Brain-computer interface (BCI) games can satisfy our need for competence by providing us with challenges that we should enjoy tackling. However, many BCI games that claim to provide enjoyable challenges fail to do so. Some common fallacies and pitfalls about BCI games play a role in this failure and in this paper we report on a study that we carried out to empirically investigate them. More spe...

This paper presents a two stage Brain Computer Interface (BCI) keyboard system that consumes Electroencephalography (EEG) signals based on two evoked potential detection methods: P300 and Steady-State Visual Evoked Potential (SSVEP). In order to develop a practical daily use EEG system, signals were captured with a standard low cost Emotiv-EPOC system and processed using OpenViBE platform. Fast...

In this study, International Affective Picture System (IAPS) were used to evoke fear and neutral stimuli using EMOTIV EPOC EEG recognition system (n=15). During the experiments, data recorded Test bench program. To synchronize records, IAPS pictures reflected on screen. A Python script was written in Open Sesame program provide a synchronized flow Input/Output channels of installed virtual seri...

Outdoor Virtual Environments (OVEs) are becoming increasingly popular, as they allow a sense of Presence in places that are inaccessible or protected from human intervention. These Virtual Environments (VEs) need to address physical modalities other than vision and hearing. We analyze the influence of four different physical modalities (vision, hearing, haptics and olfaction) on the sense of pr...

The idea of rearranging generation assets amongst firms to improve competition has once again surfaced in a recent report on improvements to the New Zealand Electricity Market. We show with examples that rearranging assets, either with asset divestiture to a new firm, or asset swaps between existing firms, may actually reduce competition in electricity markets. Our examples emphasize features t...

This paper describes our experiences in building a virtual keyboard implemented using a Brain-Computer Interface (BCI) that interacts with the eMotiv EPOC Neural Headset. The contribution of the work is an alternative input device for those who have a motor disability and are challenged by traditional input devices. The advantages of a virtual keyboard based on BCI are summarized and we describ...

Reduced skeletal muscle function and cognitive performance are common extrapulmonary features in Chronic Obstructive Pulmonary Disease (COPD) but their connection remains unclear. Whether presence or absence of dysfunction COPD patients is linked to a specific phenotype consisting reduced performance, comorbidities nutritional metabolic disturbances needs further investigation. Thirty-seven wit...
