“…Peephole displays (Yee, 2003) involved pen interaction on spatially aware handheld computers. Many recent proposals for integrating phones and situated displays have sought to use visually-controlled interaction, such as the Mobile Magic Hand (Yoshida et al, 2007), which allows a user to manipulate virtual objects using the measured optical flow in an image sequence, when observing a visual code. Wang and co-researchers developed motion estimation techniques for a cameraequipped phone that derive from full-search block matching, similar to those used by MPEG video encoders (Wang et al, 2006).…”

Abstract:We present further developments of our system that allows direction interaction between a camera-equipped hand-held device and a remote display. The essence of this system is the ability to estimate a planar projectivity between the remote display and the displayed image of that display on the handheld device. We describe how to achieve this by matching scale invariant SURF features across the two displays (remote and hand-held).We implement a prototype system and a drawing application and conduct both performance and usability evaluations. The feedback given indicates that our system is responsive, accurate and easy to use.

Atualmente, existem diferentes possibilidades de acessar conteúdos pedagógicos digitais, tais como Internet, dispositivos móveis e, inclusive, TV digital. Um problema relevante, no entanto, é que nem sempre os dispositivos estão disponíveis ao usuário (aluno). Nesse contexto, este artigo propõe o uso do papel como meio de aprendizagem ubíqua (integrado a estratégias pedagógicas), podendo ser utilizado ainda como mecanismo de interação ou entrada de dados para outros dispositivos. O artigo também apresenta uma sugestão de estratégia que pode ser usada em sala de aula e/ou no âmbito do elearning e m-learning.
