Background: Frugal innovations are essential in low-resource settings to provide cost-effective medical solutions without compromising functionality. The Arclight is a robust, solar-powered device that functions as both an ophthalmoscope and an otoscope, priced at approximately 12€ in low- and middle-income countries (LMICs).
Objectives: This study evaluates the Arclight's potential as a video otoscope when attached to smartphones, aiming to enhance telemedicine capabilities in ear examinations.
Methods: Twenty otorhinolaryngology (ORL) specialists rated the standalone Arclight as well as its attachment to an iPhone 12 and a Samsung Galaxy A14 for ear examinations at the University Medical Centre in Mainz, Germany.
Results: The standalone Arclight received the highest ratings overall, followed by the Arclight attached to a Samsung Galaxy A14. Attached to the Samsung Galaxy A14, the Arclight demonstrated significantly higher performance regarding ease of focus (p < 0.01), quality of view (p < 0.05), and zoom capabilities (p < 0.05) compared to the iPhone12 attachment. The iPhone12 setup performed lowest in all categories.
Conclusion: The Arclight is an effective, low-cost tool for ear examinations in low-resource settings. While smartphone integration enhances its potential for telemedicine, performance varies depending on the smartphone used. The Samsung Galaxy A14 proved to be a more reliable option for tele-otoscopy than the iPhone 12. Further optimization is needed to improve smartphone integration and address identified limitations, enhancing the Arclight's utility in telemedicine applications.
Level Of Evidence: NA.

Sensor-based gesture recognition on mobile devices is critical to human-computer interaction, enabling intuitive user input for various applications. However, current approaches often rely on server-based retraining whenever new gestures are introduced, incurring substantial energy consumption and latency due to frequent data transmission. To address these limitations, we present the first on-device continual learning framework for gesture recognition.

CRISPR-Cas-based lateral flow assays (LFAs) have emerged as a promising diagnostic tool for ultrasensitive detection of nucleic acids, offering improved speed, simplicity and cost-effectiveness compared to polymerase chain reaction (PCR)-based assays. However, visual interpretation of CRISPR-Cas-based LFA test results is prone to human error, potentially leading to false-positive or false-negative outcomes when analyzing test/control lines. To address this limitation, we have developed two neural network models: one based on a fully convolutional neural network and the other on a lightweight mobile-optimized neural network for automated interpretation of CRISPR-Cas-based LFA test results.
