Our application for children with developmental disabilities can help to sustain that problem by helping them to differ and understand colors. Although primarily intended for children with developmental disabilities this application may also be used by typically developing children. This was made possible by a special Accessibility mode which can be activated inside the application. Accessibility mode requires the user to press and hold the in-game buttons for a few seconds in order to activate them which effectively prevents the detection of unwanted random presses.","PeriodicalId":175742,"journal":{"name":"2018 International Symposium ELMAR","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115018273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite voice call as the basic communication, on-demand service is also video as advance way of communication. To have a video communication in LTE (Long Term Evolution) network, mobile operators should provide good radio conditions and enough bandwidth to support multimedia communications in general and video communication particularly. To achieve the required quality of multimedia communications via different applications, operators need to improve the coverage and the throughput capacity in wireless technology. This paper shows the results of the video quality measurements for Skype and Viber applications, in different radio propagation conditions in LTE network. Utilization of throughput and modulation schemes used during the communication are also measured and analyzed. Recorded video sequences are evaluated based on the feedback from the people (users) involved in the evaluation process.
