Separate technical decisions are recommended for the use during modernization of existent knockout plants or at making the new one

Feature Use in Mobile Video Creation

Abstract. Today's mobile phones are also video cameras. People are using these ubiquitous cameras to document everyday surroundings as well as create more artistic videos. This paper examines emergent mobile film making patterns by tracking video composition and recording activities in ecologically valid contexts of use. We report the findings of a user study on user created mobile videos, where the actions of 11 active mobile video users were documented for 2 weeks. The collected material included diaries, device logs, and altogether 255 videos. Our findings characterize the features of a typical mobile video. Additionally, our study uncovers common practices, user motivations and pitfalls during filming and editing in the mobile contex

User interfaces for tangible characters: can children connect remotely through toy perspectives

ABSTRACT What if children's make-believe characters could keep in touch when the children were apart? We propose a novel concept for children's use of technology through imagination play: user interfaces designed to be used by children's character toys rather than directly by the children ("doll-computer interfaces"). We apply this model to the challenge of remote communication for children with an enhanced dollhouse containing small-scale interfaces for the dolls with a variety of fully functional multimodal communication functions. Using this interface as a technology probe, we explore a variety of design decisions with remote pairs of children. Our preliminary results suggest that toy-perspective and manipulable toy elements are particularly helpful in supporting play and successful use of communication technologies, while the "true-to-life" toy aspects are sensitive to individual frames of reference and more flexible interfaces that still fit within the toy context lead to creative communication strategies. We found that different communication channels offered interesting tradeoffs between uninterrupted play and rich verbal description. We also learned that the concept appeals to a wide age range but that the youngest children may need additional scaffolding for successful remote play

Interaction in motion: designing truly mobile interaction

The use of technology while being mobile now takes place in many areas of people’s lives in a wide range of scenarios, for example users cycle, climb, run and even swim while interacting with devices. Conflict between locomotion and system use can reduce interaction performance and also the ability to safely move. We discuss the risks of such “interaction in motion”, which we argue make it desirable to design with locomotion in mind. To aid such design we present a taxonomy and framework based on two key dimensions: relation of interaction task to locomotion task, and the amount that a locomotion activity inhibits use of input and output interfaces. We accompany this with four strategies for interaction in motion. With this work, we ultimately aim to enhance our understanding of what being “mobile” actually means for interaction, and help practitioners design truly mobile interactions

Cross-Device Taxonomy:Survey, Opportunities and Challenges of Interactions Spanning Across Multiple Devices

Designing interfaces or applications that move beyond the bounds of a single device screen enables new ways to engage with digital content. Research addressing the opportunities and challenges of interactions with multiple devices in concert is of continued focus in HCI research. To inform the future research agenda of this field, we contribute an analysis and taxonomy of a corpus of 510 papers in the cross- device computing domain. For both new and experienced researchers in the field we provide: an overview, historic trends and unified terminology of cross-device research; discussion of major and under-explored application areas; mapping of enabling technologies; synthesis of key interaction techniques spanning across multiple devices; and review of common evaluation strategies. We close with a discussion of open issues. Our taxonomy aims to create a unified terminology and common understanding for researchers in order to facilitate and stimulate future cross-device research
