Designing a 3D Navigation System Using Cognitive Factors
TypeCommunications sans actes
This paper focuses on the measurement and the mathematical definition of cognitive parameters of designing a navigation systembased on these parameters. The nausea level due to different velocities of a 3D scene, the user head rotation around Yaw, Roll and Pitch axes, the delay between navigation device stimuli and the 3D display movement are measured. Appropriate mathematical functions are ﬁtted to the measurements. A sickness level is deﬁned as an accumulation of a nausea level due to the velocity and the delay. Assigning an analog control button on the navigation device will help the user to adjust the speed. The records of the test-bed and practical experiments prove the effectiveness of this kind of design. Moreover, due to the parametric design of the system, any maloperation can be readjusted with further inquiries over the speciﬁc applications. In addition, any amendment or modiﬁcation performance can be compared with the parametric criteria.

Improvement of the real-time gesture analysis by a new mother wavelet and the application for the navigation inside a scale-one 3D system MIRZAEI, Mohammad Ali; CHARDONNET, Jean-Rémy; MERIENNE, Frédéric; PERE, Christian (IEEE, 2013)This paper proposes a navigation technique for traveling inside a real-scale 3D model based on human gesture analysis. In the ﬁrst step, a simple threshold is used as a criterion to analyze gestures. In the next step, a ...
