Many disciplines of multimedia and communication go towards ubiquitous computing and hands free-or no-touch interaction with computers. Application domains in this direction involve virtual reality, augmented reality, wearable computing, and smart spaces. Gesturing is one means of interaction and this paper presents some important issues in gesture(More)
Carnobacterium piscicola strain A9b isolated from cold smoked salmon inhibits growth of the food-borne pathogen Listeria monocytogenes partly due to the production of a proteinaceous compound (L. Nilsson, L. Gram, and H. H. Huss. J. Food Prot. 62:336-342, 1999). The purpose of the present study was to purify the compound and describe factors affecting its(More)
Many disciplines of multimedia and communication go towards ubiquitous computing and hand free interaction with computers. Application domains in this direction involve virtual reality, augmented reality, wearable computing, and smart spaces. This paper presents two main approaches to developing and testing these interfaces using gestures. It presents the(More)
This paper introduces a new concept within shadow seg-mentation for usage in shadow removal and augmentation through construction of an alpha overlay shadow model. Previously, an image was considered to consist of shadow and non-shadow regions. We construct a model that accounts for sunlit, umbra and penumbra regions. The model is based on theories about(More)
Over the past decade we have seen an increased awareness about domestic energy consumption and a growing focus on eco-feedback displays. In this paper we explore the concept of providing forecasts in such displays as a supplement to information about past usage. Our prototype, eForecast, extends the display of past electricity usage with forecasts about(More)
Over the past decade there has been an increased focus on eco-feedback systems for electricity consumption due to emerging technologies that allow detailed and real-time usage data to be collected and presented to users. In this paper, we present the design of an always-on eco-feedback display, PowerViz, that provides information about people's power usage(More)
Defining control scenarios in a smart home is a difficult task for end users. In particular, one concern is that user-defined scenarios could lead to unsafe or undesired state of the system. To help them explore scenario specifications, we propose in this paper a system that enables specification of constraints restricting the control commands that can be(More)
