We're pleased to share the latest developments in the mechanical design of our project, aimed at creating a user-friendly interface for virtual interaction. Let's delve into the three main sections of our design: the glove, the wrist mount, and the forearm assembly. Below are images demonstrating how our device will be worn by end-users.
The Glove
The glove serves as the primary interface between users and the virtual environment. We've integrated essential components such as the flex sensor, haptic feedback unit, and a specialized ring for seamless movement within virtual spaces. Lightweight and breathable cotton gloves ensure a universal fit for users of all sizes. The flex sensor and haptic module are securely stitched into designated pockets within the glove, held in place with adhesive for functionality and durability. The ring, affixed with double-sided tape, provides placement for the thumbstick, facilitating navigation within the UI and virtual environment.
Next Steps
After testing, we found the need to enhance adaptability for various finger sizes. We've implemented a Velcro fastening solution for a one-size-fits-all design, allowing users to adjust the strap independently with M3 set screws.
The Wrist Assembly
The wrist mount houses the peltier module and utilizes a Velcro strap mechanism for universal fitment. The adjustable strap caters to diverse wrist sizes and enables users to regulate tightness, influencing heat transfer between the peltier and the skin. Small rails on the sides facilitate the insertion of the peltier module into the housing.
Next Steps
We plan to expose the peltier's top surface area to expedite cooling for improved performance.
The Forearm Assembly
The forearm assembly houses batteries, controllers, and other electronic components, featuring a Velcro fastening system for universal fitment. By redistributing the device's weight to the forearm, we prioritize user comfort and minimize strain during extended usage, ensuring seamless interaction with virtual environments.
Next Steps
To enhance stability and usability, we've implemented M5 heat insert holes for set screws and reduced clearances to reducing sliding on the battery. Additionally, adjustments have been made to improve 3D printed quality and accommodate alternative battery orientations during testing.
Summary
In summary, our mechanical design focuses on functionality and adaptability, prioritizing user comfort and immersive feedback. Stay tuned for further updates as we continue refining our project.
