TRANSPORTATIONFocus: to incorporate Digital Human Modeling (DHM) early stages of the vehicle development and to improve driverposturecomfort(intermsofjointanglesandvision)withoutsacrificingstructuralintegrity.Methodology: consist of using my Human-in-The-Loop design framework for modeling and simulation, and utilize Virtual Reality (VR) tools to extend the advance visualization techniques during design process.

Results: jointanglediscomfortwereimprovedwhilemaintainingtheaerodynamicsandstructuralintegrityofthe vehicle. Center of gravity was further lowered. Future Work: includes a total-vehicle integrationdesign study,whichaims to formahighfidelitydigitalvehicle design system that manages and monitors engine simulation, steering controls, suspensions with DHM.

Concept

Focus: to create a user-friendly, light-weight, easy to use and a safe code cart to accommodate needs and limitations of nurses coming from different anthropometric backgrounds. Methodology: creating human-machine-interaction simulations for patent pending unique features (such as bi-directionaldrawers,adjustablehandles...etc.)throughmyHuman-in-The-Loopdesignframework.Results: percent capable summary of upper and lower limbs were improved and visual obscuration (cluttler) zones were cleared. Proposed cart model accomodates a wide range of nurses comparing to current models.Future Work: finalizing patent application, developingmarketing/sales plans and creatingmanufacturingdrafts for a possible large scale production opportunity.

USER-FRIENDLY WASH-MACHINE A STUDY OF DESIGNING FOR HUMAN VARIABILITY A.3

pg.7

CONSUMER GOODSFocus: to improve posture when loading-unloading of clothes of user groups coming from a wide-range of anthropometric population by utilizing Digital Human Modeling (DHM) during product development cycle. Methodology: to generate digital postures based on user study (data collection) and develop human-machinesimulationsbyusingHuman-in-the-Loopdesignframeworktofindoptimizedgeometry.

Results: door inlet size was increased for ease of access, pedestal height was optimized for different users, and overalldimensionsofthewash-machinewasfinalized.Future Work: to develop future wash-machines that accommodate different needs and offer comforting features for users.
