Supporting Collaborative Multi-User Interactions in a Video Surveillance Application Using Microsoft Tabletop Surface

This report examines the progressing exploration done on my chosen subject, which is A Multi-touch Interface in a Video Surveillance System. It discusses method of early prototype interacting with security surveillance footage using natural user interfaces instead of traditional mouse and keyboard interaction. Current project is an evidence of idea on exhibiting that multi-touch interfaces are helpful in a video surveillance system to specifically control the surveillance videos, both of the live or of recorded. In case of any occurrence, this proposed system of interaction may require the user to spend an extra time amounts time obtaining circumstantial and location awareness, which is counter-beneficial. The framework proposed in this paper show how a multi-touch screen and natural interaction can empower the surveillance observing station users to rapidly recognize the area of a security camera and proficiently react to an occurrence. One of the main objective of this project is to engage more than 1 user to perform moving, scaling, rotating ,highlighting and recording on a surveillance video in the meantime, particularly during emergency periods. Furthermore, the scope of study for this project is to improve user collaborative interactions on Microsoft tabletop surface .A methodology was developed based upon a combination of the available literature and the experiences of the authors, who are actively involved with the development of multi-user interactions. This will cover many parts such as surveys, data gathering from respective Subject-Matter Experts, focal points, and analyzing information. It is intended to have a Surveillance application with user friendly collaborative touch on surface and eye-catching interface to reflect the quick paced nature of today's correspondences and better advertise its new activities and accessible assets. The future improvements and plans have been recommended and discussed in the recommendations section. Up to now, this research report has been run for twelve (12) weeks and going to be continued running for sixteen (16) weeks with a specific end goal to attain project primary objectives

Issues and techniques for collaborative music making on multi-touch surfaces

A range of systems exist for collaborative music making on multi-touch surfaces. Some of them have been highly successful, but currently there is no systematic way of designing them, to maximise collaboration for a particular user group. We are particularly interested in systems that will engage novices and experts. We designed a simple application in an initial attempt to clearly analyse some of the issues. Our application allows groups of users to express themselves in collaborative music making using pre-composed materials. User studies were video recorded and analysed using two techniques derived from Grounded Theory and Content Analysis. A questionnaire was also conducted and evaluated. Findings suggest that the application affords engaging interaction. Enhancements for collaborative music making on multi-touch surfaces are discussed. Finally, future work on the prototype is proposed to maximise engagement

RealTimeChess: Lessons from a Participatory Design Process for a Collaborative Multi-Touch, Multi-User Game

We report on a long-term participatory design process during which we designed and improved RealTimeChess, a collaborative but competitive game that is played using touch input by multiple people on a tabletop display. During the design process we integrated concurrent input from all players and pace control, allowing us to steer the interaction along a continuum between high-paced simultaneous and low-paced turn-based gameplay. In addition, we integrated tutorials for teaching interaction techniques, mechanisms to control territoriality, remote interaction, and alert feedback. Integrating these mechanism during the participatory design process allowed us to examine their effects in detail, revealing for instance effects of the competitive setting on the perception of awareness as well as territoriality. More generally, the resulting application provided us with a testbed to study interaction on shared tabletop surfaces and yielded insights important for other time-critical or attention-demanding applications.

Collaborative searching for video using the Físchlár system and a DiamondTouch table

Fischlar DT is one of a family of systems which support interactive searching and browsing through an archive of digital video information. Previous Fischlar systems have used a conventional screen, keyboard and mouse interface, but Fischlar-DT operates with using a horizontal, multiuser, touch sensitive tabletop known as a DiamondTouch. We present the Fischlar-DT system partly from a systems perspective, but mostly in terms of how its design and functionality supports collaborative searching. The contribution of the paper is thus the introduction of Fischlar-DT and a description of how design concerns for supporting collaborative search can be realised on a tabletop interface

Establishing the design knowledge for emerging interaction platforms

While awaiting a variety of innovative interactive products and services to appear in the market in the near future such as interactive tabletops, interactive TVs, public multi-touch walls, and other embedded appliances, this paper calls for preparation for the arrival of such interactive platforms based on their interactivity. We advocate studying, understanding and establishing the foundation for interaction characteristics and affordances and design implications for these platforms which we know will soon emerge and penetrate our everyday lives. We review some of the archetypal interaction platform categories of the future and highlight the current status of the design knowledge-base accumulated to date and the current rate of growth for each of these. We use example designs illustrating design issues and considerations based on the authors’ 12-year experience in pioneering novel applications in various forms and styles

Multi-touch interaction principles for collaborative real-time music activities: towards a pattern language

In this paper we give an analysis of the literature on a set of problems that can arise when undertaking the interaction design of multi-touch applications for collaborative real-time music activities, which are designed for multitouch technologies (e.g. smartphones, tablets, interactive tabletops, among others). Each problem is described, and a candidate design pattern (CDP) is suggested in the form of a short sentence and a diagram—an approach inspired by Christopher Alexander’s A Pattern Language. These solutions relate to the fundamental collaborative principles of democratic relationships, identities and collective interplay. We believe that this approach might disseminate forms of best design practice for collaborative music applications, in order to produce real-time musical systems which are collaborative and expressive

Work-In-Progress Technical Report: Designing A Two-User, Two-View TV Display

This work-in-progress paper previews how we can design interfaces and interactions for multi-view TVs, enabling users to transition between independent and shared activities, gain casual awareness of others’ activities, and collaborate more effectively. We first compare an Android-based multi-user TV against both multi-screen and multi-view TVs in a collaborative movie browsing task, to determine whether multiview can improve collaboration, and what level of awareness of each other’s activity users choose. Based on our findings, we iterate on our multi-view design in a second study, giving users the ability to transition between casual and focused modes of engagement, and dynamically set their engagement with other users’ activities. This research demonstrates that the shared focal point of the TV now has the capability to facilitate both collaborative and completely independent activity
