Continuous health monitoring for an infant is crucial for detecting and preventing several diseases. Recent advancement in wearable technology has given rise to the development of wearable infant health monitoring systems (WIHMSs). These systems provide an edge over conventional infant health monitoring systems which are not only bulky and uncomfortable for the infants but are also limited to the clinical settings. This study reviews some state-of-the-art WIHMS, mentions the advantages, limitations and the challenges faced by such systems. This study, for the first time, contributes an appraisal of research prototypes and commercially available systems for WIHMS, which is the need of the day.

Vision plays a paramount role in our everyday life and assists human in almost every walk of life. The people lacking vision sense require assistance to move freely. The inability of unassisted navigation and orientation in outdoor environments is one of the most important constraints for people with visual impairment. Motivated by this problem, we developed a simplified and user friendly navigation system that allows visually impaired pedestrians to reach their desired outdoor location. We designed a Braille keyboard to allow the blind user to input their destination. The proposed system makes use of Google Directions API (Application Program Interface) to generate the right path to a destination. The visually impaired pedestrians have to wear a vibration belt to keep them on the track. The evaluation exposes shortcomings of Google Directions API when used for navigating the visually impaired pedestrians in an outdoor environment.
