Goal: Object detection and spatial orientation using non-human sense. (Echolocation-like)
1) Group of volunteers is instructed to wear HMD and informed that they are only allowed to move and make any sounds.
2) B_BODY scenario 01 is started and volunteers dive in the simulation
3) Volunteers are left alone and let to express themselves without any instructions.
4) After one minute of the experience, volunteers are encouraged to describe what they see, if anything
5) The session is terminated after 2 minutes, however the end is not forced and volunteers are allowed to stay immersed as they like.
- video recording
- measured time required to detect and describe objects
- collection of subjective description of experiences
Goal: Evaluate different prototypes of non-human echolocation based interactions
1) Volunteers is guided through the different scenarios
2) Volunteers describe their experience and provide feedback
- video recording
- collection of description of experiences
- basic experiment participants number: 37
- number of recorded sessions: 12
- number of participants allowing use of video footage: 8
- number of participants unable to reach the goal of the basic experiment: 2
- All of the participants were able to detect and identify objects and the depth of the scene in given time.
- The aesthetic: Majority of volunteers described the visual style as "amazing" or "captivating" as their first impression. However, it seems that even the simplest version of echolocation was received as attractive.
- The ability to recognize objects was increasing with the number of sessions. While some of the volunteers struggled during the first minute, their skill to use simulated echolocation steeply increased once they were able to "see" first objects.
- The motion sickness appeared only in a few cases. However, it completely disappeared with repeated immersions. It appears that we can "un-learn" it.
- Group that participated in the Test 01 couldn’t participate in the same test again, as they “knew” what to look for.
- Noise of the surrounding environment heavily influences personal experience, and alignment of sound and vision becomes hard to achieve.
- Locomotion with sound particles is unusable in noisy environment.
- Some participants were shy to use their voice in public environment.
- Sensory alignments deepen the embodiment and the presence.
- Physical body posture: Despite the not-resent body tracking, most of the participants were using their full bodies in a very relaxed manner: They pointed at objects, some of them pretended flying or dancing.
- Given vocal instruction play a big role in the adaptation process. As the test were progressing, the less information was given, the better was the observable outcome.
