28 開拓人類知識的版圖 This technology enables viewers to watch images with high-quality visual effects with ordinary 3D display devices. It has a wide range of applications, including 3D movies, games, and other digital visual entertainment applications. Hong Kong Sign Language Browser The Centre for Sign Linguistics and Deaf Studies (CSLDS) of the Department of Linguistics and Modern Languages launched the Hong Kong Sign Language Browser on 23 January 2013, which is the first comprehensive online database of Hong Kong Sign Language (HKSL). The browser was funded by the Labour and Welfare Bureau of the HKSAR as a public education activity on rehabilitation. HKSL Browser is an online platform devoted to the recording of lexical signs and their background information, including frequency of usage, users’ age distributions, origin of the signs, etc. There are about 1,100 HKSL lexical items in the database and it will be continuously enriched and updated by the CSLDS. The database also includes videos of demonstrations and lexical variations used by different deaf organizations. The browser is aimed at promoting HKSL to the public and supporting sign language related activities, such as deaf education and sign interpretation, as to meet the needs of the deaf community. 計算機科學與工程學系黃田津教授及其研 究團隊，利用人類雙眼視覺的自然融合能 力，開發出「雙目立體影調融合」技術。 人類雙眼猶如兩個獨立的視覺感受器，左 右眼看到有差異的影像，大腦會自然地把 這兩個影像合併。研究團隊就利用人類這 種視覺特性，從一個畫面產生兩幅圖像：一 幅顯示光暗變化產生的對比，另一幅則顯 示明暗處的紋理細節。用家戴上 3D 眼鏡看 到這兩幅有差異的圖像，會在大腦中自動 融合，從而能清晰看到 3D 畫面中強烈的光 暗對比、豐富的色彩和圖像紋理細節。 利用該技術，普通的 3D 顯示設備也可達到 高質素的視覺效果，日後可廣泛應用於電 影、遊戲或其他數碼影像和娛樂行業。 香港手語瀏覽器 語言學及現代語言系手語及聾人研究中 心在 2013 年 1 月 23 日推出「香港手語瀏覽 器」，這是全港首個集大成的網上香港手語 資料庫，獲香港特區政府勞工及福利局康 復服務公眾教育活動資助。 「香港手語瀏覽器」是一個以手語語言學 為基礎的網上平台，現時收集了約一千 一百多個香港手語詞彙，紀錄其背景資料 黃田津教授（右）與楊軒博士 Prof. Wong Tien-tsin and Dr. Yang Xuan
