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.

Setup of a participant with head-mounted display and biosensors in standing and seated viewing for a subjective test campaign about 360^o video quality assessment:

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 360^o 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.

Demo showing VR game experiment evaluating player performance and experience while using different interactions techniques, i.e. HTC Vive Controller and Leap Motion Sensor:
