OutsideMe

Abstract

External self-image is often used as an effective tool to enhance dancing technique, choreography, creativity, and expression. The traditional tools of presenting external image, such as mirrors or videos, are limited in their mobility, perspective, and immediacy. To address the issue, we present OutsideMe, a vision-sync mixed reality system that enables dancers see their body movements as external observers through a headmounted display (HMD) device. This system captures dancer's posture and blends it into scenes from the dancer's original field of view in an interactive frame rate. The dancers can observe themselves without distracting their presence identities. In this research, we develop four work modes for supporting dancer's training, and carry out a feasibility study and a user study. The feedbacks from the participants performing various dancing styles are analyzed and discussed. The preliminary experimental results support our design. Figure 1. OutsideMe concept includes captured body movement and augmented external self-image.

Acquisition of the Width of a Virtual Body through Collision Avoidance Trials

“…Meanwhile, we found that the number of trials needed for the participants to capture their virtual body was not particularly high (10)(11)(12)(13)(14), based on the two graph lines associated with the first and second groups for the avoiding timing in Fig. 13 becoming closer or crossing at approximately those points.…”

“…Martin et al investigated replacing body parts with digitized unnatural objects such as whisks and hammers to understand how humans perceive their body and its operations [10]. In addition, out-of-body experiences, which are a sensation of one's consciousness leaving one's body [11], can be linked to BOI and have received wide attention by not only neuroscientists and philosophers but also computer scientists/engineers [12], [13]. Other related studies revealed that people could experience the full body-swapping illusion [14].…”

“…OutsideMe is an external self-image mixed reality system for dancers. They can observe themselves from the perspective outside their body while they are practicing [13]. Fan et al [23] presented a multi-embodiment interface for ergonomic product design in which additional simulated virtual bodies are superimposed on the user's own body.…”

Investigating the Learning Process of Folk Dances Using Mobile Augmented Reality

“…A large-scale AR mirror for user training is presented where the mirror allows users to see their movements providing them visual feedback [21]. In [22], AR is used to present virtual dancer as an instructor or a dance partner and enables user to see their body movements as an external observer. Clay et al [23] adapted and integrated AR related tools to enhance the emotion involved in cultural performances.…”

Temporal Manipulation Interface of Motion Data for Movement Observation in a Personal Training

“…Wearing a head mounted display (HMD) has been becoming a realistic approach than personal training than past few years because of the development of low-cost and high-performance HMDs for commercial use 1 . There are several studies that have used HMDs as means of enhancing a training in the context of for tai-chi with video see-through HMD [1], as well as ballet [3]. These studies have shown their value as early prototypes and explorations in training with HMDs.…”
