Jumping onto steps is a promising action for creating an instant height movement in VR, but installing physical steps is impractical. We propose PseudoJumpOn, a novel vertical locomotion technique using common VR setup that allows the user to experience virtual step-up jumping motion. This technique is achieved by combining two types of viewpoint-manipulation methods: gain manipulation, which differentiates the ascent and descent height, and peak shifting, which delays the peak timing. Results of a user study showed that the users in most conditions felt positively in terms of reality and naturalness of actually jumping onto steps, even knowing no physical steps existed.
