OptiVID Tool

In OptiVID, we implement two technical solutions:

  1. Webplayer: On a separate website, users can create an individual profile, which is subsequently applied to YouTube videos. The creation of individual optimization profiles and their application takes place directly via the easy-to-use website, i. the user does not have to install software, only a modern web browser is needed
  2. PC video player: In addition, we develop and implement a desktop application in order to be able to view individually optimized local videos and online videos on the PC.

Currently our software implementations are under development. For mid-2019, it is planned to publish more information (e.g., screenshots, demos, etc.) here. If you are already interested in the software, please send us an e-mail.

Project consortium

AIT Austrian Institute of Technology GmbH

The AIT Austrian Institute of Technology takes a leading position in the Austrian innovation system and a  key role in Europe as the RTO focusing on the key infrastructure topics of the future. The Center for Technology Experience deals with fundamental questions on the interaction between people and technology. We don’t just use technology, we live with it. Much more deeply than ever before, dealing with technology involves us emotionally, intellectually, and sensually. Based on interdisciplinary principles we investigate qualities, forms of interaction and new methods and tools. User experience research, experience driven innovation as well as new modalities of interaction have evolved into prominent and required building blocks towards future innovative and successful technologies, applications and services. The Center for Technology Experience supports public and private customers with the newest scientific approaches and methods to develop them.


VIDEBIS GmbH was founded in 1987 as a very small enterprise consisting of only 3 persons, with the aim to enhance the quality of life of blind people through assistive technologies. Our goal is, and always has been, to find the solutions best suited to the individual needs and requirements of our clients, be it at their workplace, throughout education or in their private lives. As of today, VIDEBIS has grown to 31 employees and has greatly widened its expertise, now also providing specialized solutions in the vast low vision field as well. More than 30% of our employees are blind and visually impaired themselves and thereby experts through their own experience in the application of assistive technologies over many years. They are the ones who support and train the clients, who ensure quality of new and serviced devices and much more.
Our way of working is to provide support and solutions for our clients all in one place. Our specialized opticians and our low vision and blind experts find out, together with the client, what’s wanted and needed and work on the best suitable solutions. We also assist our clients in finding possibilities to finance the devices. Furthermore we provide technical support and service, and we train clients, teachers, and representatives of organizations etc. in the use of assistive technologies and widen their perspectives in showing them what’s possible.

Hilfsgemeinschaft der Blinden und Sehschwachen Österreichs

The Hilfsgemeinschaft – the Austrian Association in support of the blind and visually impaired is an independent non-profit-organisation founded in 1935. With more than 4.500 members, it is Austria’s oldest and largest self-help organisation to improve the conditions and standards of living of its clients. The Hilfsgemeinschaft is almost entirely funded by donations and voluntary financial contributions which are also tax-deductible. In 2001, we were awarded the Austrian seal of approval for donations (“Österreichsiches Spendengütesiegel”). The membership in the Hilfsgemeinschaft is free of charge for blind or visually impaired clients offering access to a broad variety of services, which are even complimentary at times.


In the project OptiVID, beside technical implementation tasks, we also publish scientific results in high-quality, peer-reviewed conferences and journals. Please find here an overview about OptiVID-related publications.

Sackl, A., Schatz, R., Suette, S. and Tscheligi, M. (2019) “From Low Vision to High Quality: Video QoE Enhancement for Visually Impaired Users”, Proceedings of the Eleventh International Conference on Quality of Multimedia Experience (QoMEX), Jun. 5-7, Berlin, Germany [accepted].

In this paper, we investigate the impact of real-time video enhancement techniques on video Quality of Experience (QoE) for users with low vision. To this end, we present the results of a lab-based user study, in which participants with low vision utilize a web-based media player to configure individual video quality enhancement filters (e.g. increased contrast, strong edge enhancement and lowered brightness) depending on types of content. Additionally, for each test participant we measured the visual performance to describe how low vision impacts video QoE. Our results show, that individual video quality filters positively impact the experience of the quality dimensions detail, text and content. Furthermore, we discuss insights from qualitative feedback from participants regarding overall utility and User Experience (UX) aspects of real-time video enhancements.
