A Flexible Input Mapping System for Next-Generation Virtual Reality Controllers

Abstract

This paper proposes an input mapping system that can transform various input signals from next-generation virtual reality devices to suit existing virtual reality content. Existing interactions of virtual reality content are developed based on input values for standardized commercial haptic controllers. This prevents the challenge of new ideas in content. However, controllers that are not compatible with existing virtual reality content have to take significant risks until commercialization. The proposed system allows content developers to map streams of new input devices to standard input events for use in existing content. This allows the reuse of code from existing content, even with new devices, effectively reducing development tasks. Further, it is possible to define a new input method from the perspective of content instead of the sensing results of the input device, allowing for content-specific standardization in content-oriented industries such as games and virtual reality.

Virtual Reality Simulation of High Tibial Osteotomy for Medical Training

“…Furthermore, in case the I/O management module is dependent on the application program, the application may incur latencies during handling device I/O due to processing other tasks. e proposed surgical simulator allows signals to be exchanged between the morphable haptic controller and the application program with IMD [2]. Figure 5 shows the data flow of the morphable haptic controller using the IMD.…”

“…In this study, a VR simulation is proposed to train trainees with high tibial osteotomy, which is one of the orthopedic surgeries. To give a feeling of reality as if users are actually holding various surgical tools used in a high tibial osteotomy, our new type of morphable haptic controller was used [1,2]. It is possible to present various kinaesthetic and tactile senses only by changing the thickness, length, and the center of mass of the controller without using many devices.…”

“…It is possible to present various kinaesthetic and tactile senses only by changing the thickness, length, and the center of mass of the controller without using many devices. To connect the newly developed device to the fabricated VR simulator using general-purpose graphics libraries, an extendable I/O interface was designed and implemented [2].…”
