• Description:
  Significant (Key) Findings: A kinematic model of the human hand is developed that determines how the hand bones move with respect to each other. The kinematic model, when integrated into the CAD model, allows the modeled hand to be posed in real configurations. The ability to pose the modeled hand realistically is necessary to understand how the hand would interact with a proposed tool or interface. Translation of Findings: The kinematic model provides the framework for integrating other models (kinetic and predictive). The fully integrated model (Phase II) will allow for optimizing the design of tools and interfaces to reduce risk and increase access and functionality. Outcomes/Impact: Consider an engineer/designer working with a piece of 3D geometry that represents a new hand held device. With the proposed integrated suite of models, that engineer/designer may call up different sized animated hands in the same CAD environment as the new device and accurately place the device within the hand based on hand contact points and visual requirements. The software program will allow the engineer/designer to visualize the feasible design space (e.g. the work volume of the thumb) related to trigger/switch positions and grasp contacts of the device. An iterative process, wholly with use of a computer, can thus be used to generate an optimized design that decreases risk from awkward postures and increases access and functionality through optimized geometry of the device.
