Summary: This work develops a system of spherical magnetic tangibles, GaussMarbles,
that exploits the unique affordances of spherical tangibles for interacting
with portable physical constraints. The proposed design of each magnetic sphere
includes a magnetic polyhedron in the center. The magnetic polyhedron provides
bi-polar magnetic fields, which are expanded in equal dihedral angles as robust
features for tracking, allowing an analog Hall-sensor grid to resolve the
near-surface 3D position accurately in real-time. Possible interactions between
the magnetic spheres and portable physical constraints in various levels of
embodiment were explored using several example applications.

Summary: We present GaussRFID, a hybrid RFID and magnetic-field tag sensing system
that supports interactivity when embedded in retrofitted or new physical
objects. The system consists of two major components -- GaussTag, a
magnetic-RFID tag that is combined with a magnetic unit and an RFID tag, and
GaussStage, which is a tag reader that is combined with an analog Hall-sensor
grid and an RFID reader. A GaussStage recognizes the ID, 3D position, and
partial 3D orientation of a GaussTag near the sensing platform, and provides
simple interfaces for involving physical constraints, displays and actuators in
tangible interaction designs. The results of a two-day toy-hacking workshop
reveal that all six groups of 31 participants successfully modified physical
toys to interact with computers using the GaussRFID system.

Summary: The analog Hall-sensor grid, GaussSense, is a thin-form magnetic-field
camera technology for designing expressive occlusion-free, near-surface
tangible interactions on conventional portable displays. The studio will
provide hands-on experiences that combine physical designs and the GaussSense
technology. Through a series of brainstorming and making exercises,
participants will learn how to exploit natural hand and micro interactions
through designing the expressions and affordances of physical objects, and know
how to utilize physical constraints to provide additional kinesthetic awareness
and haptic feedback. The exercises will be including form-giving, electronic
prototyping, and hacking physical toys that are prepared by either the
organizers or participants.

Summary: This work presents GaussStones, a system of shielded magnetic tangibles
design for supporting multi-token interactions on portable displays. Unlike
prior works in sensing magnetic tangibles on portable displays, the proposed
tangible design applies magnetic shielding by using an inexpensive galvanized
steel case, which eliminates interference between magnetic tangibles. An analog
Hall-sensor grid can recognize the identity of each shielded magnetic unit
since each unit generates a magnetic field with a specific intensity
distribution and/or polarization. Combining multiple units as a knob further
allows for resolving additional identities and their orientations. Enabling
these features improves support for applications involving multiple tokens.
Thus, using prevalent portable displays provides generic platforms for tangible
interaction design.

Summary: Interactivity is a unique forum of the ACM CHI Conference that showcases
hands-on demonstrations, novel interactive technologies, and artistic
installations. At CHI 2014, we aimed to create a "one of a CHInd" Interactivity
experience with more than 60 interactive exhibits to highlight the diverse
group of computer scientists, sociologists, designers, psychologists, artists,
and many more that make up the CHI community. Julie Rico Williamson and Steven

Summary: This work describes a novel building block system for tangible interaction
design, GaussBricks, which enables real-time constructive tangible interactions
on portable displays. Given its simplicity, the mechanical design of the
magnetic building blocks facilitates the construction of configurable forms.
The form constructed by the magnetic building blocks, which are connected by
the magnetic joints, allows users to stably manipulate with various elastic
force feedback mechanisms. With an analog Hall-sensor grid mounted to its back,
a portable display determines the geometrical configuration and detects various
user interactions in real time. This work also introduce several methods to
enable shape changing, multi-touch input, and display capabilities in the
construction. The proposed building block system enriches how individuals
interact with the portable displays physically.

Summary: This work presents GaussStarter, a pluggable and tileable analog Hall-sensor
grid module for easy and scalable bread-board prototyping. In terms of
ease-of-use, the graspable units allow users to easily plug them on or remove
them from a breadboard. In terms of scalability, tiling the units on the
breadboard can easily expand the sensing area. A software development kit is
also provided for designing applications based on this hardware module.
