Prompt:

Iterate a design of a handheld object.
Create a digital CAD file of the final iteration.

Tools Used:

Pink Foam Modeling
Solidworks

Problem:

VR Controllers currently either offer limited interaction, but fit easily in a pocket or bag (Samsung), or offer more diverse interactions, but are larger and more easily broken due to their shape (ex. Oculus).

Solution:

Create a robust controller for the advancing VR market that offers that offers a larger base of interactions while remaining easily portable and sturdy.

Process:

Iteration occurred over 15 models, with user testing occurring in between each iteration.

• Improved thumb indentation to improve grip and denote thumb-pad placement.

  • Allowing for users to pickup in the correct orientation while in VR.

• Buttons began vertical, then staggered. Finally the buttons reduced by one and increased in size.

  • Adjustments increased the range of hand-size that reported high levels of comfort during use.

• Front curvature was adjusted to a set angle and corners were increased in diameter

  • The angle and curves allowed for a hand position that more comfortably filled the palm. This caused the user’s grip to be more relaxed/comfortable while keeping full control of the controller.

• A thumb hook was added near the thumb-pad and adjusted in size/shape.

  • The hook protrusion catches on the user’s thenar webspace, keeping the controller in place , increasing control and reducing slipping.
