A system for assisting in microneurosurgical training and for delivering interactive mixed reality surgical experience live was developed and experimented in hospital premises. An interactive experience from the neurosurgical operating theater was presented together with associated medical content on virtual reality eyewear of remote users. Details of the stereoscopic 360‐degree capture, surgery imaging equipment, signal delivery, and display systems are presented, and the presence experience and the visual quality questionnaire results are discussed. The users reported positive scores on the questionnaire on topics related to the user experience achieved in the trial.

Immersive 360° video needs new ways of interaction. We compared three different interaction methods to find out which one of them is the most applicable for controlling 360° video playback. The compared methods were: remote control, pointing with head orientation, and hand gestures. A WebVR-based 360° video player was built for the experiment.

Although linear textual menus are a widely adopted solution in the mobile phone user interfaces, alternatives that would take smaller amount of screen real estate exist, e.g. toolbars and pie menus. Pie menus also provide access to functions with fewer key presses than traditional Options menu but are best suited for expert users. We compared toolbars and pie menus as a way to access most often used functions of a mobile media player. Based on user test results, we selected pie menus for implementation into a prototype and made another user test to see what kind of design considerations are related to pie menus for digital joysticks. The user feedback was positive and six design issues were identified.
