In this paper a barcode-based system to help the visually impaired and blind people identify objects in the environment is introduced. The system is based on the idea of utilizing QR codes (two-dimensional barcode) affixed to an object and scanned using a camera phone equipped with QR reader software. The reader decodes the barcode to a URL and directs the phone’s browser to fetch an audio file...

Critically oriented researchers within Human-Computer Interaction (HCI) have fruitfully intersected design and critical analysis to engage users and designers in reflection on underlying values, assumptions and dominant practices in technology. To successfully integrate this work within the HCI community, critically oriented researchers have tactically engaged with dominant practices within HCI...

In this study the five-phase method and a parallelized invocation of evalglare has been used, to evaluate performance microstructure Low-E window w/wo external blind, in terms glare. The first part results investigates how Bidirectional-Scattering-Distribution-Functions, BSDF, aBSDF (Aperture BSDF) properties bias predicted glare through microstructure, linking BSDF rank saturation resolution c...
