A Saliency-driven Video Magnifier for People with Low Vision.

Proc 17th Int Web All Conf (2020) 2020 Apr 20;2020. Epub 2020 Apr 20.

Department of Computer Science, Stony Brook University, Stony Brook, NY, USA.

Consuming video content poses significant challenges for many screen magnifier users, which is the "go to" assistive technology for people with low vision. While screen magnifier software could be used to achieve a zoom factor that would make the content of the video visible to low-vision users, it is oftentimes a major challenge for these users to navigate through videos. Towards making videos more accessible for low-vision users, we have developed the SViM video magnifier system [6]. Read More

Waterloo Road, Kowloon, Hong Kong, China; HKBU Institute of Research and Continuing Education, Shenzhen, China; State Key Laboratory of Environmental and Biological Analysis, The Hong Kong Baptist University, Waterloo Road, Kowloon, Hong Kong, China. Electronic address:

Many rapid antimicrobial susceptibility testing (AST) methods have been proposed to contain clinical antimicrobial resistance (AMR) and preserve the effectiveness of remaining antimicrobials. However, far fewer methods have been proposed to test AMR in resource-limited conditions, such as for frequent safety screenings of water/food/public facilities, urgent surveys of massive samples during a pandemic, or AMR tests in low-income countries. Rapid AST methods realized thus far have a variety of drawbacks when used for such surveys, e. Read More

Perceived Motion and Operational Momentum: How Speed, Distance, and Time Influence Two-Digit Arithmetic.

Front Psychol 2021 13;12:653423. Epub 2021 Jul 13.

University of Warsaw, Warsaw, Poland.

Operational momentum was originally defined as a bias toward underestimating outcomes of subtraction and overestimating outcomes of addition. It was suggested that these estimation biases are due to leftward attentional shift along the mental number-line (spatially organized internal representation of number) in subtraction and rightward shift in addition. This assumes the use of "recycled" mechanisms of spatial attention, including "representational momentum" - a tendency to overestimate future position of a moving object, which compensates for the moving object's shift during preparation of a reaction.
