Cabral, Diogo, Valente, Joo G., Arago, Urndia, Fernandes, Carla and Correia, Nuno (2012): Evaluation of a multimodal video annotator for contemporary dance. In: Proceedings of the 2012 International Conference on Advanced Visual Interfaces 2012. pp. 572-579.

This paper discusses the evaluation of a video annotator that supports multimodal annotation and is applied to contemporary dance as a creation tool. The Creation-Tool was conceived and designed to assist the creative processes of choreographers and dance performers, functioning as a digital notebook for personal annotations. The prototype, developed for Tablet PCs, allows video annotation in real-time, using a live video stream, or postevent, using a pre-recorded video stream. The tool also allows different video annotation modalities, such as annotation marks, text, audio, ink strokes and hyperlinks. In addition, the system enables different modes of annotation and video visualization. The development followed an iterative design process involving two choreographers, and a usability study was carried out, involving international dance performers participating in a contemporary dance "residence -- workshop".

Cabral, Diogo and Correia, Nuno (2012): VideoInk: a pen-based approach for video editing. In: Adjunct Proceedings of the 2012 ACM Symposium on User Interface Software and Technology 2012. pp. 67-68.

Due the growth of video sharing, its manipulation is important, however still a hard task. In order to improve it, this work proposes a pen-based approach, called VideoInk. The concept exploits the painting metaphor, replacing digital ink with video frames. The method allows the user to paint video content in a canvas, which works as a two dimensional timeline. This approach includes transition effects and zoom features based on pen pressure. A Tablet PC prototype implementing the concept was also developed.

Cabral, Diogo, Carvalho, Urndia, Silva, Joo, Valente, Joo, Fernandes, Carla and Correia, Nuno (2011): Multimodal video annotation for contemporary dance creation. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 2293-2298.

This paper presents a video annotator that supports multimodal annotation and is applied to contemporary dance as a creation tool. The prototype, developed for Tablet PCs, explores bimanual interaction, using pen and touch input interfaces. This combination can be more natural and familiar than the traditional input interfaces (keyboard or mouse). Contemporary dance is a domain where this type of flexible interaction with video material is relevant in order to augment and improve the rehearsal and creative processes. Motion tracking is used to define the dynamic behavior of the annotations and voice input complements the other modalities. The paper describes the design decisions done by the multidisciplinary development team and the current status of the tool.
