Avaliação da aplicação de técnicas para amenizar efeitos da Cybersickness em um ambiente de realidade virtual

Abstract

Head Mounted Displays (HMDs), used in games and virtual reality applications, can induce symptoms of cybersickness, which impairs users’ experience and immersion. Symptoms include dizziness, loss of balance, headache, dizziness and pallor. Most users of HMDs experience one or more symptoms of cybersickness, which is also a limiting factor for game developers for these environments. Many techniques traditionally developed for games on traditional monitors cannot be applied to virtual reality HMDs. Considering the problem of cybersickness, the objective of this work is to verify the effectiveness of applying techniques to mitigate symptoms of cybersickness in HMDs in virtual reality environments. Two techniques were implemented, rotational blur and tunneling, in a virtual reality environment that induces cybersickness effects in the participants. As implementation support , the Unity 3D graphics engine was used, which is compatible with most of the virtual reality headsets available on the market. Minimizing the effects of cybersickness while using the environment was assessed in a preliminary experiment and using questionnaires. The evaluated techniques proved to be effective, but further study still needs to be conducted.
