Muscle-Propelled Force Feedback: accepted at CHI 2013

Muscle-Propelled Force Feedback: accepted at CHI 2013

Video of participants and myself showing Muscle-Propelled Force Feedback (youtube) Force feedback devices resist miniaturization, because they require physical motors and mechanics. We propose mobile force feedback by eliminating motors and instead actuating the user’s muscles using electrical stimulation. Without the motors, we obtain substantially smaller and more energy-efficient devices. Our prototype fits on the back of a mobile […]

Keynote on Biohacking at Campus Party Europe 2012

Keynote on Biohacking at Campus Party Europe 2012

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 […]

Artists & scientists: Push Boundaries! My keynote at Body Controlled #4 / at LEAP Berlin

My keynote at LEAP Berlin, about art and science – focus on how artists and scientists push boundaries! [Photo, courtesy of Peter Kirn] Read the bio/synopsis from the program of Body Controlled here. More will be published on the upcoming issue of the Canadian Journal of Electroacoustics!

Interactive Construction (Constructable) accepted at ACM UIST 2012

Interactive Construction (Constructable) accepted at ACM UIST 2012

Constructable by Stefanie Mueller, Pedro Lopes, and Patrick Baudisch To appear in Proceedings of UIST ’12 (Paper). Constructable is an interactive drafting table that produces precise physical output in every step. Users interact by drafting directly on the workpiece using a hand-held laser pointer. The system tracks the pointer, beautifies its path, and implements its effect by cutting the workpiece […]

#ITS2011: Augmenting Touch Interaction Through Acoustic Sensing

#ITS2011: Augmenting Touch Interaction Through Acoustic Sensing

Pedro Lopes, Ricardo Jota, Joaquim Jorge [Published at ACM ITS 2011, Kobe, Japan / paper] Recognizing how a person actually touches a surface has generated a strong interest within the interactive surfaces community. Although we agree that touch is the main source of information, unless other cues are accounted for, user intention might not be accurately […]

#ACE2011 paper: Hands-on Tabletop LEGO Application

#ACE2011 paper: Hands-on Tabletop LEGO Application

Daniel Mendes, Pedro Lopes and Alfredo Ferreira, ACE 2011.  The recent widespread of multi-touch interactive surfaces make them a privileged entertainment device. Taking advantage of such devices, we present an interactive LEGO application, developed accordingly to an adaptation of building block interactions and gestures for multi-touch tabletops. Our solution (LTouchIt) accounts for bimanual multi-touch input, allowing users […]

SBIM 2011: Combining bimanual and pen-based input for 3D modelling

SBIM 2011: Combining bimanual and pen-based input for 3D modelling

Multitouch enabled surfaces can bring advantages to modelling scenarios, in particular if bimanual and pen input can be combined. In this work, we assess the suitability of multitouch interfaces to 3D sketching tasks. We developed a multitouch enabled version of ShapeShop, whereby bimanual gestures allow users to explore the canvas through camera operations while using a pen […]

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

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

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 […]

Sharing (old) knowledge#2: Starting Multitouch Dev

The following information was written by me one year ago on the Intelligent Multimodal Interfaces course internal forum. Since there are new students in need of fresh info, I reposted it here, make the best of it: Here it goes: multitouch frameworks, possibilities and simulators – all of them open source + cross platform. 1) […]
