EXPLORE PT. 2

User Testing Insight

---

We found helmet placement awkward; wrist and chest placements were more comfortable. The separate camera and display distracted from tool use. Testing different placements revealed the best angle, and simulating firefighting tasks showed the wearable added stimulation but needed better integration for ease of use.

R4 Intermediate CAD

---

In this round, we refined the final design by exploring several concepts. The wrist-attached device provided a comfortable handle, but the detachable camera and display were fragile and hard to reattach. The two-sided design clarified the form but felt restrictive. These insights helped identify key features for the final design.

R5 Rough Prototyping

---

We created a rough prototype of our final concept, experimenting with different pivot point locations for the handle. We tested it with gloves to ensure the motions worked with existing PPE, and adjusted hand placement to prevent accidental button presses.
