Title: Eyes front! Abstract: How often do your date’s eyes glance down at your chest? Which products do people notice in a supermarket? How long does it take you to read a billboard? Eye trackers are helping researchers around the world answer questions like these. From analysing user experience to developing a new generation of video games, this technology offers a novel way of interacting with machines. People with disabilities, for example, can use them to control computers. A team at the Department of Systems and Control Engineering (University of Malta) is using a research-grade eye-gaze tracker, worth around €40,000, to test technologies they are planning to commercialise soon.

Title: What’s lurking on your lunch? Abstract: Let's be honest: very few of us make our lunch from scratch every single day. Although meal prepping trends are slowly catching on, bags of ready-to- eat salad, dips, and cheeses remain very tempting-especially when they can stop you from consuming last week's lasagne. Such convenient healthy choices mean that we don't need to think as hard about what's going into our lunch box. But is this food-on-the-move culture really as healthy as it seems?

Title: Phase-based SSVEPs for real-time control of a motorised bed Authors: Gauci, Norbert; Falzon, Owen; Camilleri, Tracey A.; Camilleri, Kenneth P. Abstract: Brain-computer interface (BCI) systems have emerged as an augmentative technology that can provide a promising solution for individuals with motor dysfunctions and for the elderly who are experiencing muscle weakness. Steadystate visually evoked potentials (SSVEPs) are widely adopted in BCI systems due to their high speed and accuracy when compared to other BCI paradigms. In this paper, we apply combined magnitude and phase features for class discrimination in a real-time SSVEP-based BCI platform. In the proposed realtime system users gain control of a motorised bed system with seven motion commands and an idle state. Experimental results amongst eight participants demonstrate that the proposed realtime BCI system can successfully discriminate between different SSVEP signals achieving high information transfer rates (ITR) of 82.73 bits/min. The attractive features of the proposed system include noninvasive recording, simple electrode configuration, excellent BCI response and minimal training requirements.

Title: A real-time SSVEP-based brain-computer interface music player application Authors: Zerafa, Rosanne; Camilleri, Tracey A.; Falzon, Owen; Camilleri, Kenneth P. Abstract: A real-time Brain-Computer Interface (BCI) music player based on steady-state visually evoked potentials (SSVEPs) is presented. This asynchronous BCI can distinguish up to six simultaneously occurring stimuli in addition to idle states during which the user does not want to execute a command. Distinguishing between an intended and non-intended control signal is an essential element for the seamless integration of BCIs with other user activities. The user-friendly design of the music player is based on typical smart phone applications integrated with flickering stimuli that evoke SSVEPs. In addition, the BCI requires only one bipolar EEG channel thus having an easy and quick setup time. The tests conducted by five subjects resulted in a mean kappa coefficient of 0.87 using the asynchronous BCI. This high performance demonstrates the potential of using the system as an assistive application for people suffering from motor impairments and even as an entertainment application for healthy users.
