Call for Participationin a Hands-on Course on EMS at CHI’16

Recently, Human Computer Interaction researchers have brought more 
immersive and means to actuate the users’ body. This has led to 
developments such as PossessedHand [CHI’11], Pedestrian Cruise Control 
[CHI’15] or Affordance++ [CHI’15]. Come join us in this Course at CHI’16 
and experience EMS.

What will you learn in this course?

In this course we present electrical-muscle stimulation in a hands-on 
experience. We provide a wearable device ready-to-use and medically 
compliant kit (a), which allows quick Wizard-of-Oz prototyping from any 
tablet or smartphone, thus combining the benefits of haptics with 
mobility. We provide mobile app to control easily the wearable device 
remotely. We will further provide hands-on examples of wearable 
prototypes built on android phones, smart-watches and muscle sensing 
devices such as the MYO.

You take home the code and the schematics to reproduce EMS control 
boards, the slides, the paper handouts, and more importantly the 
experience with EMS to share with your students and colleagues.

What do you need to bring?

Nothing, we will provide everything, including EMS device, electrodes, 
EMS control board, smartphones, etc. If you have your own Android phone 
you can bring it too.

Who’s organizing?

Further Reading

Haptic feedback has been a long-standing promise for the interactive 
channel between humans and computers. It allows leveraging other 
faculties such as proprioception instead of using the visual sense, 
which is often overloaded with traditional UIs. Haptic feedback opens 
more channels of perception. It provides a direct way to interface with 
the user’s body, which increases the realism of interaction – as happens 
with force-feedback and tactile stimuli.

However, most haptic technologies have been away from the current trend 
in Human-Computer Interaction (HCI): mobility and wearability. Therefore 
they are bound for lab and special case such as surgical systems. This 
happened because most haptic resist miniaturization, because they 
require physical motors, mechanics and consume hutch amount of 
electricity. Regard to that the costs and form factor are not suitably 
for mobile usage in everyday life.

Researchers have proposed miniaturizing and simplify haptic devices by 
using electrical-muscle stimulation as to actuate the muscles directly, 
rather than actuating through mechanics and hutch apertures. Although 
the technique was first explored in the 60’s and 70’s, it has huge 
implications for HCI as it allows for mobile haptic devices capable of 
driving realistic forces, such as Muscle-Propelled Force Feedback, which 
fits the back of a mobile phone. Furthermore, researchers showed how to 
shrink down a eyes-free I/O haptic device to the size of a wearable 
bracelet, as demonstrated by Pose-IO.

Moreover, this technique has been shown to work not just for 
force-feedback but also to haptic-guidance situations and for more 
realistic interaction in with virtual objects, such as PosessedHand 
which aids in learning a new instrument, feeling virtual objects and 
navigation support. For more realistic interaction with game objects 
Pfeiffer et al. used electrical-muscle stimulation in games for public 
displays. Hence, different objects properties (soft, hard) were 
simulated for interaction with different gestures (touch, grasp, punch) 
with a wearable system.

In this course we provide researchers with a toolkit to experience EMS. 
We expect that the synergies between different researchers will generate 
new interesting applications and ground-breaking ideas around electrical 
muscle stimulation in HCI.
