ProjectsEmbodied Cognition and Music Interaction Design![]() In domains such as music, technical understanding of the parameters, processes and interactions involved in defining and analysing the structure of artifacts is often restricted to domain experts. Consequently, music software is often difficult to use for those without such specialised knowledge. The present work explores how the latter problem might be addressed by drawing explicitly on domain–specific conceptual metaphors in the design of user interfaces. Using Embodied Cognition to improve Music Interaction Design (Katie Wilkie, Simon Holland, Paul Mulholland) Song Walker Harmony Space![]() The system is suitable for use by 2-4 players simultaneously, with roles and functions being distributed among the players. (Simon Holland, Anders Bouwer, Mat Dalgleish) Whole Body Harmony Space![]() Our working hypothesis is that providing tactile guidance around Harmony Space will improve musicians’ knowledge of larger scale harmonic elements such as chord progressions and thereby improve their improvisation skills. An open research question we are investigating is whether full-body exploration of Harmony Space, for example moving around a large floor projection, brings any benefits over using a mouse and keyboard to interact with Harmony Space on a computer monitor. (Simon Holland) Exploring computational models of rhythm perception![]() We are testing computational rhythm perception models (including Ed Large’s non-linear neural resonance model) with rhythms containing two different pulses—such as three against four rhythms found in African-derived music. This allows us to test the performance of the model against human empirical data - e.g. tapping to polyrhythms. In order to better test the model, we have carried out new empirical tests of human behaviour. Exploring computational models of rhythm perception (Vassilis Angelis, Simon Holland, Martin Clayton, Paul Upton) Neurophony![]() (Fabien Leon, Eduardo Miranda, Simon Holland) The Haptic Drum KitThe Haptic Drum Kit consists of four computer-controlled vibrotactile devices, one attached to each wrist and ankle, that generate pulses to help a drummer play rhythmic patterns.![]() One aim is to foster rhythm skills and multi-limb coordination. Another aim is to systematically develop skills in recognizing, identifying, memorizing, analyzing, reproducing and composing monophonic and polyphonic rhythms. A pilot study compared the efficacy of audio and haptic guidance for learning to play polyphonic drum patterns of varying complexity. Although novice drummers can learn intricate drum patterns using haptic guidance alone, the study found that most subjects prefer a combination of audio and haptic signals. The Haptic Drum kit appears to have possible applications for sufferers from Parkinsons and patients in need of multi-limb rehabilitation. We are exploring possible research partnerships to explore such applications.The Haptic Drumkit research, including work on the Haptic Ipod is being carried out in collaboration with the Music Computing Lab, expert musicologists, drummers and music educators. (Simon Holland, Anders Bouwer, Mat Dalgleish) The Haptic BraceletsThe Haptic Bracelets are prototype self-contained wireless bracelets for wrists and ankles, with built-in accelerometers, vibrotactiles and processors.![]() They can work by themselves, in networked synchronised groups, or with smart phones, tablets or computers. The Haptic Bracelets are designed to be worn four at once, one on each wrist and one on each ankle, although any number from one to four may be usefully worn. A pair on ankles or wrists has a rich range of uses. The Haptic Bracelets are interactive devices for both input and output, enabling communication, processing, analysis and logging. They can be used for local or remote tactile communication between two or more wearers. Musical applications include

In general, users find this kind of process hard to manage. At the same time, existing UI architectures are not well suited to supporting such activities. It is proposed that a good basis for addressing these and related problems in a principled, scaleable way is the principle of Direct Combination (DC). Both analytical arguments and preliminary empirical evidence suggests that DC can reduce the amount of search required by the user and can offer interactions which are faster, less frustrating, and impose less mental load on the user. Direct Combination makes it easy for individuals and organisations to publish and adapt new services, and to create viewpoints to facilitate different ecologies of activities.Completed ProjectsThe E-sense ProjectThe E-sense Project was funded by an AHRC speculative research grant. In this interdisciplinary research, philosophy and art combined with various flavours of computing: ubiquitous; wearable; and physical.The project involved a range of sensory augmentation devices including the Music Jacket, The Haptic Drum Kit and Song Walker Harmony Space.New User Interfaces for Musical Timbre ProjectThe user interface of most synthesisers tends to be expressed in system (i.e. engineering) terminology, obliging the user to become fluent with the synthesis method employed. This causes problems for many users.The New User Interfaces for Musical Timbre Design Project involves the design, implementation , and evaluation of a prototype of a new kind of user interface for controlling musical timbre that addresses this problem in a principled way. (Allan Seago, Simon Holland, Paul Mulholland)Aspect-Orientated Music RepresentationThis project devised, and now continues to refine and investigate, ways in which Aspect Oriented Programming (AOP) and Multi-Dimensional Separation of Concerns (MDSOC) approaches can be applied to the organization of musical materials for the purposes of music composition and musical analysis. (Patrick Hill, Simon Holland, Robin Laney)Spatial Audio NavigationThe Music Computing Lab has a strong interest in Audio Computing, particularly Spatial Audio. This project was was the first paper to apply spatial audio to navigation for freely mobile sighted users, using a minimal attention approach Spatial Audio NavigationPlanC: A constraint–based musical plannerPlanC was an early musical constraint system, but remains uniquely well-suited for manipulating some aspects of tonal harmony. While most musical constraint systems work with descriptions of musical materials such as individual notes and chords; PlanC draws power from a representation called Harmony Space that encodes high level information about tonal harmony in a three dimensional spatial form as shapes, paths, home locations, forbidden areas and trajectories.
