Resolving User Conflicts in Multi-user Context-aware Home Environment

Context-awareness is an enabling technology of pervasive computing that allows applications to adapt themselves in responseto contexts (e.g. activity, location, temperature level, etc.). However, an issue of user conflicts in context-aware applicationsmay arise when multiple users want to access the same application. Our research focuses on this issue and proposes aconflict resolution approach that resolves the conflicts in context-aware home applications. The proposed approach takes intoconsideration the users’ special case contexts (e.g. illness of user) along with their priorities and preferences. The proposedapproach is also useful in cases where multiple users with multiple special cases try to access one application or service.To show the usefulness of the proposed approach, we have integrated the proposed conflict manager with the UbiREAL, asimulated context-aware home environment. The conflict manager utilizes different strategies and different approaches toresolve user conflicts according to the involved situation to suit the need of the family. The prototype evaluation shows thatthe users are satisfied with the proposed system and suggests that the use of users’ special case contexts in detecting andresolving the user conflicts is essential and necessary in the context-aware smart home environments.

An Indoor Navigation Support for the Student Halls of Residence using Augmented Reality: A Design Perspective

Augmented Reality (AR) technology has become increasingly popular due to its potential use in an indoor environment. AR technology enables virtual information, such as navigation instructions, to be merged into the actual environment via a mobile screen. Using an AR-based Indoor Navigation speeds uptime while also being interactive in searching for a particular building location. Every year when new semester students enrol in the university, some students will have difficulty finding a particular location on the campus. The most searched for building upon arrival at the university is the student halls of residence. While searching for it, students waste time asking others for information or looking for a nearby campus map. Therefore, this project investigates the requirements needed for an AR-based indoor navigation application to be applied within the student halls of residence and identifies technical issues through a small-scale prototype development within a small navigational area. Seventy-one students participated in the feasibility study by responding to a set of questionnaires related to the Student Residence AR indoor navigation application. At the same time, four users with and without previous experience with AR applications evaluated the prototype application. The results identified that the more the students have difficulty searching, the more they require additional time to reach their destination and seek help from others, an excellent reason to implement the Student Residence AR indoor navigation. In addition, the prototype evaluation results discussed issues related to arrow path confusion, distance accuracy, assistive guideline, and software development challenges in AR development that could be beneficial to future developers and researchers.

Ergonomic Evaluation on Chicken Feeder Tool at Egg-Laying Chicken Farm SME

This research aims to evaluate the egg-laying chicken feeder that was designed at egg-laying chicken farm small and medium enterprise (SME). The main reason of this tool design was due to the worker’s complain of feeling pain during the feeding process. Evaluation was performed based on Nordic Body Map questionnaire result, physiological workload, and NIOSH lifting equation calculation. The observed work ranged from the feed filling in the basket until all feeds were distributed. The results showed that the %CVL was in the range of 18%-30% and the energy consumption of workers was in the range of 1.24-3.00 Kcal/minute. Thus, physiologically, the work activities carried out by the feed workers were categorized as very light workload. Meanwhile, evaluation using Lifting Index (LI) methods in the process of feeding showed the LI value ranged from 0.9-1, therefore this activity is safe to perform manually. Based on the prototype evaluation on the feeding aid, the process of feeding activities was more effective 1.5 times faster than the old tools. In addition, with the use of this new tool, the feeding process was easier to adjust the dose each time.

Development of prototype electronic dashboard service performance of LPKA class I Palembang

LPKA Palembang provides services to the community in the form of coaching in the fields of education, skills training, community guidance, and alleviation, services for Andikpas visits and complaints, remission submission services, assimilation, and other submissions especially to support alleviation programs such as the Conditional Leave (CB) program, Leaving Towards Free (CMB), and Parole (PB). To provide the best convenience and quality in providing services, a system is needed that can not only be used to submit and process service data online, but also can integrate service data so that it can be more easily accessed anytime and anywhere. The system created is an electronic dashboard or e-dashboard that can present data visually so that it is easily understood by readers. This study aims to build a prototype that can provide an overview of the e-dashboard system to be built. From the prototype evaluation, user feedback can be obtained which can be used to build an actual e-dashboard system so that it can reduce deviations from the system being built. The stages in this research are planning, designing, building, and evaluating the prototype. The results of this study are the development of e-Dashboard prototype that had been tested by 80% of LPKA Class I Palembang employees. The developed prototype has features that almost meet user needs because the system development is based on a quick analysis of the needs of future e-Dashboard users.
