Background Establishing a methodology for assessing nutritional behavior comprehensively and accurately poses great challenge. Mobile technologies such as mobile image-based food recording apps enable eating events to be assessed in the moment real time, thereby reducing memory biases inherent retrospective records. However, users might find it challenging take images of they consume at every event over an extended period, which lead incomplete records (missing events). Objective Analyzing...

We present two experiments examining the impact of navigation techniques on users' performance and spatial memory in a zoomable user interface (ZUI). The first experiment with 24 participants compared effect egocentric body movements traditional multi-touch navigation. results indicate 47% decrease path lengths 34% task time favor navigation, but no significant immediately after task. However, an additional second 8 revealed such increase long-term memory: recall administered 15-minute...

In today's digital control rooms, desktop computers represent the most common interface for process control. Compared to their predecessors -- manual actuators enable quick and effective intervention but they lack in process-related interaction qualities such as haptic feedback involvement of motor skills. Thus, design trade-offs have be made combine strengths both paradigms: processing power with former room interfaces. this paper related concepts are presented evaluated. a scenario,...

We present SMARTEXPLORE, a novel visual analytics technique that simplifies the identification and understanding of clusters, correlations, complex patterns in high-dimensional data. The analysis is integrated into an interactive table-based visualization maintains consistent familiar representation throughout analysis. tightly coupled with pattern matching, subspace analysis, reordering, layout algorithms. To increase analyst's trust revealed patterns, SMARTEXPLORE automatically selects...

Many tasks performed in multiscale visual spaces require the user to have several foci. Using bimanual interaction, multitouch devices can facilitate simultaneous definition and exploration of However, is rarely used for multifocus navigation, may limit interaction a sequential areas interest. We introduce two novel navigation techniques that combine multiple foci touch, therefore enable isochronic interest, leading navigation. SpaceFold folds space third dimension, allowing users bring...

Forecasting how we will react in the future is important every area of our lives. However, people often demonstrate an 'impact bias' which leads them to inaccurately forecast their affective reactions distinct and outstanding events. The present study examined forecasting accuracy for a day-to-day repetitive experience have wealth past experiences (eating happiness), along with dispositional expectations towards eating ('foodiness'). Seventy-three participants (67.12% women, Mage = 41.85...

Context-sensitive information is of vital importance to the monitoring processes in control rooms, but its incorporation current state-of-the-art user interfaces inadequate. By looking at a traffic center as an example, this paper proposes interaction concept for complex networks on large remote displays. Our approach based content-aware navigation with goal improve road network and availability context-sensitive information. We conducted study comparing different techniques well two visualizing

Personalized and contextual interventions are promising techniques for mobile persuasive technologies in health. In this paper, we propose the "fingerprints" technique to analyze users' daily behavior patterns find meaningful moments better support technologies, especially health interventions. We assume that many persons, their behaviors have can be detected through sensor data from smartphones. develop a three-step interactive machine learning workflow describe concept approach of...

OPAC interfaces, still the dominant access point to library catalogs, support systematic search but are problematic for open-ended exploration and generally unpopular with visitors. As a result, libraries start subscribing simplified paradigms as exemplified by web-search systems. This is problem considering that crucial skill in light of today's abundance digital information. Inspired novel approaches facilitating search, we designed CollectionDiver, an installation supporting public...

Mobile intervention studies employ mobile devices to observe participants' behavior change over several weeks. Researchers regularly monitor high-dimensional data streams ensure quality and prevent loss (e.g., missing engagement or malfunctions). The multitude of problem sources hampers possible automated detection such irregularities – providing a use case for interactive dashboards. With the advent untethered head-mounted AR devices, these dashboards can be placed anywhere in user's...

In this paper we propose Mixed Reality (MR) interfaces as tools for the analysis and exploration of health-related data. Reported findings originate from research project "SMARTACT" in which several intervention studies are conducted to investigate how participants' long-term health behavior can be improved. We a focus group identify limitations current data technologies practices, possible uses MR associated open questions leverage their potentials given domain.

In the VAST Challenge 2009 suspicious behavior had to be detected applying visual analytics heterogeneous data, such as network traffic, social enriched with geo-spatial attributes, and finally video surveillance data. This paper describes some of awarded parts from our solution entry.

Many tasks that have to be performed analyze data in large visual information spaces require the user several foci. This is for example case comparing or organizing digital artefacts. In my research, I explore alternative interaction concepts multi-focus visualizations context of single and multi-user scenarios. Alongside explicit navigating within investigate implicit making visualization react on social spatial context. To evaluate different designs, measures like task completion time,...

Deformable displays can provide two major benefits compared to rigid displays: Objects of different shapes and deformabilities, situated in our physical environment, be equipped with deformable displays, users benefit from their pre-existing knowledge about the interaction objects when interacting displays. In this article we present InformationSense, a large, highly cloth display. The contributes research areas context It presents an approach for tracking surfaces, it one first UX analyses...

Augmented Reality (AR) displays have been suggested as shared-space technology to support remote collaboration, e.g., in design and building tasks. But with AR displays, the shared space typically consists of only virtual work objects (e.g., artifacts) while collaborators' interaction is grounded their individual, physical environment. This can become problematic during activities that involve positioning because collaborators may require spatial references coordinate actions. In a lab...

Distortion-based visualization techniques allow users to examine focused regions of a multiscale space at high scales but preserve their contextual information. However, the distortion can come coast confusion, disorientation and impairment users' spatial memory. Yet, how distortions influence ability build up memory, while taking into account human skills perception, interpretation comprehension, remains underexplored. This note reports findings an experimental comparison between...
