Yippi, my Studio proposal for TEI 2012 has been accepted! I will be running this day long workshop with Stoffel Kuenen, PhD student at UID, and Ali Israr from Disney Research. The Studio program is pretty exciting this year, it’s great to be part of it. Here is the abstract for our Studio:
This studio proposes to tangibly explore the world of haptics to develop a greater understanding and sensitivity to this emerging field. The first part of the studio focuses on general knowledge about haptics, haptic and multimodal perception in humans, and key advances in actuator and sensor technologies to develop haptic interfaces. Numerous demos and testing platforms will be available to relate discussions with real haptic sensations. The second part of the studio aims to explore the various challenges and difficulties in designing haptic interfaces by directly building and sketching in hardware haptic interfaces. Participants will be invited to build their own haptic interfaces from various actuators, sensors and other building blocks. The studio aims to bridge the fields of haptics and design, and investigate various prototyping tools and approaches that can best support haptic design activities.
The Studio is limited to 20 participants and is free for all attendees, so register quick :-)
ShapeShift, electro-active polymer (EAP) explorations, link
ShapeShift is an experiment in future possibilities of architectural materialization. This project explores the potential application of electro-active polymer (EAP) at an architectural scale. EAP offers a new relationship to built space through its unique combination of qualities. It is an ultra-lightweight, flexible material with the ability to change shape without the need for mechanical actuators. As a collaboration between the chair for Computer Aided Architectural Design (ETHZ) and the Swiss Federal Laboratories for Materials Science and Technology (EMPA), ShapeShift bridges gaps between advanced techniques in architectural design/fabrication and material science as well as pushing academic research towards real world applications.
Haptics Technologies: Bringing Touch to Multimedia, book, link
Series: Springer Series on Touch and Haptic Systems, El Saddik, A., Orozco, M., Eid, M., Cha, J. 1st Edition., 2011, XV, 218 p. 87 illus.
This book is different from any other book that has looked at haptics. The authors treat haptics as a new medium rather than just a domain within one of the above areas. They describe human haptic perception and interfaces and present fundamentals in haptic rendering and modeling in virtual environments. Diverse software architectures for standalone and networked haptic systems are explained, and the authors demonstrate the vast application spectrum of this emerging technology along with its accompanying trends. The primary objective is to provide a comprehensive overview and a practical understanding of haptic technologies. An appreciation of the close relationship between the wide range of disciplines that constitute a haptic system is a key principle towards being able to build successful collaborative haptic environments.

Sticky Data device from The Institute for Boundary Interactions, link
The most stimulating thing about being able to sense geo-located data is the thought that you are physically feeling traces of people’s experiences in the same place where they happened. We think this gives an extra sense of connection to a place, even if only for a moment. [text blurb and image from We Make Money Not Art]
Glove to improve sense of touch, from Georgia Tech, link
Previous research has shown that adding an appropriate amount of white noise — a concept called stochastic resonance — can improve sight, hearing, balance control and touch, but the white noise had not been incorporated into a wearable device. The Georgia Tech prototype is believed to be the first wearable stochastic resonance device, attaching to the fingertip to improve the sense of touch.

Braun Lectron System, link, from MOMA exhibition Talk to Me.
Dieter Rams and Jurgen Greubel designed the Braun Lectron System (1967- 69) as a teaching tool for use in schools and universities. It is made up of a large range of little bricks, like dominoes, that magnetically connect to one another. Once the blocks are organized on a conductive plate, they can form a variety of functional circuits. See this link for an expanded text on the Lectron kits. Thanks Stoffel for sharing this from your notes.

RolyPoly enables two individuals to “sense” the presence of each other even though they may be physically apart. This is achieved through the mirrored movements in a pair of RolyPolys. A gentle tap to rock one RolyPoly simultaneously rocks its partner RolyPoly to the same degree. Likewise, a sudden shake and rattle in one instantly produces a corresponding reaction in the other.

Last week, I attended Sketching in Hardware 2011 in Philadelphia (USA) and it was super interesting. I missed last year’s edition, so I was happy to be able to participate in this year’s gathering.
Sketching in Hardware is an annual summit on design and use of physical computing toolkits. The summit invites toolkits developers, educators and makers to discuss about prototyping in the realm of hardware + software electronic toolkits.
I decided to present my thoughts and some insights related to scaling issues in hardware sketching that I’ve been observing while teaching at UID over the last 5 years. I titled my presentation “Extreme Interactions”, knowing it can be interpreted in many ways. In this presentation, extreme means beyond the common, outside of your comfort zone. In typical Physical Computing classes, students learn basic electronics and how to interface hardware with software. The baseline activities often revolve around Arduino, with a few sensors, some LEDs or servos, and maybe a specialized module or shield. What I wanted to convey in my presentation is that the world of physical computing is much larger than that, and intentionally exploring different scales (size, power, number, etc) can be very beneficial for learning. The various orders of magnitude are also nice learning vectors to plan, build and reflect about limitations and prototyping activities.
I received good comments from participants and I will definitely try to evolve my thoughts on these scaling issues. I use the Powers of Ten reference to support the exploration of various scales. Maybe the analogy is not right, but I like the similarity with the physical computing domain and the educational endeavors: humans/designers know mostly about human-scale and common issues, anything larger or smaller is tackle by experts. Exploring new domains, pushing boundaries and learning from problems and failures is intellectually stimulating and rewarding.
The Art & Science of Touch
In this video, artist and jewelry designer Farah Bandookwala uses Haptics (via Cloud 9, a 3D touch-modeling software) to design her works. It is not the first I hear about the Cloud 9 software, I should try it out with my Falcon eventually. [via Ponoko]
Artificial Muscle: Designing for Haptics, link
Kicker Studio, published a small case study about work exploring haptics. After reading the article, I find it a bit superficial. It is mostly about enhancing UX touchscreen products with vibrotactile feedback. The thing I appreciate the most with the write-up is the importance of building prototypes to feel haptics during the design work. As I’ve been finding myself, haptics is best multimodal (haptic + sound effect = believability) and the timing is crucial to get things right.
Immersion’s Haptic Design Guidelines, link
I have been exploring and playing a bit with Immersion’s new SDK for Android called MOTIV. I appreciated the Universal Haptic Layer (UHL) available as a list of 100+ predefined haptic effects. I tried it on my HTC Nexus One, and it is a bit disappointing, it is mostly buzzing differently. I guess some new phone hardwares with LRA or piezo actuators provide enhanced haptic rendering capabilities. Immersion is providing a few guidelines for designing haptic effects, with good insights about timing and considerations for various type of actuators. I’ll definetely continue exploring MOTIV Studio, their development tool to draw and build haptic effects.
Four Stages of Competence
I am trying to dig into a bit of psychology these days to mostly learn about learning processes and learning styles. Only key model that I recently found is the “conscious competence” learning model [wikipedia]. It has four main stages: Unconscious Incompetence, Conscious Incompetence, Conscious Competence and Unconscious Competence. There is often a fifth stage added to the model. The best resource for introducing and explaining it this page at Businessballs.
