Visual and Interactive Computing Laboratory

The visual and interactive computing laboratory (ViaLab) comprises of three components: A virtual reality laboratory, perception laboratory, and the radio communications laboratory. Examples of activities pursued under the umbrella of ViaLab are shown below followed by an inventory of research equipment and software.

Testbed equipment used for studies of temporal data delivery issues in a TPCAST wireless virtual reality set-up:

An experimental study on the video freeze assessment of TPCAST wireless virtual reality:

Rating test on 360o video quality and quality of experience (QoE) of remote rendering using the TPCAST wireless virtual reality set-up. Rendering is performed remotely at Campus Karlshamn and the test stimuli are viewed on Campus Karlskrona.

Subjective experiments conducted to quantify the relationship between QoE and single, isolated stall durations in interactive remote virtual reality when stalls either freeze the frame in place, or when frames are reprojected by the VR driver.
