Subjektiva upplevelser i split-screen

Split-screen innebär att filmduken är uppdelad i flera delar. Uppsatsen behandlarfilmer där subjektiva upplevelser beskrivs med hjälp av split-screen. Det är ett berättande utifrån en karaktär. En subjektiv upplevelse kan vara en dröm, en hallinucation, ett minne, eller förnimmelse. Split-screen har funnits sen filmens begynnelse och haft sina glansdagar på bland annat 1910-talet och 1970-talet.

Åtgärder för att minimera trafikbullers påverkan på ett rekreationsområde

The aim of this inquiry was to investigate the most appropriate measures to reduce noise impacts from road traffic on the Nydala recreational area in Umeå municipality due to the planned re-routing of the E4 motorway to an existing road along this area. The sound environment is an important part in the experience when we are visiting recreational areas. Noise is not only disturbing; the liberty from unwanted sounds also allows us to perceive natural sounds that are a benefit for the cultural experience. Therefore it is important to take actions to protect this well used area from traffic noise. The reasonable options to avoid noise impact in this case are to lower the speed limit, using a noise reducing coating or use noise protection screens and walls.

Perception of human acoustic communication in the domestic dog (Canis familiaris)

For most dog owners today it is natural to use acoustic stimuli such as talking to communicate with their pets. Words are used both to ask the dogs to perform tricks, as well as to hold ?conversations? with the dog. This literature review looks at how dogs perceive human acoustical communication and how this can influence the behaviour of the dog. This information could be used e.g.

Går det att mäta blodtryck med fotopletysmografi och bioakustisk sensor i kombination?

The aim of the work was to investigate the possibility to combine information from PPG and bio-acoustic technology to extract information that is related to the blood pressure. The measurements have been carried out with several different configurations. First the relation between arterial sounds and the PPG-signal was studied. After those measurements with both PPG and the bio- acoustic technique was concluded on people in different positions and after riding a bike. The goal was to vary the blood pressure.

Simulering av filtrerade skärmfärger

This report present a working model for simulation of what happens to colors displayed on screens when they are observed through optical filters. The results of the model can be used to visually, on one screen, simulate another screen with an applied optical filter. The model can also produce CIE color difference values for the simulated screen colors. The model is data driven and requires spectral measurements for at least the screen to be simulated and the physical filters that will be used. The model is divided into three separate modules or steps where each of the modules can be easily replaced by alternative implementations or solutions.

Tuftade ljudabsorbenter ? väggpaneler för rumsliga och akustiska egenskaper

It is a well-known fact that textiles and carpets have benign sound-absorbing properties. It is desirable to have quantified values of these properties ? especially for architects and interior designers. They often need to be able to giveaccount for the acoustic properties of their designs at a relatively early stage and sometimes have strict acoustic classifications imposed upon them by their contractor. A product with documented acoustic properties would aid when prescribing interior elements.The purpose of this thesis is to develop a wall-mounted panel in hand-tufted material ? aesthetically pleasing and versatile but also having documented and quantified acoustic properties.

Akustisk mätning av U-värde

This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions: ? Can U-value theory be combined with acoustic theories? ? Can the coefficient of heat be affirmed trough an acoustic measurement? The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units. The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory. The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.

Research and development for expanding usability of a
multi-touch device

As new ways of using computers are constantly being developed, other ways of interacting are made possible. One of the most desired types of interaction with computers is a touch-screen where the user can actually organize everything simply by using the fingertips. The purpose of this project is to enhance an existing framework with an application that works with a touch-screen device. The application is to be used as a tool for presentational usage. The result is an application where the user by simple means can use a touch-screen to hold a professional presentation.

Äldre och textinmatning En studie om mobiltelefoner ? traditionella, äldreanpassade och ?touch screen?

Mobiltelefoner tar en allt större plats i vårt samhälle och får många fleranvändningsområden, många av dessa beroende av textinmatning. Det är viktigt attalla har möjlighet att nyttja dessa funktioner, men de äldre glöms ibland bort. Detfinns försök till äldremobiltelefoner men de är ofta överdrivet förenklade och/ellerotillräckligt anpassade för deras behov. Den växande ?touch screen?-tekniken ger nyamöjligheter till hur man designar en mobiltelefon.

Välj, kontrollera och dela: : en sekundär skärmupplevelse

Detta examensarbete har varit att ta fram ett koncept för ett second-screenlager till företaget Headwebs filmuthyrningstjänst. Denna rapport visar på hur tre second-screenfunktioner kan appliceras i en video on demand-tjänst. De tre funktionerna som applicerades var att som användare via sin second-screen välja på vilken enhet man vill se sin film, kontrollera filmens playbackkontroller och välja ut små filmklipp från filmen och dela dessa på sociala medier.Resultatet blev ett lo-fi-prototyp som visar hur de tre funktionerna kan appliceras på Headwebs iPadtjänst och listar för- och nackdelar med de olika konceptet..

Akustiskt åtgärdsprojekt av en rockmusikklubb där live-musik spelas. Vad kan en audionom bidra med?

Introduction: The number of hearing impairments in Sweden is increasing. The largest increase is seen in ages 25-44. There are reasons to believe that these impairments are noise induced. Leisure time noise is not controlled in the same manner that industrial noise is. An ongoing conflict between city council officials and rock club owners, musicians and music event organizers about sound levels at smaller live music clubs exceeding the national sound level restrictions created the need for an acoustic intervention project.

Second screen - För Tv-serier

Today it is not unusual to use a secondary screen to accompany a primary screen. The possibility to integrate these two in the form of an application for the secondary screen have long been possible but have not been developed to full potential. This thesis aims to study the use of the extra information and functions this type of application would make possible and how this type of application could be used.For this study a prototype-application including a real time newsfeed and a static menu for a specific episode of a Tv-series was created based on the information collected in an online survey. The application was tested on a number of people who got to evaluate the experience in short interviews and were given the possibility to recommend changes in the application.The result after the study showed the people where torn about what kind of information would best fit the application but showed over all that a dynamic newsfeed with information continuously updated with the episode where most appreciated. The problem with the difference in interest around the categories would be solved first and foremost by the application being configurable so that every single user has the possibility to choose which kind of information to be updated in the newsfeed.

Basenhetskoncept för projektordukar

Our thesis is conducted in collaboration with Draper Europe AB in Halmstad.The goal of the project has been to construct a baseline concept for the instaling of aprojector screen. Draper Europe AB, in the curent situation, have several kinds of fabrics and designs on their sceens and the cases they are in. Today if you select a screen you can´t chose the design and function of the sceens case.The arrangement of the components inside the cases was to be constructed so the assembler simply could move them to different cases. To make it even easier for the assembler and to save time, the desire of less component was mentioned. Another problem that needed to be solved was the mounting of the projectionscreen at the customer place.

Kommunikation mellan två medium

The aim of this project is to find a concept solution for a wireless transmitting system, installed to transmit data from a hydrophone of the ocean floor down by a wave power generator to the office on shore. The project is a literature review in which previous observations and tests are analyzed and put together to find a solution. The result was a comprehensive solution that includes an acoustic modem to transfer captured information from the bottom to the surface, wirelessly through the water. The information is then sent fron the surface on radio waves through the GSM network to the office on land. Between under and over water there are components to convert information between acoustic waves and radio waves, but also various types of modulation, such as amplitude and frequency modulation is required..
