Monitoring practices
![Page 12: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/12.jpg)
12
Monitoring practices
• Regular check-ups– Daily, weekly, or routinely rounds– Starting with technology– Ending with traditional instruments or observation
![Page 13: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/13.jpg)
13
Technology-mediated monitoring
• Routine digital sensing– Thermometer: saving animal from losing
temperature–Weather report: when raining, flower can’t secrete
nectar; when too cold, too day, it’s the same.– ORP sensor: to ensure proper function of the ozone
generator – Scale: to make sure the animal is healthy– Soil tests
![Page 14: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/14.jpg)
14
Technology-mediated monitoring
• Occasional digital sensing– Plants grow not properly: pH problem or a nutrient
deficiency– Unusual fish behavior: pH, light or oxygen– The amount of fermented honey: refractometer
with 18% threshold
• Abandoned digital sensing– No sprinkler due to faulty humidity sensing– No testing soil but observing plant growth
![Page 15: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/15.jpg)
15
Traditional or observation-based
• Magnification and counting tools– Beekeeping: monitoring tray with square inch grid– Handmade traps: to catch insects–Magnifying hand lens: to observe the stages of
beneficial larvae on leaves– High-resolution microscope: to check various
parasites of fish
![Page 16: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/16.jpg)
16
Traditional or observation-based
• Monitoring through physical engagement and action– taps plants to let clouds of whitefly to emerge– tip beehive to gauge its weight and infer the
amount of nectar– Stick finger into soil to measure the moist of soil– Scuba dive into tank to monitor fish appearance
and behavior
![Page 17: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/17.jpg)
17
Traditional or observation-based
• Monitoring through ‘naked’ observation– Smell: to check if the ammonia is in the water– Sight: to see what’s germinating can tell the
temperature– Taste: to identify the flower the bees get– Hearing: to know the planting time by hearing the
bird mating calls– Touch: to detect pest by feeling sticky on the
leaves
![Page 18: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/18.jpg)

Types of living indicators
![Page 19: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/19.jpg)

Types of everyday biomarkers
• One-to-one– For the bees, chicken coop smell = deadly bacterial infestation; piping sound
= new queen is ready– Green water = ozone deficiency– Saw dust at the bottom of vine plants = borer pest– Hydrangea color = soil pH value– Accentuated leaf growth = too much nitrogen
• One-to-many– A yellowing “between vein of leaves” = nutrient deficiency or pH imbalance– Blossom end rot in tomatoes = lack of calcium or moisture content– Sliming fish = poor water quality or a parasite– Trembling bees = sprayed or got contaminated by chemical
![Page 20: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/20.jpg)
20
Types of everyday biomarkers
• Ecosystem– Local drought and blooming cycles by observing the
bees– Tracking the balance between pest and beneficial
insects for monitoring the greenhouse– Coral reef bleaching as a response to stress or
disturbance to the system– The endangerment of the Philippine crocodile
suggesting “pollution, habitat loss– Diseases prevailing on unhealthy plants
![Page 21: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/21.jpg)

infestations– Recipes of honey products– Schedules and layouts for crop rotations– Gardening journal– Sharing Mechanisms
• Sharing Mechanisms• Casual conversation, e-mail, facebook, twitter, books, blogs,
radios and speaking to zoo visitors
![Page 23: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/23.jpg)
23
Data collection, sharing and speculation
• Speculation based on data and sharing mechanism– Through discussion and blog to know weather pattern allows
stink bugs to reproduce rapidly– Urban water quality affects the growth of the plants and the
fish due to chlorine, fluoride and other chemicals use for disinfection
– Colony Collapse Disorder (CCD) in honeybees due to the pesticides or genetically modified plants
– Nitrogen soil deficiencies due to chemical sprays on the yards– The endangered Louisiana Pine Snake due to the disappearing
habitat of their food source pocket gopher causing by forest management

DESIGN IMPLICATIONS AND OPPORTUNITIES
• Leveraging non-digital inputs• Designing technologies that teach new ways
of seeing• Enriching practices of data collection and
sharing
![Page 26: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/26.jpg)
26
Leveraging non-digital inputs
• Expanding the UbiComp community’s vision of sensing beyond electronic devices, to include living organisms and traditional tools
• Shift from designing sensing technologies to designing ubiquitous systems that incorporate living organisms and traditional tools along with digital devices, either active or passive
![Page 27: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/27.jpg)
27
New ways of seeing
• Skilled technologies abandoned after participants developed a skill
• Support new ways of seeing or engaging with the environment
• Encourage human awareness, refection and wonderment about our living world
• Embracing low-fidelity signals– Imprecise sensing practices of biomarkers and
traditional tools– With indiscreet input and to embrace ambiguity
![Page 28: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/28.jpg)
28
New ways of seeing
• Peripheral engagement– To know the whole system by observing peripheral
biomarkers
• Scaffolding (鷹架 )– New scaffolding tools that train individuals and groups
to ‘sense’ better and differently– Activity recognition and participatory sensing
appropriates mobile phones as digital sensing devices– sensing as a conjoint practice, tool for community
togetherness
![Page 29: Nurturing Natural Sensors UbiComp 2011 Best Paper Stacey Kuznetsov, William Odom, James Pierce, Eric Paulos Human-Computer Interaction Institute Carnegie.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d135503460f949e6d9d/html5/thumbnails/29.jpg)
29
Data collection and sharing
• Recorded in logs, databases and personal journals through causal conversation, blogs, radio and so on.
• Opportunities for existing and future citizen science applications to incorporate individuals working with living systems
• Community concern and political interest– Collective action around shared issues– Using the scaffolding tools for biomarker data of
everyday life
