Due to advances in technology large displays with very high resolution started to become affordable for daily work. Today it is possible to build display walls with a pixel density that is comparable to standard office screens. Previous work indicates that physical navigation enables a deeper engagement with the data set. In particular, the visibility of(More)
Order Picking is not only one of the most important but also most mentally demanding and error-prone tasks in the industry. Both stationary and wearable systems have been introduced to facilitate this task. Existing stationary systems are not scalable because of the high cost and wearable systems have issues being accepted by the workers. In this paper, we(More)
Synchronous colocated collaborative sensemaking requires that analysts share their information and insights with each other. The challenge is to know when is the right time to share what information without disrupting the present state of analysis. This is crucial in ad-hoc sensemaking sessions with mobile devices because small screen space limits(More)
This paper introduces Thaddeus---a mobile phone-tablet system for mobile interaction with information visualisations. Our work is motivated by the roles smartphones and tablets play in everyday interactive spaces as well as anticipated developments in mobile sensing technology. We also aim to meet the social challenges of a data-driven society. We designed(More)
The increasing availability of drones produces a number of opportunities for integrating them in everyday settings and using drones to create engaging experiences for users. In this paper, we investigate how drones can support amateur runners in their endeavours. We explore the possible roles for drones during amateur running races. Through two field(More)
We present MochaTop-a system using multiple mobile devices that is part of our on-going inquiry into ad-hoc multi-device environments on tabletops. In this progress report, we describe the motivation for designing multi-device, ad-hoc systems for single and multiple users, and explain the design and implementation of our prototype system. We report on(More)
Large screen displays are part of many future visions, such as i-LAND that describes the possible workspace of the future. Research showed that wall-sized screens provide clear benefits for data exploration, collaboration and organizing work in office environments. With the increase of computational power and falling display prices wall-sized screens(More)
Despite the proliferation of screens in everyday environments, providing values to remote displays for exploring complex data sets is still challenging. Enhanced input for remote screens can increase their utility and enable the construction of rich data-driven environments. Here, we investigate the opportunities provided by a variable movement resistance(More)
Pixel densities are increasing rapidly. We can observe this trend in particular for mobile devices like smartphones and tablets. Previous work revealed an effect of pixel density on subjective feedback and objective performance only for low resolution cathode ray tube screens. It is unclear if this effect persists for the four times higher pixel densities(More)
