Smartphone, as a personal device, has been widely used in people's daily life. As a result, it unavoidably contains user's private and sensitive information, such as financial accounts and social contacts. Unfortunately, recent studies have shown that fingerprint of sensors in smartphones can be used for tracking them, which leads to a significant threat to user's privacy. More importantly, speakers...
Guiding and assisting the visually impaired has been a significant problem. Yet, this problem has received insufficient attention. With the pervasion of smartphones, we attempt to utilize their powerful abilities to assist the visually impaired. Existing applications for assisting the visually impaired are mostly obstacle detection, most of which rely on image processing or pattern recognition techniques...
With the wide spread of smartphones, providing contextualized information for mobile environment has been in demand, and many researchers have explored the topic of context awareness based on sensors in smartphones. The state-of-the-art method in this field only uses for input simple data such as location, current time, user activity and provides simple output. Various events that could take place...
Smartphones have transformed the technology landscape and cultural aspects of modern society. Smartphones are equipped with multiple sensors designated for different purposes expanding their application into a wider area. Tasks, which earlier needed a computer are now performed on a smartphone and are used for health care and assisted living applications. Our research focusses on development of a...
Latest smartphones often have more than one microphone in order to perform noise reduction. Although research on speech enhancement is already exploiting this new feature, robust speech recognition is not still benefiting from it. In this paper we propose two feature enhancement methods especially developed for the case of a smartphone with a dual-microphone operating in an adverse acoustic environment...
Location-based services on mobile devices have become a key element in today's wireless and mobile phone infrastructure, which due to their potential for precise personalization offer interesting opportunities for Semantic Computing. However, location information is mostly only available outdoors and current indoor localization schemes are not very accurate. In this paper, we therefore present a novel...
