 اي ستي قطر هاد بس انتظرويو with Mr. Guelm Lewis. Mr. Guelm, can you tell us first about web accessibility and how the idea all started? Yeah, web accessibility is something that has been developed over time by predominantly or primarily the worldwide web consortium which is also known as W3C and one of the which countries are currently applying the web accessibility initiative or the tips of web accessibility. Okay, so what equipment or browsers or software that can the persons with disabilities have to possess in order to be able to access a website that has been developed specifically for them or an accessible website. So what equipment should they be having? Okay, so for an institution who would like to make its website accessible to visually impaired people or persons with disabilities generally is this step an expensive way to, I mean is upgrading the website to be accessible for all is it an expensive step for a company to take for any institution? So do you think that governmental and commercial entities would be equally interested to take such a step and upgrade their websites? Okay, so in your opinion what further web developments need to be done in the future to support what the web accessibility initiative calls for so what additional developments should be or are required in the future? Okay, so finally our last question would be that every company or any organization in general would always like to measure the results of its efforts so when a company or any institution takes the step of upgrading the website and making it more accessible how can it actually measure the outcome or the results of its step? How can it make sure that the web is really accessible and it has succeeded in its purpose? Okay, we'd like to thank you Mr. Gwetem Loews for your time and valuable insights. Thank you very much.
