• Potential benefits include the possibility of making ergonomic evaluations ofthe person-environmental fit using virtual techniques during the designprocess. This can improve communication between designers, consumers andpolicy makers.• The HADRIAN software package currently includes link lengths, range ofmotion, posture prediction algorithms and functional task information of 40individuals without disabilities, 40 ambulant individuals with a disability, and 20users of wheeled mobility devices.• Based on the structural and functional anthropometric data, designers can testvirtual tasks in virtual environments to determine the percentage of individualswho have the ability to complete a task in the specific context of theenvironment and also people with specific characteristics, e.g. an older frailperson with left side paralysis due to stroke. Reasons why a design cannot beused by a user group or individual become clearly obvious in the virtual tasksimulations.• Perhaps the largest limitation of the approach is the limited amount of data thatis currently available for testing. Additional individuals and tasks are neededfor the design tool to provide a more accurate understanding of how a designwill affect usability. The software is designed to accept new activities and newpeople with little difficulty.Mannequin Pro Human Modeling Design Tool, Dan HeltAbstractThis presentation provided an overview of the Mannequin Pro ergonomic designtool. Early versions of a digital wheeled mobility user model were described. Thesoftware allows the user to examine the fit between a fairly simple static virtualmodel of a user and the environment to be evaluated. The current version of thesoftware also allows simple three-dimensional biomechanical analysis.Key Points• Currently the Mannequin Pro software assumes that the structural dimensionsof an ambulant adult are similar to the wheeled mobility user. Negotiations areunderway with the Center for Inclusive Design and Environmental Access toobtain structural data of wheeled mobility users that would introduce moreaccurate digital "Mannequin" models of this user group.General Discussion of Human Modeling Applications toDetermine Space Requirements for Wheeled MobilityWhile digital human models provide information that cannot be collected withconventional anthropometric methods, it is not clear to the standards developers ifuse of such tools will be of great value. Typically, the questions that designersSpace Requirements for Wheeled Mobility 32
and code officials need answered do not require the level of detail provided bydigital human models and simulations, and, development and purchase of digitalhuman models is costly. Further discussion is needed to explore how digitalhuman modeling and simulation methods can be used effectively in codedevelopment.For both design and code development, digital human models must be validated.Usually only components of the models (e.g., posture prediction for specific tasks)are evaluated, and there is not very much information about the errors associatedwith using digital human models in design.Space Requirements for Wheeled Mobility 33
