User Experience and Response Time when using a Four Channel Screen Surround Speaker Setup
Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
Many computers today use large screens that can show a lot of information simultaneously. This information is spread out over the area of the screen which might cause difficulties finding the correct information at the time of interest. To use sound cues along visual cues have long been used in computers, however it has never commercially been used to help the user to find the information on the screen, only to notice the user that there are information on the screen. The most common speaker setup when using computers is to have two speakers at the bottom of the screen, which is where the built in speakers in both laptops and many desktop computers are located. This opens the possibility to position sound in the horizontal direction. It does not, on the other hand, give the opportunity to position sound in the vertical direction.The aim of this study is to try how an alternative speaker setup could help the user to find information on a computer screen quicker and easier. This is accomplished by placing a speaker in each corner of the screen and pan/elevate the sound between the speakers making the sound to be perceived as originated from different locations on the screen. Reaction tests and experience tests were done by clicking dialog boxes on different positions on the screen accompanied by different types of audio playback. The results showed no improved response time. The experience results suggest a slightly improved user experience when using the four channel positioned sound setup, however the results are too unspecific to draw any certain conclusions and further research is suggested.
