▶ Title : Listening to Sounds to Introduce a New Class of Smart Mobile Applications
▶ Abstract :In our daily lives, various kinds of sounds are produced from people themselves, computing devices, and surroundings. These sounds have plenty of information including when, where and what happened and eventually lead to the emergence of a new class of smart mobile applications. Two interesting examples are introduced through this talk. One is to turn any surface into a touch interface by listening to sounds. When a user taps a surface, an impact sound, called a touchsound, is produced. We can capture it using the built-in microphones of mobile devices and pinpoint the tapping location by analyzing the propagation pattern of the touchsound. Another work is to leverage sounds as a side channel for mobile payment services. When using magnetic induction-based communication technologies, such as NFC (Near-Field Communication) and MST (Magnetic Secure Transmission), some parts of smartphones are slightly deformed and emit sounds. We reveal that these sounds contain sensitive information and can introduce a new security threat for mobile device users.
