Lineage01
Why a sidewalk
How research on streets, conversation, and everyday learning became the starting point for Digital Sidewalk Lab.
Research retrospectiveRead
Earlier work in education, media, and public data
Projects from 2021–2023 show the data and communication work that preceded the Digital Sidewalk framework.
Published-work retrospectiveRead entry
Buildspace02
The Digital Sidewalk framework
A study of Buildspace connects everyday participation with indirect learning across online and physical settings.
Published researchRead entry
Nights and Weekends: how the seasons worked
The structure of Buildspace gave participants a public deadline and several ways to learn from one another.
Participant-observation and interview retrospectiveRead
Fort Mason: observing a community through its setting
Rooms, informal routes, and public project displays helped make participation visible in the Buildspace fieldwork.
Participant-observation retrospectiveRead
What I built in Erevald
Making and releasing a Mameen album while participating in Buildspace.
Released creative work; retrospectiveRead
When Buildspace closed
The closure changed the setting of the study and raised a question about what participants carried into their next projects.
Research retrospectiveRead
Making the framework explicit
The dissertation defense clarified how I should state the contribution and explain what can be observed.
Dissertation retrospectiveRead
Naming03
Digital Sidewalk Lab, Gravel9, and the StormNet name
A guide to the research unit, the published framework, and the names that appear in older project records.
Naming and organization recordRead entry
Physics04
One cavity, three domains
A January 2026 design explored whether a shared description of boundaries could support acoustic, thermal, and airflow tools.
Modeling proposal; evaluation pendingRead entry
StormNet05
The field-test console
The StormNet prototype brought maps, camera views, sensor readings, and human observations into one research interface.
Prototype and design retrospectiveRead entry
Testing the 0.71 simulation question
A parameter worth investigating, a proposed connection to field data, and an exploratory detector that was set aside.
Exploratory modeling recordRead entry
The Clemson ice-storm field test
Two consumer devices recorded pressure and audio features during a January 2026 storm. Here is the setup, the reported analysis, and the next test.
Field dataset; working analysis; release pendingRead entry
Keeping the rig running through an ice storm
The field conditions behind the Clemson dataset: a phone outside, a tablet inside, and a change of placement during the night.
Fieldwork retrospectiveRead
Method06
What makes a research prototype usable?
The release standard: a person outside the Lab should be able to install the tool, inspect a sample, and repeat a documented analysis.
Public-release planRead entry
Choosing what to measure next
An experimental planning tool compares candidate measurements by the explanations they could distinguish.
Prototype evaluated on synthetic cases in the working recordRead entry
A useful map explains its gaps
The observation schema records where information came from, what it represents, and why it may be unavailable.
Observation-schema designRead entry
From an observation to an explanation
Four record levels help the Lab track how a measurement becomes a signal, a pattern, or a hypothesis.
Research-record frameworkRead entry
Testing the framework in another community
The next research question is which observations from Buildspace remain useful across different settings.
Comparative research protocolRead entry
Building a record that can be replayed
The August prototype separates original evidence from later interpretation and records which components were implemented.
Architecture and prototype accountRead entry
Comparing recordings from different phones
A proposed calibration protocol asks how much device variation can be estimated without a reference microphone at every node.
Calibration proposal; field evaluation pendingRead entry
Open source07
How this journal uses sources
Dates, source records, AI-assisted work, and the distinction between a project account and a reproducible result.
Editorial methodRead entry
The Lab, the map, and Gravel9 Radio
Research that helps people investigate a place—and helps radio tell them what is happening there.
Current direction and development roadmapRead entry
Opening the sensing platform
The planned release separates the collection and observation tools from optional detection engines.
Release package prepared; public links pendingRead entry
