For neurofeedback to be integrated in society, there is a need for In this paper we discuss our vision on future neurofeedback neurofeedback to be accepted. However, another problem might therapy. We analyze problems of the current situation and debate be that neurofeedback therapy is based on a ‘mind over matter’ for a change in focus towards a vision in which neurofeedback perspective, implying that not only the physical and mental therapy will ultimately be as easy as taking an aspirin. wellbeing are interconnected [3, 5] but also that the physical Furthermore we argue for a gaming approach as training, for wellbeing can actually be a result of the mental one. Although this separation between neurofeedback therapy and gaming has statement has been proven in various studies [3], people may become noticeably smaller after recent development in brain experience problems with acceptance.

However, if it is such a promising concept, why hasn’t this therapy been adopted by the general public and health companies yet? 2. REVIEW
The results of research in the field of neurofeedback seem very promising, but various aspects like discrepancy in society focus, general acceptance and practical issues (time and money) form Figure 1. ElectroCaps [1]

Besides the extensive preparation, these sessions take place at a In present day society, people only consult a doctor when clinic, therefore waiting time and obviously travelling time should experiencing physical complaints. In other words: the focus is too be counted as well. Besides the time aspect, neurofeedback much on the physical aspect of health and on curing the therapy is very expensive and not refunded by health insurances. symptoms. In contrast, the main focus of neurofeedback is on mental issues, e.g. concentration or sleeping disorders and on The identified issues, varying from practical to emotional, might fighting the cause of these disorders, rather than the symptoms. all slow down the development of neurofeedback therapy and its The gap between the health focus of society and neurofeedback therapy is noticeable, which may be one of the reasons that neurofeedback is not applied to its full potential yet.

Furthermore we emphasize the importance of intrinsic motivation (gaming) [9] in Our second suggestion is that a user should be able to conduct a therapy session independently. This implies the need to be able to As applied for health-related training systems, current aims of easily locate the necessary contact-points and applying the sensors. It can be assumed that most of the households already have a computer which can calculate sensor input and provide feedback. This means that in principle, only an EEG measurement - training to alleviate attention and hyperactivity disorders, e.g. device and a software package needs to be applied, which would greatly reduce costs. As a final demand, the training software - training for specific sports such as rowing, cycling etc.; should be easy to operate and perhaps even more important: the software should be intrinsically motivating (playful). - training for relaxation and meditation to cope with mental Based on observations, the following assumptions are formulated, which could be advisable to keep in mind when designing for - training muscular tonicity recovery for cardiovascular playful neurofeedback training sessions: - A1: that it is helpful to give the user rewards based on - training and eating schemes to maintain proper weight or - A2: that it is helpful to simulate elements from an assumed Aims described above, include therapies applied in the medical area, focusing on people with mental disorders.

This However, before neurofeedback training is accepted, there’s a would imply that before society can exploit the various need to cope with multiple challenges neurofeedback is facing, for opportunities of neurofeedback training, such as improving example the practical issues described before. Neurofeedback personal capabilities, people need to be made aware of the therapy currently involves a lot of time, money and other practical possibility called neurofeedback training. For this to be reached, issues which can obstruct the acceptance of neurofeedback we should realize that neurofeedback therapy (as applied at the therapy. We suggest a world in which neurofeedback training is as moment) is the frontier of neurofeedback training. Early adopters like athletes and people with mental disorders presumably have a bigger drive to look further, which resulted into neurofeedback To realise this vision, we suggest home-use should be enabled. therapy. More might follow and neurofeedback could become For this to happen, first of all the involvement of a medical expert more and more accepted when positive media attention keeps on should be decreased (e.g. only for guidance in defining the goals going. Furthermore, part of this acceptance probably has to be and keeping an eye on the progress). Of course, it is still strongly achieved by means of scientific proof, especially regarding the Aart, J. v., Klaver, E., Bartneck, C., Feijs, L., & Peters, P. (2007).

We also propose to enable neurofeedback intrinsic motivation. In general, we propose to make training controllable by the user in home context, which could be neurofeedback training more accessible by designing single-user achieved by designing products according to specific user products for the home environment and thereby achieving our requirements. These requirements are based on the aim of idea of using neurofeedback to its full potential. Furthermore we shortening and simplifying the training methodology and would argue the use of gaming as motivational tool and to support society adopting neurofeedback training. 6. ACKNOWLEDGMENTS
