Every Move You Make: Visualizing Near-Future Motion Under Delay for Telerobotics

Delays in direct teleoperation decouple operator input from robot feedback. We frame this not as a unitary problem but as three facets of operator uncertainty: (1) communication, when commands take effect, (2) trajectory, how inputs map to motion, and (3) environmental, how external factors alter outcomes. We external…

Unit-Less Measurements with StoryStick++: Rethinking Measurement as Interactive Processes

Dimensional measurement remains one of the most error-prone activities in making, engineering, and construction, despite the technical precision of modern instruments. Errors frequently arise not from the tools themselves, but from usability challenges: correct alignment of tools, interpreting numeric values, and tran…

Designing Instructions using Self-Determination Theory to Improve Motivation and Engagement for Learning Craft

Recent HCI research has shown significant interest in investigating digital working instructions for guiding novices to perform manual tasks. While performance enhancement has been a primary focus, it is increasingly recognized that technology's impact extends beyond objective metrics. Trainee motivation and engagemen…

CircuitGlue: A Software Configurable Converter for Interconnecting Multiple Heterogeneous Electronic Components

"We present CircuitGlue, an electronic converter board that allows heterogeneous electronic components to be readily interconnected. Electronic components are plugged into an eight-pin programmable header on the board, and the assignment of each pin in the header is configured in software. CircuitGlue supports a varie…

Measurement Patterns: User-Oriented Strategies for Dealing with Measurements and Dimensions in Making Processes

The majority of errors in making processes can be tracked back to errors in dimensional specifications. While technical aspects of measurement, such as precision and speed have been extensively studied in metrology, the user aspects of measurement received significantly less attention. While little research exists tha…

AirLogic: Embedding Pneumatic Computation and I/O in 3D Models to Fabricate Electronics-Free Interactive Objects

Researchers have developed various tools and techniques towards the vision of on-demand fabrication of custom, interactive devices. Recent work has 3D-printed artefacts like speakers, electromagnetic actuators, and hydraulic robots. However, these are non-trivial to instantiate as they require post-fabrication mechani…

LamiFold: Fabricating Objects with Integrated Mechanisms Using a Laser cutter Lamination Workflow

We present LamiFold, a novel design and fabrication workflow for making functional mechanical objects using a laser cutter. Objects fabricated with LamiFold embed advanced rotary, linear, and chained mechanisms, including linkages that support fine-tuning and locking position. Laser cutting such mechanisms without Lam…

AirTouch: 3D-printed Touch-Sensitive Objects Using Pneumatic Sensing

3D printing technology can be used to rapidly prototype the look and feel of 3D objects. However, the objects produced are passive. There has been increasing interest in making these objects interactive, yet they often require assembling components or complex calibration. In this paper, we contribute AirTouch, a techn…

JigFab: Computational Fabrication of Constraints to Facilitate Woodworking with Power Tools

We present JigFab, an integrated end-to-end system that supports casual makers in designing and fabricating constructions with power tools. Starting from a digital version of the construction, JigFab achieves this by generating various types of constraints that configure and physically aid the movement of a power tool…

StackMold: Rapid Prototyping of Functional Multi-Material Objects with Selective Levels of Surface Details

We present StackMold, a DIY molding technique to prototype multi-material and multi-colored objects with embedded electronics. The key concept of our approach is a novel multi-stage mold buildup in which casting operations are interleaved with the assembly of the mold to form independent compartments for casting diffe…
