This series of demos demonstrate our group's recent progress in regards to Brain Computer Interface (BCI) system. Abstract—An electroencephalography (EEG) based Brain Computer Interface (BCI) enables people to communicate with the outside world by interpreting the EEG signals of their brains to interact with intelligent devices such as wheelchairs and robots. More specifically, motor imagery EEG (MI-EEG), which reflects a subject’s active movement intent, has been attracting increasing attention in developing an EEG-based BCI system.

This demo showcases a device-free, real-time posture recognition approach using an array of pure passive RFID tags, and it works via learning how the Received Signal Strength Indicator (RSSI) from the tag array is distributed when a person performs different postures. It can be potentially used in Fall Detection and Ambulatory Monitoring etc. (download)

Some project demos from students of mine
"Are You in a Good Mood or Bad Mood? Sensing Emotions via Your Smart Phone", Master Research Project by Guangyang Qi, 2016.
Today, mental health becomes a serious obsession due to stress work and study environment. It is necessary to use some technology to measure people's mental status. Fortunately, smart phones equipped with built-in power sensors can be utilized as monitoring users' activities and environment information. In this project, a machine learning based application is deployed, aiming at helping people to track their mental status. Now, your smart phone helps you to know are you happy or sad.
"Trust-based Social Recommendation", Master Research Project by Zhen Zhu, 2015.
Traditional social recommendation systems have a major weakness: these recommendation systems can be easily affected or cheated from malicious users who create ad hoc user profiles and provide fake ratings and reviews. In such a situation, the recommendation systems cannot be reliable. For example, astroturfers are hired by some movie companies to distort certain movie’s ratings on IMDB. This project aims at exploring novel ways on how to prevent this situation and provide more trustworthy recommendations by systematically exploiting the multi-layer trust relationships in social media.
"Building Harry Potter's Marauders Map via Internet of Things", Bachelor CS (Advanced) Research Project by Jack Gerrits, 2015
“The Marauder's Map is a magical document that reveals all of Hogwarts School of Witchcraft and Wizardry. Not only does it show every classroom, every hallway, and every corner of the castle, but it also shows every inch of the grounds, as well as all the secret passages that are hidden within its walls and the location of every person in the grounds, portrayed by a dot….—— Harry Potter’s Wiki”
This project aims at developing a Web-based application built upon Internet of Things, through which we will not only know where everyone is but we will also know what they are doing.
"Activity Recognition Using Embedded Sensors in Smartphones", Bachelor CS (Advanced) Research Project by Leon Chea, 2015.
This project explores the process of developing an Android system that utilises the embedded sensors in a smartphone to recognise a number of common human actions and postures (Standing, Sitting, Walking, Lying,...). Smartphones are a widely available commercial device and using it as a basis for this project creates the possibility of future widespread usage and potential applications. The sensors used include the accelerometer, gyroscope and magnetometer, all of which are commonly found in modern smartphones.
"Automatically Recognize Unhealthy Use of Smartphones", Bachelor CS (Advanced) Research Project by Yuchieh (Henry) Yang, 2015.
This project explores an automated, objective and repeatable approach for assessing problematic usage via collecting a wide range of phone usage data from smartphones, identify a number of usage features that are relevant to this assessment, and build detection models automatically detecting problematic use. For example, using phones in the darkness.
