Project jacquard

ABSTRACT
• Project Jacquard is a new Interfacing Technology that makes it possible to
weave touch and gesture interactivity into any textile using standard,
industrial looms.
• Everyday objects such as clothes and furniture can be transformed into
interactive surfaces.
• These interactions can be reconfigured at any time.
• Developers will be able to connect existing apps and services to Jacquard-
enabled clothes .

INTRODUCTION
• R&D by Google ATAP(Advanced Technology and
Projects Group)
• Project team lead by Ivan Poupyrev
• In partnership with Levi Strauss & Co
• Project Jacquard was announced at Google I/O 2015

WHAT IS PROJECT JACQUARD…?
• A platform for embedding sensors & devices in fabrics in ways that seem
natural and comfortable.
• Users can provide input to a mobile phone by touching or stroking the
garment in a designated location.
• Users can receive alerts through vibrations, sounds, or lights in the
garments.
• Novel conductive yarns designed to be woven entirely invisible without
affecting the look and feel of the fabric.
• Can be designed to a variety of colors and textures with designers’ needs.

BACKGROUND & RELATED WORK
• An early exploration of interactivity to clothing using conductive yarns
was Musical Jacket developed in 1998 by Margaret Orth at MIT Media
Lab.
• No significant breakthroughs at attempts to design interactive conductive
yarns for weaving into textiles at industrial scale.
CHALLENGES
Battery requirements are critical.
Electronics must be flexible and able to survive washing, drying, ironing,
and dry cleaning.
Combining Hard Electronics and Soft Textiles.

What’s different in Project Jacquard…?
Conductive yarn can be woven into textiles using standard looms,
inexpensively and at scale.
Woven textile structures withstand harsh and destructive processes
of manufacturing.
Jacquard textiles can withstand home washing, ironing and dry
cleaning cycles.
Electronics & Textiles combined using simple soldering process.
Jacquard electronic system is simple, modular and efficient.

JACQUARD YARN
The core technology for developing interactive textiles.
Jacquard yarn specifications
Conventional look and feel
Multiple colors, thicknesses, and materials
Electrical conductivity
Strength, temperature, chemical resistance
Electronics interconnectivity
Reliability & Safety
Cost and manufacturing at scale
Figure 2. Jacquard yarns are indistinguishable
from normal yarns

JACQUARD YARN ENGINEERING
• Two structural elements – Silk & Conductive Metal Wires.
• The core of the yarn – Several strands of highly conductive thin metal
wires braided with 2 strands of silk.
• This core structure is then over-braided for several reasons.
Figure 3. Jacquard yarn structure.

JACQUARD WEAVING & TEXTILES
• Practically any texture, image, or visual pattern can be woven.
• The textile can be rigid or stretchable, flat or woven with depth,
bumpy, plush, or with ridges.
• The interactivity reside in limited locations defined by the needs of
the application.

CONNECTIVITY TO ELECTRONICS
• The conductive yarn forms a localized, square conductive area, then passes
through the fabric, where it floats.
• Floating Jacquard yarns is connected to electrical interposers by soldering.
• It is relatively trivial to connect the interposer to any other electronic
device.

JACQUARD ELECTRONICS
 The sensing module
has a built-in gesture
recognition capability
self-capacitance principle
 The processing module
sends gesture or touch
location to mobile phone
uses Bluetooth 4.0
 The power module
sleep & wake-up modes
small, modular, efficient

Jacquard - Usability Evaluation
• After 12,000 swipes, gesture recognition rate ->95.12%
• No visible damage to the fabric.

robotic arm scans interactive area with 2.037 N of
pressure.

Conclusion
• Project Jacquard allows weaving interactive textiles at scale.
• It’s a possibility that the current work will inspire research in new forms of
materials and integration of computation into the everyday objects and
environments.
• Brings the vision of invisible seamless computing one step closer to the
reality.
