 +====Week 39: Music and Motors====
 +//​with:​[[http://​ciid.dk/​education/​people/​faculty/​david-gauthier/​|David Gaultier]] and [[http://​ciid.dk/​research/​people/​jakob-bak/​|Jakob Bak]]//\\
  
 +
 +===Introduction===
 +
 +In this class our focus is on introducing the technology and physics of dynamic tangible interaction. Using “the Hand” as a specific context of interaction,​ students will learn the basic science of motorized force-feedback haptic technologies and learn how to use it in conjunction with sound synthesis.
 +
 +===Content===
 +Haptics research engages with questions of tactile perception and feedback. In recent years, haptics research has produced a variety of promising media interfaces, which are meant to bring together digital information and the sense of touch. ​
 +
 +This domain, however, is rather underdeveloped in terms of didactic material, due in large part to the fact that the devices used to create experimentations are either publicly available or affordable for students to directly engage with. While toolkits for sketching and quickly prototyping haptics interfaces using vibro-tactile devices have been devised in the past, we are proposing to extend this initiative with a focus on simple dynamic force feedback devices with high temporal resolution. ​
 +
 +Using simple and low-cost tool sets that we have developed specifically for engaging interaction designers with the study of haptics, our aim is to advance the quality of haptics research and experimentation in the classroom. Our approach is to provide students with specific and simple servomechanisms that feature high resolution sampling rates (position sensing) while offering high output refresh rates (torque control and sound). ​
 +
 +==Motors & Music Platform==
 +
 +In order to engage students in the design of haptic artifacts, we have devised and constructed a new Arduino-compatible board called “Motors&​Music” which together with dedicated software libraries comprise an experiential platform tailored at introducing haptics and sound synthesis concepts and techniques to designers. ​
 +
 +The hardware platform comprise both a motor controller (H-Bridge) and an audio circuit (digital-to-analog converter and audio amplifier) that are used to output control current and sound, respectively. For the workshop two types of servomechanisms will be introduced. The first is the Plank, repurposed voice-coil motors from old disk drives that have been retrofitted with Hall effect sensors to provide position feedback information to the Motors&​Music boards. The second is motorized slider / potentiometer found in mixing consoles. In combining these elements participants will be able to utilize the software libraries to create embedded, real-time, integrated sound synthesis and dynamically control the force exerted by the aforementioned force-feedback devices.
 +
 +==Motors & Music Topics==
 +
 +(A) Physical Modeling
 +
 +We believe it is important to understand the tactile qualities of everyday objects in order to reproduce their perceptual modes using digital apparatus. We will experiment in modeling phenomena such as spring, oscillation,​ and damping in order to provide a rich tactile experience, which are cognitively grounded. With the introduction of concepts such as force sensing and feedback, we will provide technical design vocabulary to students, which can in turn be used in future research work relating to dynamic tangible interactions. Using both visual design tools and programmatic algorithms to model “force fields”, participants will have a direct hands-on experience of their mathematical models, helping them understand the subtleties of physical and tactile force-feedback modeling. ​
 +
 +(B) Sound Synthesis
 +Having established the basis of force-feedback design, we will next look into the design of audio feedback using real-time sound synthesis techniques. Our aim is to introduce how sound can support the perception of touch. With the introduction of concepts such as tone, pitch, and detuning, participants will be asked to map these sonic features to the ones derived from the aforementioned physical models, fusing tactile feedback and sound synthesis.
 +
 +(C) Haptics Design
 +Moving forward from the technical work, we will conceptualize and derive an understanding on how the combination of haptics and sound may be categorized and employed in tangible interaction contexts. As systems using haptics and sound synthesis may propose new affordances to products, designers need to develop new approaches in the investigation and development of the form, functionality and materiality of novel objects and interfaces.
