Multitag


MULTITAG is research project between the Computing Department of Lancaster University and DOCOMO Euro-Labs which is funded by the latter. The goal of the project is to develop new methods and applications for mobile interactions with multi-tagged objects. This project was launched in January 2008 and has a planned overall duration of four years.

Overview

Mobile interaction with things, places and people based on NFC tags or visual markers is regarded as a promising application area in mobile commerce. However, most currently implemented commercial applications are based on simple interaction paradigms, which associate one single object with exactly one tag to provide one single link to exactly one service at a time. As an extension to this rather limited commercial settings, multi-tag interactions and applications are driven by the idea of augmenting objects through multiple tags that provide various links to different services. The concept of multi-tag interaction was initially exploited within the PERCI project which was funded by DoCoMo Euro-Labs and promises to hold great potential for new mobile services that provide an added value to the customer.

The aim of the herein MULTITAG project is to further analyze multi-tag application and interactions, to define guidelines for the development of such systems, as well as to establish tool support and a solid service engineering basis for the future development of such services.

Many interactions naturally extend across smart-phones and devices with larger screens. Indeed, data might be received on the mobile but more conveniently processed with an application on a larger device, or vice versa. Such interactions require spontaneous data transfer from a source location on one screen to a target loca- tion on the other device. We introduce a cross-device Drag-and- Drop technique to facilitate these interactions involving multiple touchscreen devices, with minimal effort for the user. The technique is a two-handed gesture, where one hand is used to suitably align the mobile phone with the larger screen, while the other is used to select and drag an object between devices and choose which application should receive the data.

One of the most popular scenarios for advertising interactive surfaces in the home is their support for solving co-located collaborative tasks. Examples include joint planning of events (e.g., holidays) or deciding on a shared purchase (e.g., a present for a common friend). However, this usually implies that all interactions with information happen on the common display. This is in contrast to the current practices to use personal devices and further, most people's behavior to constantly switch between individual and group phases because people have differing search strategies, preferences, etc. We therefore investigated how the combination of personal devices and a simple way of exchanging information between these devices and an interactive surface changes the way people solve collaborative tasks compared to an existing approach of using personal devices. Our study results clearly indicate that the combination of personal and a shared device allows users to fluently switch between individual and group work phases and users take advantage of both device classes.

We present the technical framework supporting a cross-device Drag-and-Drop technique designed to facilitate interactions involving multiple touchscreen devices. This technique supports users that need to transfer information received or produced on one device to another device which might be more suited to process it. Furthermore, it does not require any additional instrumentation. The technique is a two-handed gesture where one hand is used to suitably align the mobile phone with the larger screen, while the other is used to select and drag an object from one device to the other where it can be applied directly onto a target application. We describe the implementation of the framework that enables spontaneous data-transfer between a mobile device and a desktop computer.
