AbstractWith the development of mobile technologies, voice search is becoming increasingly important in our daily lives. By investigating the general usage of voice search and user perception about voice search systems, this research aims to understand users’ voice search behavior. We are particularly interested in how users perform voice search, their topics of interest, and their preference toward voice search. We elicit users’ opinions by asking them to fill out an online survey. Results indicated that participants liked voice search because it was convenient. However, voice search was used much less frequently than keyboard search. The success rate of voice search was low, and the participants usually gave up voice search or switched to keyboard search. They tended to perform voice search when they were driving or walking. Moreover, the participants mainly used voice search for simple tasks on mobile devices. The main reasons why participants disliked voice search are attributed to the system mistakes and the fact that they were unable to modify the queries.

Music video combines moving images with a preexisting song. The narrative implied by a music video’s visual content can either support or seem at odds with the narrative suggested by the song’s music and lyrics, in ways that have fascinating repercussions. In this video, we explore four different relationships between image and sound and how these interactions influence our interpretation of music video.

Traditional television coexists with formats that originated on the internet, as well as on-demand consumption, paid television, and other audio-visual content distribution platforms. Audience data reveal a steady decline in television viewership, and digital technologies now allow any citizen to produce audio-visual content and distribute it for mass consumption through the internet. Given this new audio-visual ecosystem, the aim of this research is to ascertain whether there are any signs of a crisis regarding the dominance of television as a means of disseminating the products of the culture industry. Disinterest or indifference toward conventional programming by users would reveal a danger to the broadcast industry. In contrast, the consumption of television products through other channels would imply the retention of television audiences through the internet. This study analyzes perceptions regarding television through five online discussion groups. Three conclusions can be drawn: Firstly, television holds a prominent place in the daily lives of those who use it, including the youngest participants, despite the fact that audiences have declined in recent years. The second conclusion states that the perception of television is positive and associated with disengagement, relaxation, and family gatherings, which can be combined with individual consumption at other times of the day. As a third conclusion, this study reveals the high degree of compatibility between the internet and television screens, as new forms of consumption are emerging, yet there is still a predominant interest in content on television and from the mass culture industry. Resumen La televisión tradicional convive con formatos originados en internet, con el consumo bajo demanda, con la televisión de pago y con otras plataformas de distribución de contenido audiovisual. Los datos de audiencias muestran un descenso continuado de telespectadores y las tecnologías digitales permiten a cualquier ciudadano producir contenidos audiovisuales y distribuirlos para el consumo masivo a través de la Red. Ante este nuevo ecosistema audiovisual, el objetivo de esta investigación es comprobar si se pueden advertir signos de una crisis de la supremacía del televisor como medio de difusión de industria cultural. El desapego o indiferencia de los usuarios hacia la programación convencional evidenciaría un peligro para la televisión. Al contrario, el consumo de productos televisivos a través de otras pantallas implicaría el mantenimiento de las audiencias televisivas a través de internet. La investigación analiza las percepciones sobre la televisión mediante cinco grupos de discusión online. Se extraen tres conclusiones. La primera, que la televisión ocupa una posición relevante en la cotidianeidad de los participantes, incluidos los más jóvenes, a pesar de que las audiencias han descendido en los últimos años. La segunda, que la percepción sobre la televisión es positiva y se asocia a la desconexión, el relax y a un momento de reunión familiar compaginable con consumos individualizados en otros momentos del día. Tercera, el estudio demuestra el alto grado de compatibilidad entre internet y la pantalla del televisor porque surgen nuevas formas de consumo, pero se mantiene un interés predominante por los contenidos televisivos y de la gran industria cultural.

Content based image retrieval (CBIR) is one of the field for information retrieval where similar images are retrieved from database based on the various image descriptive parameters. The image descriptor vector is used by machine learning based systems to store, learn and template matching. These feature descriptor vectors locally or globally demonstrate the visual content present in an image using texture, color, shape, and other information. In past, several algorithms were proposed to fetch the variety of contents from an image based on which the image is retrieved from database. But, the literature suggests that the precision and recall for the gained results using single content descriptor is not significant. The main vision of this paper is to categorize and evaluate those algorithms, which were proposed in the interval of last 10 years. In addition, experiment is performed using a hybrid content descriptors methodology that helps to gain the significant results as compared with state-of-art algorithms. The hybrid methodology decreases the error rate and improves the precision and recall for large natural scene images dataset having more than 20 classes.

The walkability approach is essential to ensure the connectivity among space in the urban area. The design should be appropriate, safety, maximize and capable of reaching every inch of the spaces, just by walking. Good connectivity must allow people to walk freely and accessible in many ways. People have great chances to meet each other or having potential outdoor activities without any challenges. This study aims to measure the user perception of the existing spaces in the urban public housing environment that been covered and uncovered with the walkability linkages. The objectives of this study are to identify the existing pedestrian linkages in the study area; to investigate the user perception of the existing walkability system in the study area, and finally to conclude and provide a better solution for better walkability opportunity among residents to access the public park.© 2016.
