Muscle-Propelled Force Feedback: accepted at CHI 2013

31 Jan

Our prototype electrically stimulates the user’s arm muscles via the shown electrodes, causing the user to involuntarily tilt the device. As he is countering this force, he perceives force feedback.

A participant from our user studies experiencing the force feedback sensations delivered by our prototype.

Biohacking and Brain Computer interfaces: the future of Human Computer Interaction (video/youtube)


As a discipline, Human Computer Interaction (HCI) has always wandered on the boundaries between art and science, mainly due to its multidisciplinary genealogy, but often because it is a process of envisioning and questioning the future. The ideas of Cyborg, Augmented Humans and Bio-Feedback have been strong research themes for decades in HCI.

However, two currents need to merge in order for us to grasp the “augmented human”: firstly, to sense and understand ourselves is crucial – reading and understanding our bio-signals and secondly, to let ourselves be controlled. My keynote (video here) on the Leonardo Stage revolved around such matters, where art and science naturally meet to discuss how contemporary bodies will sound and look.

Battle of the DJs: an HCI perspective of Traditional, Virtual, Hybrid and Multitouch DJing

16 Apr

To be presented at NIME 2011 (New Interfaces for Musical Expression, Oslo ). The remainder of the program is very interesting, so please feel free to look around here.

What about DJing?

How does it equates within an HCI perspective?

What forms of interaction exist with DJ gear?

How can one classify those interactions/gear?

The following paper addresses these questions, trying to create a framework of through concerning DJ interactions – a very idiosyncratic type of “music interfaces” – and proposes an evaluation of Traditional (analogue turntables, mixers and CD players), Virtual (software), Hybrid (traditional and software in synergy) and Multitouch (virtual and traditional in synergy).

The term multitouch here defines not a categorization but rather an implementation of a touch sensing surface DJing prototype. Explorations among new interfaces for DJing has already been hapenning for at least 10 years, but an evaluation from such perspective (interactions and devices) can aid researchers and developers (as well as DJs) to understand which tools fit in which style.
