Deformable interfaces are emerging in HCI and prototypes show potential for non-rigid
interactions. Previous reviews looked at deformation as a material property of shape …

Virtual Reality (VR) can enhance the display and interaction of mobile knowledge work and
in particular, spreadsheet applications. While spreadsheets are widely used yet are …

Virtual Reality (VR) has the potential to support mobile knowledge workers by
complementing traditional input devices with a large three-dimensional output space and …

We propose mounting a downward-facing camera above the top end of a digital tablet pen.
This creates a unique and practical viewing angle for capturing the pen-holding hand and …

Digital pen interaction has become a first-class input modality for precision tasks such as
writing, annotating, drawing, and 2D manipulation. The key enablers of digital inking are the …

We present ShArc, a precision, geometric measurement technique for building multi-
bend/shape sensors. ShArc sensors are made from flexible strips that can be dynamically …

We present Print-A-Sketch, an open-source handheld printer prototype for sketching circuits
and sensors. Print-A-Sketch combines desirable properties from free-hand sketching and …

We introduce a new pen input space by forming postures with the same hand that also grips
the pen while writing, drawing, or selecting. The postures contact the multitouch surface …

Digital pen input devices based on absolute pen position sensing, such as Wacom Pens,
support high-fidelity pen input. However, they require specialized sensing surfaces like …

We conduct a two-part study to better understand pen grip postures for general input like
mode switching and com-mand invocation. The first part of the study asks participants what …
