This is my master thesis project in which I started in January and finished until May 2019. Commencing with the exploration of scientific theories included Human-Computer Interaction, Cognitive Ergonomics (a.k.a Cognitive Systems Engineering), Human Interface, Design Principle, and User-centred design. Following the discovered design methods and process, I did UX research on the construction sites, as well as with sound experts. With the very limited of time, I could only design and prototype on mobile application for the user testing, focused the intuitiveness on the interface. There will be a lot of advancement going on in the future, such as implement this sound technology in the infrastructure.
Based on qualitative research, many labourers expressed that their work lives are intense and stressful due to the fast-paced working style. In the meanwhile, due to constant multi-tasking, their ability to focus on tasks and their own safety can be lacking. Listening to music becomes their daily needs in order to relax. However, the noisy work environment can cause them potentially hearing loss, such as tinnitus or any other hearing impaired symptoms. In addition with the extra stress and unnecessary attention deficit, if they don’t protect their hearing correctly. According to the statistic from the Norwegian Hearing Loss Association, in 2020 will be 100 million people become an occupational hearing loss. With Handyman (temporary name), it provides every need for workers' daily work lives and also promotes the importance of hearing health. This system is suggested to be used by an extended audience, such as users who listen to loud music,.
Handyman is a system that aims to protect semi-skilled labourers from noise exposure. It harmonises users’ listening experience which helps users to be less distracted and stressed. This app has a detector and filter users’ acoustic environment, takes out harsh sounds and turns stressful noise into harmonic sound environments. When users are in the face of danger or hearing loss risk, this app will notify users. In the meanwhile, it assists labourers to organise their day-to-day tasks and provides tools they need, maximising their productivity and comfortability, promoting the quality of work life.
The system gives users unlimited control over real-world sound. Simply plug in their existing headphones and listen to anything they normally listen during work hours. With the in-built filter options allow users to enjoy music and relax under any work circumstances, such as picking the right mode at the right place. For example, at the dock, there is a sound filter made for this situation or in the construction site. Users can still hear their co-workers while enjoying music or listening to the radio. There is also a different mode that allows users to choose if they only want to concentrate on music or both music and the sound of their co-workers.
