Design of an Interactive Spatial Augmented Reality System for Stage Performance Based on UWB Positioning and Wireless Triggering Technology

Abstract

In this research, the authors designed an interactive spatial augmented reality system for stage performance based on the technologies of UWB positioning and Bluetooth® triggering. The position of the actor is obtained through the antenna tag carried by the actor and the signal base station placed on the stage. Special effects can be triggered through the Bluetooth® module according to the actor, and rendered at the relevant location on the screen, which has higher concealment. The system has a higher degree of freedom in practical applications, which can present an interactive spatial augmented reality effect, and therefore provide new possibilities for the application of spatial augmented reality in the stage performance.

Design of a Technology-Based Magic Show System with Virtual User Interfacing to Enhance the Entertainment Effects

“…Designing interactive performance systems requires dynamic and expandable frameworks, capable of adaptively adjusting its architecture according to various performance constraints, such as venue limitations. This adaptability is achieved by integrating new hardware and software modules, enabling the system to expand itself [13][14][15].…”

Outlet Recognition Based on Deep Learning and Sensors for Large-Scale Cable Laying

“…Sensors have been widely used in augmented reality due to their multimodal, flexible, and real-time characteristics. Zhang et al [1] combined UWB (ultra-wideband) positioning with augmented reality, using localization algorithms to locate actors and bring a higher sense of immersion to spatial augmented reality; Wang [2] combined iBeacon indoor location with augmented reality to detect user location and recommend suitable exhibits for more efficient navigation; Ma et al [3] used multi-sensor fusion location technology to track camera positions and achieve an enhanced display of indoor maps. In addition to being applied to augmented reality, sensors are combined with intelligent algorithms for reliable target recognition.…”

Luvi: Lightweight Uwb-Vio Based Relative Positioning for Ar-Iot Applications

“…In particular, ultrawideband (UWB) technology is resurfacing among leading industries and manufacturers, and being exploited for location awareness and security. Several flagship mobile products, from iPhone 11 Pro-and Galaxy Note 20 Ultra, supports UWB communication capabilities, which can be utilized in the future for indoor location-based services such as smarter car keys [1], indoor navigation [2], and various augmented reality(AR) applications [3]. Every smartphone will be equipped with UWB as an essential feature in the near future, complementing other communication technologies such as Bluetooth and Wi-Fi.…”

“…Since UWB technology only measures distance and cannot provide an actual reference point on the indoor environment, it is often used in combination with visual inertial odometry (VIO) in augmented reality (AR) applications [3] and robotics [4,5]. Measurements must be made at multiple points while recording device displacement to estimate relative position as a point on the actual environment.…”
