input devices.

Predictive feedback control and Fitts–law [PDF]
Biological Cybernetics, 2008 Fitts' law is a well established empirical formula, known for encapsulating the "speed-accuracy trade-off". For discrete, manual movements from a starting location to a target, Fitts' law relates movement duration to the distance moved and target size.
