ShareDay: A new lifelogging brower system for group sharing

SenseCam is a small lightweight wearable camera used to passively capture photos and other sensor data(temperature, accelerometer, magnitude, infrared ray etc.) mainly for the use of reminiscence. But big amount of SenseCam data analysis and constructing for better application in human daily life is a big challenge. In this paper, we rep- resent a new generation of personal life log application system for group sharing based on user study. Dierent from similar lifelogging browsers, our system incorporate event segmentation and group sharing

Touch Screens for the Older User

It has been 20 years since Ben Schneiderman predicted that there would be an increase in the use of touch screen applications yet it has been only in recent years that this prediction has come to pass. The concept of a touch screen computer was first introduced in 1965 by E.A. Johnson who described the possibilities of touch screen technology to support air traffic controllers. In this article Johnson describes how the touch display coupled to a computer can be considered as a keyboard, a novel approach at the time. Touch screens were brought into the public domain in 1971 by Elographics, Inc. which instigated the development of public touch screen technology such as automated teller machines (ATMs) and information kiosks (Brown et al., 2011). Another milestone in the history of touch technology was the introduction of the personal touch screen computer, HP-150, developed by Hewlett-Packard in 1983 (Sukumar, 1984). The purpose of this early design was to offer individuals an intuitive technology option. Although touch screen systems have maintained this intuitiveness and ease of use over the years, problems that existed with early systems still provide challenges for designers and developers to this day.

Designing an Educational and Intelligent Human-Computer Interface for Older Adults

As computing devices continue to become more heavily integrated into our lives, proper design of human-computer interfaces becomes a more important topic of discussion. Efficient and useful human-computer interfaces need to take into account the abilities of the humans who will be using such interfaces, and adapt to difficulties that different users may face – such as the particular difficulties older users must face. However, various issues in the design of human-computer interfaces for older users yet exist: a wide variance of ability is displayed by older adults, which can be difficult to design for. Motions and notions found intuitive by younger users can be anything but for the older user. Properly-designed devices must also assist without injuring the pride and independence of the users – thus, it’s understood that devices designed “for the elderly” may encounter a poor reception when introduced to the ageing community. Affective computing gives current researchers in HCI a useful opportunity to develop applications with interfaces that detect mood and attention via nonverbal cues and take appropriate actions accordingly. Current work in affective computing applications with older adult users points to possibilities reducing feelings of loneliness in the older adult population via these affective applications. However, we believe that everyday applications – such as chat programs or operating systems – can also take advantage of affective computing principles to make themselves more accessible for older adults, via communication enhancement. In this thesis, we document a variety of work in the field of developing human-computer interfaces for the older adult user, and the various requirements each of these studies confirm regarding human-computer interaction design for the elderly. We then explain how integration of affective computing can positively affect these designs, and outline a design approach for proper human-computer interfaces for the elderly which take into account affective computing principles. We then develop a case study around a chat application – ChitChat – which takes these principles and guidelines into account from the beginning, and give several examples of real-world applications also built with these guidelines. Finally, we conclude by summarizing the broader impacts of this work

LifeLogging: personal big data

We have recently observed a convergence of technologies to foster the emergence of lifelogging as a mainstream activity. Computer storage has become significantly cheaper, and advancements in sensing technology allows for the efficient sensing of personal activities, locations and the environment. This is best seen in the growing popularity of the quantified self movement, in which life activities are tracked using wearable sensors in the hope of better understanding human performance in a variety of tasks. This review aims to provide a comprehensive summary of lifelogging, to cover its research history, current technologies, and applications. Thus far, most of the lifelogging research has focused predominantly on visual lifelogging in order to capture life details of life activities, hence we maintain this focus in this review. However, we also reflect on the challenges lifelogging poses to an information retrieval scientist. This review is a suitable reference for those seeking a information retrieval scientist’s perspective on lifelogging and the quantified self

Case studies in therapeutic SenseCam use aimed at identity maintenance in early stage dementia

In the absence of a medical cure for memory loss new technologies specialised in pervasive imaging are being incorporated into interventions for dementia. The practice of lifelogging is a digital capture of life experiences typically through mobile devices such as SenseCam. The lightweight wearable digital camera passively captures about 3,000 images a day. Lifelogging results in personal, recent prompts, potentially encouraging sharing of personal memories. This research investigated the incorporation of lifelogging technology into a therapeutic approach aimed to support people with dementia by using the Case Study method, an exploratory and descriptive approach. The case study is a method of empirical inquiry that enables investigation of phenomenon within its real life context. SenseCam therapy aimed to stimulate the cognition of a person with dementia, with support of their personal identity as its primary goal. SenseCam images were used as cues to meaningful discussions about the person’s recent memories. The images enabled a construction of a particular version of the participants’ identities mainly based in their recent past. On the contrary participants seemed to valorise their identity of their distant past. The SenseCam identity also contained uncensored details from participants’ lives as revealed by review of SenseCam images. The exposing nature of SenseCam images posed risks to the users’ privacy and showed the potential ethical risks of using lifelogging technology with people with dementia. There is limited literature on the practical recommendations on how to use lifelogging devices and how they affect people with dementia. The results from this research indicate that a number of factors should be considered when using lifelogging technology with people with dementia. Firstly the contextual factors of people with dementia including the level of cognitive impairment, existing coping mechanisms and the interaction patterns with the carer need to be considered. Secondly the technology should be used within a therapeutic framework and tailored to suit the individual needs of both people with dementia and their carers. Lastly intimate and unexpected details from the participant’s life should be discussed in an ethical and sensitive manner. Implications of not working within these boundaries show clear potential for undermining the human rights and potentially the wellbeing of people with dementia

Digital life stories: Semi-automatic (auto)biographies within lifelog collections

Our life stories enable us to reflect upon and share our personal histories. Through emerging digital technologies the possibility of collecting life experiences digitally is increasingly feasible; consequently so is the potential to create a digital counterpart to our personal narratives. In this work, lifelogging tools are used to collect digital artifacts continuously and passively throughout our day. These include images, documents, emails and webpages accessed; texts messages and mobile activity. This range of data when brought together is known as a lifelog. Given the complexity, volume and multimodal nature of such collections, it is clear that there are significant challenges to be addressed in order to achieve coherent and meaningful digital narratives of our events from our life histories. This work investigates the construction of personal digital narratives from lifelog collections. It examines the underlying questions, issues and challenges relating to construction of personal digital narratives from lifelogs. Fundamentally, it addresses how to organize and transform data sampled from an individual’s day-to-day activities into a coherent narrative account. This enquiry is enabled by three 20-month long-term lifelogs collected by participants and produces a narrative system which enables the semi-automatic construction of digital stories from lifelog content. Inspired by probative studies conducted into current practices of curation, from which a set of fundamental requirements are established, this solution employs a 2-dimensional spatial framework for storytelling. It delivers integrated support for the structuring of lifelog content and its distillation into storyform through information retrieval approaches. We describe and contribute flexible algorithmic approaches to achieve both. Finally, this research inquiry yields qualitative and quantitative insights into such digital narratives and their generation, composition and construction. The opportunities for such personal narrative accounts to enable recollection, reminiscence and reflection with the collection owners are established and its benefit in sharing past personal experience experiences is outlined. Finally, in a novel investigation with motivated third parties we demonstrate the opportunities such narrative accounts may have beyond the scope of the collection owner in: personal, societal and cultural explorations, artistic endeavours and as a generational heirloom
