Unsynchronized 4D Barcodes

We present a novel technique for optical data transfer between public displays and mobile devices based on unsynchronized 4D barcodes. We assume that no direct (electromagnetic or other) connection between the devices can exist. Time-multiplexed, 2D color barcodes are displayed on screens and recorded with camera equipped mobile phones. This allows to transmit information optically between both devices. Our approach maximizes the data throughput and the robustness of the barcode recognition, while no immediate synchronization exists. Although the transfer rate is much smaller than it can be achieved with electromagnetic techniques (e.g., Bluetooth or WiFi), we envision to apply such a technique wherever no direct connection is available. 4D barcodes can, for instance, be integrated into public web-pages, movie sequences or advertisement presentations, and they encode and transmit more information than possible with single 2D or 3D barcodes

Adopting Active Learning Classroom (ALC) Technology and Overcoming Barriers: A Faculty Development Intervention Model for Technology-Enhanced Learning Spaces

The goal of this study was to understand how instructors use technology, and what challenges they face, but also to increase the participants’ understanding of Active Learning Classroom (ALCs) technologies as it applies to their teaching by applying action research methodologies. This study also seeks to lay a foundation for additional research on ALCs, education technology, and the needs of instructors in terms of faculty development in technology. This study investigates a group of 13 faculty members in multiple disciplines teaching in ALCs. Thus far, research on the impact of technology-enriched learning environments like Active Learning Classrooms has typically centered around student learning (Beichner et al., 2007; Frazee, Hughes, & Frazee, 2014; Morrone, Ouimet, Siering, & Arthur, 2014). Less attention has been paid to the faculty development needed for instructors to properly take advantage of these environments The research study addresses three questions: First, how and, for what purposes, do faculty use technology in the ALC? Second, what technology adoption factors and barriers were experienced by instructors in an Active Learning Classroom? Third, using Kolb’s experiential learning theory (1984, 2014), how does a semester-long faculty development intervention program impact instructors’ adoption of Active Learning Classroom technologies? Results indicated that the most frequently used technologies were those that were familiar from traditional (technology-equipped) lecture spaces that faculty had used. Faculty were most comfortable with content delivery tools such as instructor laptops connected to the LCD TVs, the instructor podium, and whiteboards. Additionally, technology adoption factors and barriers to adoption were identified, including time, ease of use, equipment availability, institutional classroom support, peer support, and instructor comfort levels with technology and troubleshooting. Through action research, the newest Active Learning Classroom instructors received the most hands-on training on the classroom hardware during consultations, and the exposure to classroom technologies and troubleshooting tips via an experiential learning framework allowed them to better understand the podium interface, document camera and wall-buttons while having an opportunity to reflect on their teaching

Interaction Design: Foundations, Experiments

Interaction Design: Foundations, Experiments is the result of a series of projects, experiments and curricula aimed at investigating the foundations of interaction design in particular and design research in general. The first part of the book - Foundations - deals with foundational theoretical issues in interaction design. An analysis of two categorical mistakes -the empirical and interactive fallacies- forms a background to a discussion of interaction design as act design and of computational technology as material in design. The second part of the book - Experiments - describes a range of design methods, programs and examples that have been used to probe foundational issues through systematic questioning of what is given. Based on experimental design work such as Slow Technology, Abstract Information Displays, Design for Sound Hiders, Zero Expression Fashion, and IT+Textiles, this section also explores how design experiments can play a central role when developing new design theory

Resource Use and Water Implications of Material Consumption in Consumer Electronics

Rapid technological innovation has introduced a broad spectrum of materials in the consumer electronics sector. Consumption of these materials increases the demand for water and potentially discharge contaminants into the water resources across their life cycle, exacerbating freshwater scarcity and pollution. These water impacts have not yet been fully studied, as most literature on consumer electronics focuses on supply chain energy, carbon footprint, or end of life management. Evaluating water impacts requires data on material content, life cycle water consumption and emissions at spatial level, and availability of impact assessment models that connects life cycle data to water impacts. Data on these aspects are available at varied degrees for different materials used in the electronics. This research created data on materials used in consumer electronics and studied implications on water resources for two major material categories - metals and plastics. Bill of materials (BOMs) data were created for 95 unique consumer electronic products that contain information on mass of major materials and components. Then, life cycle water impacts associated with extraction and production of metals found in consumer electronics are evaluated to identify material hotspots for future improvement. Water impacts were analyzed for individual metals and then for the representative metal profile of case study products (smartphones and laptop computers). Finally, profile of polymers and additives in the e-waste is created to understand linkage to water impacts as well to evaluate implications to establishing e-plastics circular systems. Results indicate that, on the individual material level, precious metals have the highest water impacts in their supply chain. Water scarcity impact is mainly because of water consumed directly for mining operations and indirectly for energy production, and water degradation attributed to metal emissions during mine tailings management. The geographical region where metal production happens is also a contributing factor to water impacts, as water stress varies spatially. Therefore, sourcing metals from regions with lower water stress is an opportunity to reduce supply chain water impacts. At product level, precious metals have the highest contribution per smartphone, whereas aluminum has the highest contribution per laptop. Product design changes, such as use of recycled metal or using a low impact metal are observed to reduce water impacts. Further, e-waste shows a diverse mix of polymers and additives, including flame retardants, pigments, and heavy metals that can potentially pollute water resources if released. As a result, transition to circular systems is important to keep the plastics from entering the environment. To enable this transition, multistakeholder engagement in the electronics sector is required to make an informed decisions in product design, policy planning and material recovery infrastructure

Internet of Things-Based Fire Alarm Navigation System: A Fire-Rescue Department Perspective

In the past few years, fire alarm systems have become increasingly sophisticated and more capable and reliable. The two main objectives are the protection of life and property. As a result of state and local codes, fire protection has become more concerned with life safety over the past two decades. Several safety measures have been implemented to address the problems caused by the fires and reduce the number of fatalities and property damage. Our project is to develop and review a fire alarm navigation system and application that uses the internet of things. Fire alarm systems are designed to warn people about fires in advance so that they can evacuate the fire-affected area and take immediate action to control the fire. There will be a GPS module, a flame sensor, a smoke sensor, buzzers, LEDs, and a GSM module to ensure early notification to authorities and fire stations. The aim is to reduce the loss of lives and property. A questionnaire was designed to conduct a brief survey in a multinational sports production company in Sialkot, Pakistan, regarding the IoT fire alarm navigation system. Besides installing the system in the factory, we compare the results with fire incident response time with and without this system at rescue 1122 fire head station.publishedVersio
