Many thanks to the organisers and attendees at EuroHaptics 2016. I had a great time at all the workshops and thoroughly enjoyed presenting to the delegates of the Musical haptics: use and relevance of haptic feedback in musical practice workshop. A few pictures from the day can be seen here and my presentation abstract can be seen below.
Quantifying The Effects of Haptic Feedback on DMI Functionality, Usability, and User Experience.
Interactions with acoustic musical instruments require musicians to be fully aware of how the instrument is reacting to their gestures in real-time. This is achieved by the musician’s awareness of instrument feedback. Arguably, the most important aspect of acoustic instrument feedback is delivered in the form of auditory responses and haptic feedback. In many virtual or digital instruments, this closed feedback loop is not present. Therefore, musicians are forced to rely on fewer of their senses to gauge the effect of their interaction upon the device they are using. In haptically enabled DMIs this is no longer an issue as feedback can be simulated via the inclusion of specific actuators and transducers in the device design process. With the separation of these elements, we are now able to explore the individual effects of each haptic element upon a user’s perception of functionality, usability, and the overall user’s experience. To achieve this, it has been observed that conventional HCI techniques can be applied in DMI analysis. However, these techniques are themselves restrictive in their application to creative endeavours. In this workshop, questions will be raised relating to the different analysis techniques that can be applied in a device analysis along with the possibility of quantifying the various aspects of devices that are used to create music with. It is hoped that through the discussion of device evaluation techniques applied in other areas of digital technology, validated evaluation practices for haptic DMI devices may be formulated and a formal measure of effects of haptic feedback in this area can be achieved.
