ShareDay: A Multi-modal Lifelog System forGroup SharingLijuan Marissa Zhou1, Niamh Caprani1,2, Cathal Gurrin1, and Noel E.O’Connor21 CLARITY: Centre for Sensor Web Technologies, Dublin City University2 School of Electronic Engineering, Dublin City University{mzhou,ncaprani,cgurrin}@computing.dcu.ie,oconnorn@eeng.dcu.ieAbstract. Lifelogging is the automatic capture of daily activities usingenvironmental and wearable sensors such as MobilePhone/SenseCam.The potential to capture such a large data collection presents many chal-lenges, including data analysis, visualisation and motivating users of dif-ferent ages and technology experience to lifelog. In this paper, we presenta new generation of lifelog system to support reminiscence through in-corporating event segmentation and group sharing.Keywords: Multimedia System, Group Sharing, Lifelogging, Touch Screen1 IntroductionWith the recent availability of wearable sensing technologies and an acceptanceof personal data gathering and on-line social sharing (e.g, on Facebook timeline),lifelogging has become a mainstream research topic. We now have the ability togather and store large volumes of personal data using an inexpensive smartphone. However, with many available lifelogging tools, how to collect, organizeand represent lifelog data is still under much discussion [1, 2].Furthermore, people have always collected mementos over lifetime. With thedigitization of mementos (photos and videos etc.), researchers have begun torealize the benefit of this to support reminiscence[3]. Sharing digital informationis already commonplace, through emails, mobile phones and social networks.However, sharing lifelog data between family members, to our knowledge, hasnot yet been looked at. Shared reminiscence between family members can servemany functions such as maintaining memories of past relatives, creating bondsand teaching younger family members from the elders’ experiences. We believethat sharing lifelogs within a family would enrich reminiscence and story-telling.In this paper we describe a novel software system to support sharing lifelog.2 ShareDayA previous study on intergenerational sharing [4] has shown that both older andyounger people were more likely to wear a lifelogging device for the purpose ofsharing images rather than simply wearing a lifelog device for private browsing orreminiscence. ShareDay was designed to support browsing and sharing throughlifelogs on cross-platforms. To support family reminiscence we have designed thesystem to be used on a touch screen device displayed in a communal area athome so that all family members can upload, view and share their lifelogs. Userscan also view specific person’s shared data by clicking on their profile (see Figure1). The lifelog data can be viewed in two modes: personal and family. In familyview, all group members can see all daily events and images in an overall, sharedor favourite view. In personal view, only the logged-user can upload data andview their data. If logged, users can manage (share, mark as favourite or delete)and browse their visual lifelogs. There are three main functions incorporatedinto the ShareDay system: managing personal data, shared data and favouritedata. Fig.1 is the main view of the system, which shows all events gathered byall family members in that day. These functions will be described as follows.Fig. 1. ShareDay System Overview: Family View2.1 Managing Personal Lifelog DataTo collect a personal lifelog, the user must initially capture images and uploadthem to the system. Visual lifelogs present a challenge for developers as theyneed to represent the users day accurately and in a user-friendly manner, withoutrequiring the user to browse through up to 5,000 images per day. We integratedan event segmentation model[5], which organizes a sequence of SenseCam imagesinto a set of events. Events represent daily activities such as walking, eating,shopping, talking, etc. Keyframe images representing events are selected anddisplayed for each event, with six large keyframe images being selected for eachevent. When a user is logged in they can manage (share, favourite or delete)and browse through their visual lifelog. With regard to sharing, logged user canshare/mark favourite their daily events/images, so other family members cansee shared data, which is designed under the concern of privacy.2.2 Sharing Lifelog DataThe initial screen of the system displays shared lifelog of each family member.The user can touch on the name of their family member to view lifelogs. A usercan also browse through shared lifelogs organized chronologically by touching theShared tab. Group sharing to support family reminiscence is the primary aim ofthe proposed lifelog management system. However, we also wanted to ensure thatusers had control over their own lifelogs as the content can be extremely personal.To accommodate for this users can select to share images/events when they arelogged into their accounts. These images will automatically be transferred tocommunal lifelog data set which all members of the family can view.2.3 Favourite Lifelog DataIn our previous studies the participants reported that when they wanted toshare images they had difficulty finding the images due to the vast data setaccumulated[2, 4]. An easy fix for this was to provide users with a Favouritesbutton. These selected images are automatically duplicated into a favouritesfolder which users can find on the main menu bar.3 Discussion and ConclusionWe demonstrate a novel lifelogging system for group sharing, which emphasizeson sociability of SenseCam users. In future, we will conduct more user studieson influence of group sharing/favourite to personal lifelog and reminiscence.4 AcknowledgementThis research is supported by SFI(11/RFP.1/CMS/3283) and Embark Initiative.References1.
