A Study of Street-level Navigation Techniques in 3D Digital Cities on Mobile Touch Devices

International audienceTo characterize currently most common interaction techniques for street-level navigation in 3D digital cities for mobile touch de- vices in terms of their efficiency and usability, we conducted a user study, where we compared target selection (Go-To), rate con- trol (Joystick), position control, and stroke-based control naviga- tion metaphors. The results suggest users performed best with the Go-To interaction technique. The subjective comments showed a preference of novices towards Go-To and expert users towards Joy- stick technique

Integrating Haptic Feedback into Mobile Location Based Services

Haptics is a feedback technology that takes advantage of the human sense of touch by applying forces, vibrations, and/or motions to a haptic-enabled device such as a mobile phone. Historically, human-computer interaction has been visual - text and images on the screen. Haptic feedback can be an important additional method especially in Mobile Location Based Services such as knowledge discovery, pedestrian navigation and notification systems. A knowledge discovery system called the Haptic GeoWand is a low interaction system that allows users to query geo-tagged data around them by using a point-and-scan technique with their mobile device. Haptic Pedestrian is a navigation system for walkers. Four prototypes have been developed classified according to the user’s guidance requirements, the user type (based on spatial skills), and overall system complexity. Haptic Transit is a notification system that provides spatial information to the users of public transport. In all these systems, haptic feedback is used to convey information about location, orientation, density and distance by use of the vibration alarm with varying frequencies and patterns to help understand the physical environment. Trials elicited positive responses from the users who see benefit in being provided with a “heads up” approach to mobile navigation. Results from a memory recall test show that the users of haptic feedback for navigation had better memory recall of the region traversed than the users of landmark images. Haptics integrated into a multi-modal navigation system provides more usable, less distracting but more effective interaction than conventional systems. Enhancements to the current work could include integration of contextual information, detailed large-scale user trials and the exploration of using haptics within confined indoor spaces

Revisiting the city, augmented with digital technologies: The SeeARch tool

This paper presents a digital tool that enables the city inhabitants or visitors to acquire in real time, relevant information about several aspects of a given city, augmenting their real experience of the place. We used digital technologies, particularly an in-house developed Augmented Reality (AR) tool referred to as SeeARch,that augments in situ the city explo-ration experience. This tablet-based AR tool, enables mobile users to recognize the facade of specific buildings and, in real-time, superimpose relevant associated 3D and multimedia information, while visiting the city. The aim of this app is to provide customized infor-mation to visitors suiting their own interests and time to visit the city. User satisfaction evaluation tests were performed with a sample of the potential users. The outcomes of such user studies, showed that participants considered that our approach delivers a more detailed knowledge about the city, and is more informative, when compared with the nor-mal sight-seeing visits in the city, performed by the same participants.info:eu-repo/semantics/acceptedVersio

Multimodal Content Delivery for Geo-services

This thesis describes a body of work carried out over several research projects in the area of multimodal interaction for location-based services. Research in this area has progressed from using simulated mobile environments to demonstrate the visual modality, to the ubiquitous delivery of rich media using multimodal interfaces (geo- services). To effectively deliver these services, research focused on innovative solutions to real-world problems in a number of disciplines including geo-location, mobile spatial interaction, location-based services, rich media interfaces and auditory user interfaces. My original contributions to knowledge are made in the areas of multimodal interaction underpinned by advances in geo-location technology and supported by the proliferation of mobile device technology into modern life. Accurate positioning is a known problem for location-based services, contributions in the area of mobile positioning demonstrate a hybrid positioning technology for mobile devices that uses terrestrial beacons to trilaterate position. Information overload is an active concern for location-based applications that struggle to manage large amounts of data, contributions in the area of egocentric visibility that filter data based on field-of-view demonstrate novel forms of multimodal input. One of the more pertinent characteristics of these applications is the delivery or output modality employed (auditory, visual or tactile). Further contributions in the area of multimodal content delivery are made, where multiple modalities are used to deliver information using graphical user interfaces, tactile interfaces and more notably auditory user interfaces. It is demonstrated how a combination of these interfaces can be used to synergistically deliver context sensitive rich media to users - in a responsive way - based on usage scenarios that consider the affordance of the device, the geographical position and bearing of the device and also the location of the device

BlueEyes: assistive technology for visually impaired and blind people - a bluetooth

This report is presented to draw one solution “people to people” (P2P) through the mobile technology that promotes the change in the field of sustainability in relation to the Application system. The HCI interaction field, as the basis for the study of this project, is defined as a multidisciplinary field of knowledge, focusing on the design of computer technology and, in particular, on the interaction between humans and computers. For the development of this project it was necessary enough research information on the technologies that will be needed to create an application mobile. All this research and design belongs to just one of the various stages of this project that has the base of operations at ESEC

New approaches for mixed reality in urban environments: the CINeSPACE project

The CINeSPACE (www.cinespace.eu) project allows tourists to access the rich cultural heritage of urban environments by literally morphing the user into the past through the use of multimedia archives. Tourists use the device which includes both a PDA type of device with a GIS interface displayed on a touch screen to help the user navigate and select multimedia content, and video binoculars to create the augmented reality effects. In addition to this mode of interaction, a survey of Mixed Reality user interaction paradigms will be presented. A key feature of Mixed Reality user interfaces is the object identification and annotation methods available to the user, of which a survey, including a review of the GeoConcepts ontology annotation methodology used in the CINeSPACE device, will be presented.Peer Reviewe
