Analysis on Using Synthesized Singing Techniques in Assistive Interfaces for Visually Impaired to Study Music

Tactile and auditory senses are the basic types of methods that visually impaired people sense the world. Their interaction with assistive technologies also focuses mainly on tactile and auditory interfaces. This research paper discuss about the validity of using most appropriate singing synthesizing techniques as a mediator in assistive technologies specifically built to address their music learning needs engaged with music scores and lyrics. Music scores with notations and lyrics are considered as the main mediators in musical communication channel which lies between a composer and a performer. Visually impaired music lovers have less opportunity to access this main mediator since most of them are in visual format. If we consider a music score, the vocal performer’s melody is married to all the pleasant sound producible in the form of singing. Singing best fits for a format in temporal domain compared to a tactile format in spatial domain. Therefore, conversion of existing visual format to a singing output will be the most appropriate nonlossy transition as proved by the initial research on adaptive music score trainer for visually impaired [1]. In order to extend the paths of this initial research, this study seek on existing singing synthesizing techniques and researches on auditory interfaces

Vehicular Sensor Network and Data Analytics for a Health and Usage Management System

Automated collection of on-vehicle sensor data allows the development of artificial intelligence (AI) techniques for vehicular systems’ diagnostic and prognostic processes to better assess the state-of-health, predict faults and evaluate residual life of ground vehicle systems. One of the vital subsystems, in terms of safety and mission criticality, is the power train, (comprising the engine, transmission, and final drives), which provides the driving torque required for vehicle acceleration. In this paper, a novel health and usage monitoring system (HUMS) architecture is presented, together with dedicated diagnosis/prognosis algorithms that utilize data gathered from a sensor network embedded in an armoured personnel carrier (APC) vehicle. To model the drivetrain, a virtual dynamometer is introduced, which estimates the engine torque output for successive comparison with the measured torque values taken from the engine control unit. This virtual dynamometer is also used in conjunction with other sensed variables to determine the maximum torque output of the engine, which is considered to be the primary indicator of engine health. Regression analysis is performed to capture the effect of certain variables such as engine hours, oil temperature, and coolant temperature on the degradation of maximum engine torque. Degradations in the final drives system were identified using a comparison of the temperature trends between the left-hand and right-hand final drives. This research lays foundations for the development of real-time diagnosis and prognosis functions for an integrated vehicle health management (IVHM) system suitable for safety critical manned and unmanned vehicle applications

Adaptive Music Score Trainer for Visually Impaired in Sri Lanka

This paper is on a research in progress, trying to solve the problem of how to assist visually impaired users in Sri Lanka to visualize and train Eastern music scores (notations) in a way that satisfies their music needs. Several researches have been done in Western music context to address this issue but fewer researches have been done in Eastern music context in this area. In this study, audio format was identified as the most feasible and effective readable format to read music notations for visually impaired. Therefore the research study has been steered to convert visual music notations (of Eastern music in Sri Lanka) into an audio output which gives visually impaired user a real feeling of reading visual notations as it is and assists to train on them. This can be further extended as a tool which assists visually impaired users in music score generation and music composition

Music Training Interface for Visually Impaired through a Novel Approach to Optical Music Recognition

some inherited barriers which limits the humanabilities can be surprisingly win through technology. Thisresearch focuses on defining a more reliable and a controllableinterface for visually impaired people to read and study easternmusic notations which are widely available in printed format.One of another concept behind was that differently-abled peopleshould be assisted in a way which they can proceed interestedtasks in an independent way. The research provide means tocontinue on researching the validity of using a controllableauditory interface instead using Braille music scripts convertedwith the help of 3rd parties. The research further summarizes therequirements aroused by the relevant users, designconsiderations, evaluation results on user feedbacks of proposedinterface
