Brain-computer interfaces (BCIs) are often evaluated in terms of performance and seldom for usability. However in some application domains, such as entertainment computing, user experience evaluation is vital. User experience evaluation in BCI systems, especially in entertainment applications such as games, can be biased due to the novelty of the interface. However, as the novelty will eventually vanish, what matters is the user experience related to the unique features offered by BCI. Therefore it is a viable approach to compare BCI to other novel modalities, such as a speech or motion recognizer, rather than the traditional mouse and keyboard. In the study that we present in this article, our participants played a computer game with a BCI and an automatic speech recognizer (ASR), and they rated their expectations and experiences for both modalities. Our analysis on subjective ratings revealed that both ASR and BCI were successful in satisfying participants' expectations in general. Participants found speech control easier to learn than BCI control. They indicated that BCI control induced more fatigue than they expected.

The beginning of the 21st century is an exciting time for museums in terms of new, engaging and interactive exhibits. Current technological developments offer museums ideal opportunities to meet the increasing expectations of their visitors, many of whom are the younger generation growing up in the digital age. With a multitude of devices and objects as well as people incorporated into an ever-growing network of interconnected systems, new patterns, forms of interactions and social relations will emerge. In order to engage visitors, museums are adopting new technologies which come with many possibilities, but also have their individual challenges and limitations. Museums should start looking at the unification of many such technologies in order to capture visitor attention, engage visitor interaction and facilitate social activities, since the large quantity of digital input and output capabilities of these technologies are hidden potentials. However, unless specifically designed for, many of these capabilities remain hidden and technologies remain oblivious of each other's features. Making them aware of each other's capabilities opens the channels for new synergy and engaging experiences for museum visitors. This paper proposes a framework which uniquely identifies a community of people, artefacts and devices within the museum environment and provides the means to discover, and make use of the technological properties of each element, treating them as an interacting ecosystem of complex adaptive systems and networks in physical spaces.
