Annotation interaction and relocation using a Handheld Projector

May cause dizziness: applying the simulator sickness questionnaire to handheld projector interaction

Previous user studies have suggested the occurrence of symptoms of motion or simulator sickness among active spectators of handheld projector interaction. Using the well-established Simulator Sickness Questionnaire proposed by Kennedy et al. in 1993, we asked twenty-six participants if they had any indication of such symptoms after they watched a demonstration of handheld projector interaction ...

In-place Annotation of Physical Objects with Pico- Projectors

Just as we annotate digital documents with digital annotations for collaborative work, we frequently annotate physical objects using physical annotations (e.g. by using Post-It notes). In the physical world, we are limited by the size of the physical Post-It note, and further, too many Post-It notes clutter the physical space. In this work, we explore the use of handheld projectors combined wit...

Animation & Sequential Art Principles for Handheld Projector Interaction

We present a brief history of historic handheld projection devices and introduce design techniques for handheld projector interaction that draw from the principles of traditional animation and sequential art. Our approach is to utilize the movement of the handheld projector to express the motion and physicality of projected foreground objects. Users interact and control the projected image by m...

A Handheld Projector Supported by Computer Vision

This paper describes the use of computer vision to support the operation of a handheld projector, and describes four applications. Projectors in the past have been used as fixed devices, but the latest generation of ’pocket projectors’ is small and portable. We demonstrate the feasibility of using a projector held in the hand, and the types of applications that can be done with a handheld proje...
