| dc.description.abstract | 隨著電腦科學和科技迅速的發展，在人們日常生活周遭中有大量的虛擬實境應用被實現。人們可以憑藉著這些虛擬實境應用來學習某些知識或模擬某些特殊的議題環境，例如學習音樂、學習駕駛汽車、學習各項運動...等。然而，目前並沒有一個合適且具有可攜性的模擬DJ(Disc Jockey)的虛擬環境應用被實現。
基於前述理由，我們將在這篇論文中實做一個 'Virtual Mobile DJ' 系統。在系統創建的過程中，我們探討，有關於Linux的聲音系統、UDA1341編解碼器、嵌入式系統下OSS (Open Sound System)音效驅動應用以及如何不靠硬體支援的情況下有效的控制MP3格式的音效檔案…等議題。最後我們提出一個合適且簡潔的使用者介面和說明如何在觸控螢幕上操作這一個系統。 | zh_TW |
| dc.description.abstract | Along with the prosperous developments of computer science and technology, there are a large number of applications of virtual environment have been realized in people’s daily lives. People could learn some specific subjects or knowledge, such as playing music, driving a vehicle, exercising and so on, via these applications. However there is no proper and mobile DJ (Disc Jockey) relevant application be implemented nowadays.
Based on this point, the “Virtual Mobile DJ” system is implemented on an embedded system in this thesis. During construction procedure of the system, we explored on Linux sound system, the UDA1341 codec, OSS (Open Sound System) driver on an embedded system environment, and how to control MP3 format data on an embedded system without hardware support. And then a proper and clear user interface made by Qt GUI framework is proposed. Finally, a user could manipulate the “Virtual Mobile DJ” system by touching the interactive touch-screen GUI functionality in embedded system platform. | en |
