PURPOSE To develop in an interdisciplinary approach between ophthalmology and design areas an ergonomic +22-diopter 50-mm aspheric hand magnifier for low vision. METHODS An aluminum cylinder was cut, processed using a lathe and carved to produce a ring that accommodated a 50-mm aspheric lens, with an external depression not to slide from the holder's fingers. A cylindrical steel bar was cut, ...

We describe our work on haptic holography, a combination of computational modeling and multimodal spatial display, which allows a person to see, feel, and interact with three-dimensional freestanding holographic images of material surfaces. In this paper, we combine various holographic displays with a force-feedback device to render multimodal images with programmatically prescribed material pr...

Abstract The Swiss-type lathe is a specialized turning machine of Swiss-origin with wide range applications across the precision machining industry. Its unique features enable it to mass produce parts at high speeds and precision. However, complex non-symmetric structure tool makes particularly susceptible adverse effects thermal influences. These internal external influences cause an offset ce...
