“…A group of researchers in Finland (Oulasvirta, Tamminen, Roto, & Kuorelahti, 2005;Tamminen, Oulasvirta, Toiskallio, & Kankainen, 2004) observed the concept of temporal tensions and defined it as the psychological construct based on assessing the availability of temporal, mental, physical and social resources. Sometimes it is necessary to fit more actions into a given time frame.…”

This research proposes that it is possible to deliberately reduce temporal tensions in order to promote energy saving behaviours. People may not dedicate enough time to planning their tasks that consume energy, rushing into them without much deliberation. They may also use more energy than necessary in an attempt to accelerate processes that seem to be taking too long, to reduce the boredom of waiting. Persuasive technology provided the tools to manipulate the perception of time and therefore elicit changes in the specific behaviours that result in unnecessary energy usage. Cooking tasks were used as the scenario to test behaviour change strategies delivered via a smartphone application. Results showed that these strategies facilitated the performance of sustainable behaviours. Participants reported that the app made (1) them more likely to follow the steps needed to use less energy, (2) the activity more enjoyable and (3) the time appear to pass more quickly compared to a control version.

“…For instance, mobile text entry is different from desktop text entry [22,30], and typing on a tactile keyboard requires little or no visual attention, whereas text entry on a touch surface requires visual attention. Thus, text entry in non-desktop settings presents new challenges and requires new methods [39].…”

Abstract. Most text entry methods require users to have physical devices within reach. In many contexts of use, such as around large displays where users need to move freely, device-dependent methods are ill suited. We explore how selection-based text entry methods may be adapted for use in mid-air. Initially, we analyze the design space for text entry in mid-air, focusing on singlecharacter input with one hand. We propose three text entry methods: H4 MidAir (an adaptation of a game controller-based method by MacKenzie et al.[21]), MultiTap (a mid-air variant of a mobile phone text entry method), and Projected QWERTY (a mid-air variant of the QWERTY keyboard). After six sessions, participants reached an average of 13.2 words per minute (WPM) with the most successful method, Projected QWERTY. Users rated this method highest on satisfaction and it resulted in the least physical movement.

“…on a map, and directly overlaying the information on the live camera images makes it easier to gather, process and understand the presented information, and ultimately draw conclusions based on them. This is specifically important for mobile usage scenarios where a user's attention span is typically limited to less than 30 seconds [31]. For instance by trend, people find it easier to get an understanding of a forecasted wind direction and intensity when visualised using animated arrows (s. Figure 6) [32] as opposed to the raw data indicating a cardinal direction of SW with 20 km/h.…”

Abstract-Even though advantages of 3D visualisation of multi-temporal geo-data versus 2D approaches have been widely proven, the particular pertaining challenge of realtime visualisation of geo-data in mobile Digital Earth applications has not been thoroughly tackled so far. In the emerging field of Augmented Reality (AR), research needs comprise finding the optimal information density, the interplay between orientation data in the background and other information layers, using the appropriate graphical variables for display, or selecting real-time base data with adequate quality and suitable spatial accuracy. In this paper we present a concept for integrating real-time data into 4D (three spatial dimensions plus time) AR environments, i.e., data with "high" spatial and temporal variations. We focus on three research challenges: 1.) high-performance integration of real-time data into AR; 2.) usability design in terms of displaying spatio-temporal developments and the interaction with the application; and 3.) design considerations regarding reality vs. virtuality, visualisation complexity and information density. We validated our approach in a prototypical application and extracted several limitations and future research areas including natural feature recognition, the cross-connection of (oftentimes monolithic) AR interface developments and well-established cartographic principles, or fostering the understanding of the temporal context in dynamic 4D Augmented Reality environments.
