Human-Computer interaction methodologies applied in the evaluation of haptic digital musical instruments

Recent developments in interactive technologies have seen major changes in the manner in which artists, performers, and creative individuals interact with digital music technology; this is due to the increasing variety of interactive technologies that are readily available today. Digital Musical Instruments (DMIs) present musicians with performance challenges that are unique to this form of computer music. One of the most significant deviations from conventional acoustic musical instruments is the level of physical feedback conveyed by the instrument to the user. Currently, new interfaces for musical expression are not designed to be as physically communicative as acoustic instruments. Specifically, DMIs are often void of haptic feedback and therefore lack the ability to impart important performance information to the user. Moreover, there currently is no standardised way to measure the effect of this lack of physical feedback. Best practice would expect that there should be a set of methods to effectively, repeatedly, and quantifiably evaluate the functionality, usability, and user experience of DMIs. Earlier theoretical and technological applications of haptics have tried to address device performance issues associated with the lack of feedback in DMI designs and it has been argued that the level of haptic feedback presented to a user can significantly affect the user’s overall emotive feeling towards a musical device. The outcome of the investigations contained within this thesis are intended to inform new haptic interface.

Realism and national identity in 'Y Tu Mamá También': an audience perspective

When referring to cinema and its emancipatory potential, realism, like Plato’s pharmakon, has signified both illness and cure, poison and medicine. On the one hand, realism is regarded as the main feature of so-called classical cinema, inherently conservative and thoroughly ideological, its main raison d’être being to reify and make a particular version of the status quo believable and to pass it out as ‘reality’ (Burch, 1990; MacCabe, 1974). On the other, realism has also been interpreted as a quest for truth and social justice, as in the positivist ethos that informs documentary (Zavattini, 1953). Even in the latter sense, however, the extent to which realism has served colonizing ends when used to investigate the ‘truth’ of the Other has also been noted, rendering the form profoundly suspicious (Chow, 2007, p. 150). For realism has been a Western form of representation, one that can be traced back to the invention of perspective in painting and that peaked with the secular worldview brought about by the Enlightenment. And like realism, the nation state too is a product of the Enlightenment, nationalism being, as it were, a secular replacement for the religious - that is enchanted or fantastic - worldview. In this way, realism, cinema and nation are inextricably linked, and equally strained under the current decline of the Enlightenment paradigm. This chapter looks at Y tu Mamá También by Alfonso Cuarón (2001), a highly successful road movie with documentary features, to explore the ways in which realism, cinema and nation interact with each other in the present conditions of ‘globalization’ as experienced in Mexico. The chapter compares and contrasts various interpretations of the role of realism in this film put forward by critics and scholars and other discourses about it circulating in the media with actual ways of audience engagement with it.
