About you
Bio (optional)
The Cosumnes SMART Fire Department concept is focused on providing community risk reduction by leveraging current and near term technological solutions to provide public education and awareness, firefighter mixed reality training and augmented cyber-physical enabled emergency response mitigation. The platform is being designed to meet the mission of the Cosumnes Services District Fire Department (CSDFD), which includes ‘exceeding expectations at all times’ “.

Captain Kirk McKinzie is the project concept designer who brings 29 years as an emergency responder and nearly a decade in 360/3D forensic technology to the idealistic platform construction. His work is focused on saving lives through SMART fire and life safety systems. His vision is to use Virtual, Mixed and Augmented Reality (VR, MRX and AR) to provide public education, fire prevention awareness, first responder training and situational awareness during emergency response. He is involved with collaborative development of 3D remote sensed point clouds, BIM, computational fluid dynamics, gaming platform applications, haptic touch, digital scent, computer vision, coupled with relevant and actionable multi-sensor fusion; for a cyber physical HUD enabled “Iron First Responder”.
Technical Details
Solution overview
The next breakthrough in operational planning, execution, and safety for first responders will come from Location-Based Services (LBS) that assist personnel in possibly chaotic and perilous situations with location and map related information. An inevitable and critical requirement for the applicability of LBS is their integration into any search-and-rescue setting, hence LBS systems must include indoor positioning, navigation and mapping into wearable devices and real-time platforms. To address these needs, CSDFD proposes to 1) Implement a wearable, multi-sensor based, indoor positioning system with state of the art technology capable of precisely tracking and positioning personnel and/or assets in terms of latitude, longitude, altitude, and orientation; and 2) Develop a group-based, mapping framework for real-time, collaborative construction of 3D maps including optimizations for communications limited in throughput, reliability, and latency. The system will use Building Information Modeling (BIM) and will not only connect emergency first responders to those in need of rescue, but will use physics-based fire modeling – Computational Fluid Dynamics (CFD) – that will show SMART users how a fire will propagate. Using CFD, the device will use real time data in earthquakes, floods, active shooter and other emergency situations. In a training scenario, the wearable device in the form or a helmet or goggles will simulate the desired emergency crisis to allow first responders to interact realistically in a virtual reality environment.

The proposed system will provide a number of benefits to public safety organizations (PSO) before, during and after an operation. Indoor positioning will allow the position of all first responders to be tracked, which is needed to improve coordination and safety. The collaborative mapping framework allows units to efficiently construct 3D maps of the environment and provides context for coordination and navigation. Furthermore, the position logs and constructed map can be analyzed after the operation to analyze performance and safety. Both contributions directly relate to the technical area “Location-Based Services (Indoor Positioning, Navigation, and Mapping)” by addressing the indoor positioning and mapping components. Successful LBS for first responders must be accurate, timely, and reliable across the widest possible range of physical environments and communication channels.
The requirements of LBS for first responders will require the development of simultaneous localization and mapping (SLAM). SLAM techniques use vision, range-finding, and/or inertial sensors to track motion of the device and map the environment simultaneously. The advantages of these techniques are that they are accurate, fast, and require no prior knowledge of the environment. Given the challenging requirements of public safety LBS and the unique advantages of SLAM, a potential LBS solution for first responders would incorporate SLAM technology, distributed positioning and mapping, and optimizations for impaired communications.
DIY Recipe Kit
Broadly, the necessary steps to achieve the proposed contributions are to build a test platform that incorporates SLAM technology, develop a group-based mapping framework, optimize information dissemination for impaired communication channels, and perform live test campaigns. The project has a timeline of 12 months. Existing, state-of-the-art hardware and software technologies may be leveraged to quickly prototype the system. SLAM algorithms and range-finding sensors have reached a maturity level where this approach is now possible.
The test platform will use commercial off-the-shelf (COTS) mobile devices with range-finding hardware and SLAM capabilities. An application will be custom-built to interface with the hardware and associated software development kits (SDK) and visualize real-time location and map data in 3D and 2D.
Established networking methodologies will be used to optimize communications on impaired channels. All members need to receive position and map updates from other members, so these communications will be multicast to maximize throughput efficiency. Forward Error Correction (FEC) will be used to combat bit errors common on unreliable wireless channels. Network outages will be addressed by the octree synchronization methods.
In order to evaluate the positioning, mapping framework, and communication optimizations, two tests campaigns will need to be held. Test scenarios should be planned with first responder personnel to mimic deployments and movements of first responders in emergency situations. The first test will specifically evaluate multi-user positioning and mapping. The second test will incorporate impaired communications scenarios to test the optimizations to information dissemination.
As a SMART training device to simulate real life first responder scenarios, the proposed technology will pose absolutely no threat to users. The SMART helmets/goggles will display an emergency scenario digitally on the faceplate of the helmet/goggles that will be correlated to the LBS data. As a SMART in-field device, the proposed technology has the potential to save the lives of civilians and first responders. As development will occur in close conjunction with active fire fighters to ensure system features are relevant to the needs of PSOs, the technology will be user-friendly, comfortable, and effective for everyday use by first responders, which will further increase the safety of the public and emergency personnel.
Realistic Elements - Virtual
Once a mapping platform is developed, the 3-D mapping and sensing technology will be accessible through an application on any SMART device. CSDFD proposes that a 911-GO app will be available for download on any SMART device already available and widely used by the civilian population. Through 911-GO, civilians will be able to scan their homes, which will produce Building Information Modeling (BIM) data that will be uploaded to a secure network that will be accessible to first responders. The BIM data will allow first responders to use LBS to locate victims of fire and other crises. 911-GO will show first responders and civilians the locations of a fire and have the ability to predict the development of such an emergency situation so that PSO’s and civilians alike may take steps to avoid harm. As SMART devices are now widely used, access to this 911-Go app is precisely realistic.
Realistic Elements - Physical
In order to use this technology as a training tool, PSO’s will need to purchase SMART helmets/goggles so that a scenario may be displayed on the “screen.” Although 911-GO will be available on any SMART device capable of downloading an app, in order for a first responder to train in the most realistic setting, a helmet/google screen will be the most effective in creating an interactive environment. For civilian and PSO use in emergency situations, the greatest hindrance to full integration is public education. The public will need to be made aware of the technology and its importance in reducing injury and death in emergency crises. The public will need to be encouraged to scan their home into 911-GO so that the database has up-to-date information to ensure effective use. As with any technological progress, the most important step is education.
Technology Testing
The proposed SMART helmet/goggles will be able to simulate changes in light, weather, noise and physical instability through life-like renderings on the helmet/goggle screen along with synced headphones built into the helmet that will be available for simulated audio and communication with other first responders. The SMART helmet/goggles will have the ability to record video and audio of the training activities of each user. The proposed platform will have the ability to be integrated into other technologies that may be used during a training simulation including many of those listed in the NIST References and Situations: Location-specific identification tools; Sensors; Touch displays; Audio cues; Voice commands/auditory controls; Data analytics and sharing tools; Smart Alerts; Data integration tools; Mapping technologies; Interface layouts; Biofeedback; Haptic Gesture recognition and Smart watches.
