Effect of marker location on user detection in omnidirectional images

Omnidirectional images have seen increasing usage in virtual tours to display remote destinations. These applications use markers or landmarks within the images to drive user interaction. Viewers must be able to efficiently locate and interact with markers for a positive user experience that retains immersion. However, the effect of marker positioning at different spatial locations on user performance remains unstudied. This work studies the positioning of visual markers within an omnidirectional image environment at three different elevation ranges. Our results show that markers positioned less than 32 ° from the equator were found significantly faster than markers between 32 ° and 64 °.
