Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

2.3K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Bending of Curved Members - Neutral Surface

209
In curved beams, unlike straight beams, the stress distribution across the cross-section is not uniform due to the beam's curvature. This non-uniformity arises because the neutral axis, where stress is zero, does not align with the centroid of the section. In a curved beam, the strain varies along the section as a function of the distance from the neutral axis.
Consider the curved member described in the previous lesson. According to Hooke's law, which relates stress to strain within...

    Area of Science:

    • Human-Computer Interaction
    • Virtual Reality Design

    Background:

    • 3D sketching in virtual reality (VR) offers immersive design experiences but suffers from a lack of depth perception cues.
    • Scaffolding surfaces are commonly used to aid stroke accuracy in VR, but their efficiency can be limited.
    • The non-dominant hand often remains idle during VR sketching, presenting an opportunity for interaction enhancement.

    Purpose of the Study:

    • To introduce GestureSurface, a novel bi-manual interface for 3D sketching in VR.
    • To leverage non-dominant hand gestures for operating and manipulating scaffolding surfaces.
    • To evaluate the efficiency and user experience of gesture-controlled scaffolding in VR sketching.

    Main Methods:

    • Developed GestureSurface, a system utilizing non-dominant hand gestures for scaffolding control and the dominant hand for drawing.
    • Designed a set of non-dominant hand gestures for creating and manipulating scaffolding surfaces.
    • Integrated primitive surfaces for automatic scaffolding assembly.
    • Conducted a user study with 20 participants to evaluate the system.

    Main Results:

    • GestureSurface enables users to efficiently create and manipulate scaffolding surfaces using their non-dominant hand.
    • The bi-manual approach significantly improves the efficiency of scaffolding-based 3D sketching in VR.
    • User feedback indicated reduced fatigue compared to traditional methods.

    Conclusions:

    • GestureSurface offers an effective solution for improving 3D sketching in VR by engaging the non-dominant hand.
    • The bi-manual interaction paradigm enhances user efficiency and comfort in virtual reality design tasks.
    • Gesture-controlled scaffolding presents a promising direction for future VR interaction design.
