outline

§ internet of devices and web of things

§ phenotropic communication

§ visual codes

§ generalized pattern recognition

§ consequences for M2M networks and example use cases



successive extensions of the reach of networks

§ network host servers

§ personal computers

§ mobiles

§ IP-aware embedded appliances§ connected through wireless or wireline LAN

§ non-IP devices that get attached though "capillary" networks§ radio PAN (Zigbee, etc)§ power line§ point to point attachment (RS232, etc)

§ passive things that get sensed through "devices"§ virtual one-way network attachment§ virtual "web of things" overlaid on the network of devices§ by analogy with the web as an overlay on the original internet

towards the "web of things"

web of things

when networks get physical…§ a qualitative leap, more than a new quantitative extension of their reach

§ taken up very differently in 2 main domains :

§ M2M & internet of things (àsupply chain management, asset tracking, etc)• bringing physical things into the digital realmð making the analog word more digital!

§ human interfaces (àambient, tangible, contextual, implicit, disappearing…)• enlarged & enriched, grounded in the physical environmentð making the digital word more analog, and more…human

phenotropic communication a throwback to analog network interfaces?

protocol-based

§ serial communication over wire§ syntactic language parsing§ predefined & shared

alphabet & syntax§ symbolic, semantic gap§ multilayered representations§ digital§ exact matching required§ brittle§ added redundancy required for

error protection

phenotropic

§ parallel communication by way of surfaces§ pattern recognition§ patterns that may be learnt and need not

be "known" beforehand§ iconic, no semantic gap§ single layer representation§ analog§ approximate matching possible§ robust§ built-in redundancy

§ coinage and concept originally propounded by VR pioneer Jaron Lanier as an "alternative" to protocol-based communication

§ idea could apply to network interfaces or to communication between modules in a large software system


visual codesbridging phenotropic and syntactic communication

§ optical parallel communication, by way of surfaces

§ not phenotropic communication, because discrete and based on shared predefined symbology

§ advantages over RFID/NFC and other electronic tags§ still an order of magnitude lower cost than tags§ printable on anything (paper, cloth, wood, metal) with different technologies (ink, dye, etching, etc…)§ cameras more generalized than RFID readers

• possible use of cameraphones as well as "environmental" cameras§ possibility to compute relative position, or even (with 2D codes) relative orientation§ explicit interaction only § less security concerns than short range network protocols (e.g. bluesnarfing)

• but may trigger WAN) connexion anyway§ already widely adopted (at least for EAN-13/GS-1 bar codes and QR codes)

§ application domains§ identification and traceability

• inventory management § authentication and counterfeit prevention§ "hardlinking" a.k.a "hyperlinking with the physical world"§ physical browsing, mobile augmented reality

• by pointing• by proximity

§ tangible interfaces with direct manipulation of passive physical objects



2D visual codes

surfeit of competing formats …

§ ISO standards

§ QR codes (JIS X 0510:2004, ISO/IEC 18004)§ DataMatrix (ISO/IEC16022)

• flashcode (used by french mobile operators)• semacode

§ maxicode (ISO/IEC 16023)§ other public domain codes

§ aztec code§ shotcode

§ other solutions (proprietary)

§ Sony cybercode


linear visual codes

§ one dominant standard

§ EAN-13 (superset of UPC-12 used in the US and Canada)

§ alternative solutions

§ alphacodes (barcode-like font for unicode charaters)§ extensible, but requires sequential parsing



color codes

Microsoft high capacity color barcode


multimodal "recognition" of passive physical things

§ models already used in human interfaces§ ambient intelligence/ambient assistance interfaces where the user is not

required to wear or carry a transmitter device to be identified§ visual monomodal object recognition

§ shape recognition§ texture recognition§ color recognition§ recognition of dynamic visual motion patterns § meta-recognition of different codes§ classifying object based on visual code without "knowing" the code

§ recognition based on multiple modalities§ location + shape/texture/color

• absolute cartesian location• relative location

§ weight + shape/texture/color§ acceleration+shape/texture/color



benefits of phenotropic communication for M2M

§ a possibility to enroll in the network objects that

§ are not pre-registered in a "well-known" identification system§ have only a transient use for a M2M network/service

§ a possible way to create "bridges" between non-interoperable networks/systems

§ no shared protocol§ no initial configuration§ no network bootstrap necessary

§ a more robust and scalable way to connect sub-systems that should remain causally isolated

§ avoid side effects§ limit security hazards§ limit potential threats to privacy


phenotropic network directory

§ possible extension/augmentation of existing network directories

§ inspiration from CBIR or location-based network directories

§ upon discovery, assign local provisional identification to each "recognized" object

§ directory may be queried/retrieved associatively using attributes used for "recognition", possibly in combination§ shape§ texture§ color§ location

§ semantic matching could be provided

§ different directories could possibly reconcile their records associatively§ directory 1 has registered "object with cubic shape on the table"§ directory 2 has object with approximately same shape at approximately same

location a the same time : it could be the same…



example applications in home environments

§ identification of objects for tracking, inventory

§ tangible interfaces§ non-multiplexed control devices§ activation of actions that are iconically associated with objects§ physically extended drag and drop of objects ( extension of direct manipulation in GUIs)

§ augmented reality§ retrieve information that is directly linked with object§ attach information to objects

• objects can be "actuated" by combined camera-projector system

§ provide feedback on behavior of M2M home automation system

§ requirements§ full-fledged ambient intelligence "smart space" infrastructure

• distributed sensors ("environmental" cameras and other) • distributed actuators (projectors, displays, etc)

§ same infrastructure may be shared between different applications§ ambient communication§ ambient assisted living, e-health, remote care§ home automation§ energy efficiency
