The fifth-generation mobile network (5G) will soon become popular, and data utilization will increase. Although there is a large volume of video data, making it difficult to manage and use such data in our daily lives, there is huge potential with such data. We now often take photos using smartphones, but in future recording our lives by wearing video cameras would become popular. Since such data have a large amount of information, a video lifelog retrieval system is necessary. Although many studies on video retrieval have been conducted on some domains, e.g. TV programs, movies and so on, there have been few conducted on lifelogs. One of the main differences between them is regarding user queries and the fact that our memories are often ambiguous. We propose a video lifelog retrieval system that takes advantage of ambiguous search queries. We discuss the effectiveness of our system from our evaluation involving our own lifelog data we collected. We also discuss the characteristics of lifelog data and problems of our system.

DevOps is usually an industry approach that is practiced by seasoned and experienced programmers and developers. In most university settings especially in the Philippine context, DevOps is not usually part of the curriculum and in some cases are only introduced to learner programmers as an elective or as bonus material. We refer to these students in computing degree programs starting out in learning programming, as novice programmers. Upon graduation, these developers transition into industry roles where they are expected to be familiar with DevOps practices [18]. In most cases, they are not prepared, and fortunately, a great number of them are given training before fully transitioning into their hired roles. In this paper, we attempt to discover and design an intervention mechanism that can assist and prepare novice programmers to easily learn DevOps at an early stage. We gathered data and insights from novice programmers and inquired into their pains and struggles in learning and practicing DevOps. To help them in this process, we propose Grit, a prototype tool to support novice programmers in integrating DevOps. Initial insights provided affordances and design elements for a version control prototype with targetted intervention features. In the long run we intend to discover more insights involving the other stages in DevOps beyond version control.

Comments on the news articles can affect people's perceptions and behaviors. However, little is known about how people determine the degree of bias (DoB) of comments on political news articles. To address such bias issues, current platforms of news articles offer criteria to sort multiple comments on the news articles. However, little is known about whether the DoB of comments is reduced when publishers offer various criteria for sorting comments. We conducted surveys to identify how people determine DoB of comments on the news article, and how bias varies depending on how comments are sorted. The findings of this study revealed that there was a significant difference among the DoB by comments. Future work remains to develop an algorithm generating unbiased comments by using existing comments on political news articles and their DoB.

Despite numerous solutions offered, offline shopping experience for people with visual impairments (PVI) does not seem to improve much. A lot of PVI have not only visually but also economically challenging. However, existing solutions need additional devices or do not help them shopping economically. Therefore, the goal of this research was to develop a system that helps PVI go offline shopping conveniently and economically. We conducted qualitative surveys and interviews with eight PVI. Based on the identified challenges, we proposed opportunities for easy and economical offline shopping. We hope the findings of this study contribute to a deeper understanding of the offline shopping experiences of PVI.

Encouraging patients with cardiovascular disease to be more active is one of the critical challenges in conventional rehabilitation programs. Rehabilitation programs are mostly offered at specific times and locations (e.g., clinical facilities or in-home exercise programs), which are the root causes of participation barriers. We envision that use of mobile and wearable technologies can overcome such spatial/temporal restrictions and offer novel opportunities for promoting physical activities in their everyday lives. In this work, we introduce BeActive, a mobile-based intervention platform that delivers just-in-time intervention messages to help patients to be more active in their daily lives. The key innovation of BeActive is to leverage fine-grained tracking of user behaviors to deliver just-in-time feedback and to incentivize health behavior maintenance via micro financial rewards. To show the feasibility of BeActive, we conducted a preliminary study for seven days (n=5), and presented several design improvements for just-in-time health intervention.
