En este trabajo de investigación se busca recopilar y analizar información sobre la forma en la que la música pregrabada fue utilizada en los videojuegos desde la década de los 90. Para ello se ha empezado por brindar una serie de antecedentes que conforman el panorama en el cual apareció la tecnología que hizo posible la inclusión del audio pregrabado en los juegos de video y, posteriormente, su desarrollo e impacto en esta forma de entretenimiento en los años 90. Luego, se analizan distintos aspectos de la música pregrabada a lo largo de la década de los 2000, como la mayor calidad de audio, su vigencia a lado del chiptune, su tal vez excesivo parentesco con la música para otros medios como el cine, entre otros. Por último, se identifica cómo a pesar de la mayor tecnología disponible desde el 2010, varios usuarios aún prefieren videojuegos breves de calidad sonora chiptune y gráfica de pixel art, las cuales también inspiraron subgéneros musicales novedosos como el synthwave y el math rock. Por estos hechos, mediante el análisis de recursos estilísticos musicales tanto del chiptune como de la música pregrabada, se sugiere la composición de música pregrabada para videojuegos que imite o utilice como referencia el estilo chiptune de los videojuegos clásicos como una nueva opción que permitiría el desarrollo de la música para videojuegos. / This work of research seeks to collect and analyze data about the way pre-recorded music was used in videogames since 90’s decade. The research starts by bringing background information about the situation in which pre-recorded audio started to be used in videogames to follow with its development and impact in this type of virtual entertainment along the nineties. Then, it analyzes aspects of pre-recorded audio in 2000’s decade like the better audio quality; the importance of pre-recorded audio beside its classical, noisy and still used chiptune; the perhaps excessive similarity with movie music, etc. . By last, it is identified how some players still prefer classic pixel art games with chiptune audio despite the technology available nowadays and also how chiptune music inspired new music subgenres like math-rock and synthwave. Due to this, through analyzing musical resources and patrons of both pre-recorded and chiptune music, the investigation suggests the composition of pre-recorded music for videogames which use as a reference the chiptune style. It’d mean a step forward for the development of videogames music due to the popularity of both chiptune classic and pre-recorded moder music. / Trabajo de investigación

>Magister Scientiae - MSc / Many South African Deaf people use their mobile phones for communication with SMSs yet they would prefer to converse in South African Sign Language. Deaf people with a capital `D' are different from deaf or hard of hearing as they primarily use sign language to communicate. This study explores how to design and evaluate a prototype that will allow a Deaf person using SASL to tell a hearing doctor how s/he is feeling and provide a way for the doctor to respond. A computer{based prototype was designed and evaluated with the Deaf people in a previous study. Results from the user trial of the computer{based mock{up indicated that Deaf users would like to see the prototype on a cell phone. Those user trial results, combined with our own user survey results conducted with Deaf people, are used as requirements. We built a prototype for a mobile phone browser by embedding SASL videos inside XHTML pages using Adobe Flash. The prototype asks medical questions using SASL videos. These questions are arranged in an organized way that helps in identifying a medical problem. The answers to the questions are then displayed in English and shown to the doctor on the phone. A content authoring tool was also designed and implemented. The content authoring tool is used for populating the prototype in a context free manner allowing for plug and play scenarios such as a doctor's office, Department of Home A airs or police station. A focus group consisting of Deaf people was conducted to help in the design and pilot trial of the system. A final user trial was conducted with more than thirty Deaf people and the results are presented and analyzed. Data is collected with questionnaires, semi-structured interviews and video recordings. The results indicate that most of the Deaf people found the system easy to learn, easy to navigate through, did not get lost and understood the sign language in the videos on the mobile phone. The hand gestures and facial expressions on the sign language videos were clear. Most of them indicated they would like to use the system for free, and that the system did not ask too many questions. Most of them were happy with the quality of the sign language videos on the mobile phone and would consider using the system in real life. Finally they felt their private information was safe while using the system.
