The results of the analysis and subsequent design recommendations are compared with the actual design evolution of the iPhone product line. For certain subsystems, this comparison reveals a divergence in Apple’s design decision-making from the evolution recommended by the GVI technique.
The design of compliant bistable micromechanisms granted U.S. Patent #7075209.Read more
A case study involving the layout of the interior of a passenger car is presented, focusing on simultaneous placement of the seat and steering wheel adjustment ranges. Tradeoffs between adjustability, driver accommodation, and exterior vision are explored under this paradigm. These results are contrasted with those obtained using boundary manikins.Read more
For a truck driver operating the shift lever of a manual transmission, excessive shift forces can necessitate pulling on the steering wheel with the other hand to maintain balance, creating a potentially unsafe condition.Read more
Seated center of pressure excursion capability can be used for patient evaluation in a clinical setting and in universal design. A quantification of excursion capability across age and anthropometry has not been previously reported, although some research suggests that the ischial tuberosities are the support structure limiting the excursion. Methods. Thirty-eight neurologically healthy adults ranging in age from 21 toRead more
Vehicle packaging can be improved through the application of optimization and a new strategy for modeling driver variability.Read more
The approach is demonstrated on a novel human-reach experiment where the selection of sampling points adapts to the individual test subject.Read more
Ballistic motion is used to increase the reach capability of people with SCI.Read more
A categorization of reach targets into four zones differentiated by torso kinematics is proposed.Read more
The location of the center of pressure throughout each motion was calculated using inverse dynamics and was found to be a good indicator of the strategies employed and the behavior differences between the two groups.Read more
