KI/OSK


By Koichi Yoshino, Takatoshi Yoshida, Yo Sasaki, Xiaoyan Shen, Ken Nakagaki and Hiroshi Ishii.

In recent years, the retail industry has become increasingly interested in Information and communications technology (ICT) systems for enriching the shopping experience. Such systems are increasingly being deployed in retail contexts, however common implementation methods are limited due to high costs and large required footprints. Thus it is a challenge for smaller or temporary retail to install such services. In this study, we explore the usage of a load-sensitive board to improve the retail shopping experience specifically in smaller and temporary retail settings. As a case study, we develop and examine KI/OSK, an easy-to-install modular table-top retail application using SCALE, a previously developed load sensing toolkit specifically developed for Farmers Market applications. Our study uses iterative user research including surveys with Farmer's Market managers to assess design requirements, and testing and revising through a field study in a Farmers Market in Tokyo, Japan.

Venous Materials


Venous Materials envisions a new way to design dynamic tangible interactions using fluidic mechanisms. We are inspired by venous structures that are ubiquitous throughout nature and inside the human body. By changing its colors, veins can inform us of internal and external physical conditions. For example, veins in leaves transmit pigments that drive color change which informs us of the leaf’s internal condition, and also which season it is. When we press firmly on a button, the tip of our finger changes its color - this subtle color change can be used as an indicator to inform us of the amount of applied pressure.

While computer chips and electronics usually require rigid and bulky components, Venous Materials is a soft and self contained mechanism that utilizes mechanical activities as its energy source. Through research with microfluidics technology, we developed an approach for designing, simulating and prototyping fluidic interactive sensors that can be embedded in or attached to any object. We propose a wide spectrum of exciting potential applications by integrating Venous Materials in everyday scenarios: Venous Materials embedded in clothing to visualize on-body motion, pressure and balance, and attached to objects, to enrich learning activities, to augment dynamic graphics and to indicate conditions of package delivery and content.

We see Venous Materials as an important paradigm for Human Computer Interactions and as a first step towards the integration of interactive fluidic mechanisms as embedded sensors and tangible user interfaces. The most rewarding aspect of this project for us is that it lays down the ground principles and fertilizer for the growth of additional research within this realm.

KinetiX - Designing Auxetic-inspired Deformable Material Structures


Research paper:

https://www.sciencedirect.com/science/article/pii/S0097849318301006



An auxetic material is a material that exhibits a Negative Poisson’s Ratio (NPR). Unlike conventional materials, when an auxetic material is stretched (or compressed) in one direction, instead of becoming thinner (or thicker), it becomes thicker (or thinner) in perpendicular directions.



This project describes a group of auxetic-inspired material structures that can transform into various shapes upon compression. While the majority of the studies of auxetic materials focus on their mechanical properties and topological variations, our work proposes a parametric design approach that gives auxetic structures the ability to deform beyond shrinking or expanding for the first time. To do so, we see the auxetic structure as a parametric four-bar linkage. We developed four cellular-based material structure units composed of rigid plates and elastic/rotary hinges. Different compositions of these units lead to a variety of tunable shape-changing possibilities, such as uniform scaling, shearing, bending and rotating. By tessellating those transformations together, we can create various higher level transformations for design.

Mediate: A Spatial Tangible Interface for Mixed Reality


By Daniel Fitzgerald and Hiroshi Ishii

2018 CHI Conference on Human Factors in Computing System

Recent Virtual Reality (VR) systems render highly immersive visual experiences, yet currently lack tactile feedback for feeling virtual objects with our hands and bodies. Shape Displays offer solid tangible interaction but have not been integrated with VR or have been restricted to desktop-scale workspaces. This work represents a fusion of mobile robotics, haptic props, and shape-display technology and commercial Virtual Reality to overcome these limitations. We present Mediate, a semi-autonomous mobile shape-display that locally renders 3D physical geometry co-located with room-sized virtual environments as a conceptual step towards large-scale tangible interaction in Virtual Reality. We compare this "dynamic just-in-time mockup" concept to other haptic paradigms and discuss future applications and interaction scenarios.

Programmable Droplets


Biologists in a lab spend, on average, 30-50% of their time manually moving fluids using disposable pipettes. Programmable Droplets are a low-cost lab-on-a-chip designed to make testing cheaper, faster, and more portable for biological sampling. Using electric fields to move, merge, stir, and analyze drops of biological samples, Programmable Droplets can eliminate contamination, human error, and huge magnitudes of hazardous waste.



Programmable Droplets was created by Media Lab researcher Udayan Umapathi.

In the Acoustic Vibration Lab at Lockheed Martin’s Space Systems Company headquarters in Littleton, CO, engineers have begun a series of vibration tests on the astronauts’ display console for Exploration Mission-1.

Pictured here is a mass simulator of the display console mounted with six isolation struts to two shaker tables.

The shaker tables will simulate the harsh environments experienced by the console during different mission events such as liftoff, ascent, abort, landing, and drogue parachute mortar firing.

The data from these tests will be used to evaluate the console’s vibration and movement, as well as the performance of the isolation struts.

Biologic

Learn more about the project by watching the "Making of Biologic" here: https://vimeo.com/142212881

Initiated from MIT Media Lab, BioLogic is our attempt to program living organism and invent responsive and transformable interfaces of the future. Nature has engineered its own actuators, as well as the efficient material composition, geometry and structure to utilize its actuators and achieve functional transformation. Based on the natural phenomenon of hygromorphic transformation, we introduce a specific type of living cells as nanoactuators that react to body temperature and humidity change. The living nanoactuator can be controlled by electrical signal and communicate with the virtual world as well. A digital printing system and design simulation software are developed to assist the design of transformation structure.

Kinetic Blocks

Pin-based shape displays not only give physical form to digital information, they have the inherent ability to accurately move and manipulate objects placed on top of them. In this paper we focus on such object manipulation: we present ideas and techniques that use the underlying shape change to give kinetic ability to otherwise inanimate objects. First, we describe the shape display’s ability to assemble, disassemble, and reassemble structures from simple passive building blocks through stacking, scaffolding, and catapulting. A technical evaluation demonstrates the reliability of the presented techniques. Second, we introduce special kinematic blocks that are actuated and sensed through the underlying pins. These blocks translate vertical pin movements into other degrees of freedom like rotation or horizontal movement. This interplay of the shape display with objects on its surface allows us to render otherwise inaccessible forms, like overhangs, and enables richer input and output.

Real Martians Moment: Not Your Daddy's Dune Buggy



William Allen is a Mechanical Design Engineer working on development of NASA’s Mars 2020 rover mission. Mars 2020 is the next in a very successful evolution of robotic Mars rovers. In fact, NASA is capitalizing on the success of the Curiosity rover – which is currently on Mars – by using its DNA or architecture to design this new rover. The Mars 2020 rover is expected to have one key upgrade: the ability to gather samples and prepare them for a possible return trip to Earth. This will enable NASA to better plan for safe human missions to the Red Planet in the future.
