Introduction to AR Systems
The development of Augmented Reality (AR) systems is a fancy task that requires careful consideration of several aspects, including development time, unique elements of AR systems, and power consumption. One solution to reduce development time is through the use of industry-standard frameworks. These frameworks provide a set of pre-defined tools and protocols that might be used to construct AR systems, reducing the effort and time required to develop them from scratch.
Unique Aspects of AR Systems
AR systems have several unique elements that should be considered during development. They require interfacing with cameras and sensors that observe the encircling environment and execute algorithms as needed by the applying and use case. Additionally, AR systems should be able to tracking users’ eyes, determining their gaze, and delivering content to the AR display accordingly. This is often completed through the use of additional cameras that observe the user’s face and implementing an eye-tracking algorithm.
Accelerating Detection and Tracking
The detection and tracking of users’ eyes is usually a computationally intensive task. However, it is feasible to speed up this task using reVISION, a tool that allows the acceleration of machine-learning and image-processing elements. By using reVISION, AR systems can promote efficient use of bandwidth and processing requirements, reducing the computational load and improving overall performance.
Power Consumption in Portable AR Systems
Most AR systems are portable, untethered, and wearable, which creates a singular challenge by way of power consumption. The processing required for AR systems should be implemented inside a power-constrained environment, which might be achieved using the Zynq-7000 SoC and Zynq UltraScale+ MPSoC families. These devices rank in the highest echelon by way of performance per watt and might further reduce power during operation by exercising different options, corresponding to placing processors into standby mode or powering down the programmable logic half of the device.
Efficient Power Solutions
To achieve a really efficient power solution, designers can follow easy design rules, corresponding to making efficient use of hard macros, careful planning of control signals, and considering intelligent clock gating for device regions not currently required. This provides a more power-efficient and responsive single-chip solution in comparison with a CPU or GPU-based approach. A single-chip Zynq-7000 SoC or Zynq UltraScale+ MPSoC solution using reVISION can achieve between 6X and 42X more frames per second per watt with one-fifth the latency in comparison with other GPU-based solutions.
Security Demands in AR Systems
AR applications require a high level of security, especially within the information-assurance (IA) and threat-protection (TP) domains. To address these demands, designers can leverage the Zynq devices’ secure-boot capabilities, which enable the usage of encryption, verification using the advanced encryption standard (AES), keyed-hash message authentication code (HMAC), and RSA public key cryptography algorithm. Additionally, designers can use the built-in Xilinx ADC (XADC) macro to watch supply voltages, currents, and temperatures, and detect any attempts to tamper with the AR system.
Meeting Security Requirements
To meet the safety requirements of AR systems, designers can employ the ARM TrustZone and hypervisors to implement an orthogonal world, where one is secure and might’t be accessed by the opposite. Should a threatening event occur, the Zynq device has protective options starting from logging the try and erasing secure data and stopping the AR system from connecting again to the supporting infrastructure.
Conclusion
In conclusion, the event of AR systems requires careful consideration of several aspects, including development time, unique elements of AR systems, power consumption, and security demands. By using industry-standard frameworks, accelerating detection and tracking, and implementing efficient power solutions, designers can create AR systems that should not only powerful and efficient but in addition secure and reliable. As the demand for AR systems continues to grow, it is crucial to prioritize these aspects to make sure the event of high-quality AR systems that meet the needs of users.
