    HemoSmart: A Non-Invasive Device and Mobile App for Anemia Detection
    (John Wiley & Sons, Inc., 2021-04-06) Jayakody, A; Edirisinghe, E. A. G. A; Lokuliyana, S
    The Hemoglobin concentration in human blood is an important substance to health condition determination. With the results which are obtained from Hemoglobin test, a condition which is called as Anemia (a low level of Hemoglobin) can be revealed. Traditionally the Hemoglobin test is done using blood samples which are taken using needles. The non-invasive Hemoglobin level detection system, discussed in this paper, describes a better idea about the hemoglobin concentration in the human blood. The images of the fingertip of the different hemoglobin level patients which is taken using a camera is used to develop the neural network-based algorithm. The pre-mentioned algorithm is used in the developed non-invasive device to display the Hemoglobin level. Before doing the above procedure, an account is created in the mobile app and a questionnaire is given to answer by the patient. Finally, both the results which are obtained from the mobile app and the device are run through a machine learning algorithm to get the final output. According to the final result patient would be able to detect anemia at an early stage.

    Intelligent Vision Impaired Indoor Navigation Using Visible Light Communication
    (Springer, Cham, 2020) Jayakody, A; Murray, I; Hermann, J; Lokuliyana, S; Dunuwila, V
    Recent statistics of the World Health Organization (WHO) indicate that over 253 million of the world’s population to be visually impaired. Most of these individuals use the white cane as an assistive tool or are often accompanied by caretakers or voluntary helpers as indoor navigation is particularly challenging for them. This chapter describes a substitute vision system designed to assist vision impaired individuals through the use of visible light communication and geomagnetism. Furthermore, the use of database optimization increases the speed and efficiency of data retrieval thus reducing system response time. Though navigation systems that support the visual impaired are readily available, there have been no systems that use both visible light communication and geomagnetism capable of providing accurate and secure indoor navigation assistance, which in turn would increase the overall satisfaction of the system users.
