Developing ISO 9241-151 product certification process: Challenges

ISO 9241 Ergonomics of Human-System Interaction Standard, which is also called as Ergonomic requirements for office work with visual display terminals, is a standard containing many parts about ergonomics of human computer interaction. In this paper, we aim to elaborate the challenges evoked during ISO 9241-151 Product Certification Process handled at the Middle East Technical University (METU), Human Computer Interaction Research and Application Laboratory (METU-HCI-LAB), which is the first and only accredited laboratory of Turkish Standards Institute-TSE within the scope of “TS EN ISO/IEC 9241-151”.

This paper presents a detailed SIMULINK model for a conventional capacitive Sigma-Delta accelerometer system consisting of a MEMS accelerometer, closed-loop readout electronics, and signal processing units (e. g. decimation filters). By using this model, it is possible to estimate the performance of the full system, including the effect of individual noise components, operation range, scale factor, etc. The model has been verified through test results using a lateral accelerometer, full-custom designed 2nd-...
Design of a complex modulus test system for viscoelastic materials.
Erdoğan, Bilgeha; Özgen, Gökhan O..; Department of Mechanical Engineering (2019)
In this thesis, the design of test devices for dynamic characterization of elastomer materials and elastomer vibration control components are designed. For this purpose, two different studies are conducted. In the first study, an already installed test setup is modified to provide preloading capability. In the second study, a completely new test setup is established. Conceptual design studies are carried out based on the information obtained in the literature and related standards, then the validity of the ...
Evaluation of UAS Camera Operator Interfaces in a Simulated Task Environment An Optical Brain Imaging Approach
Çakır, Murat Perit; Akay, Daryal; Ayaz, Hasan; İşler, Veysi (null; 2012-07-11)
In this paper we focus on the effect of different interface designs on the performance and cognitive workload of sensor operators (SO) during a target detection task in a simulated environment. Functional near-infrared (fNIR) spectroscopy is used to investigate whether there is a relationship between target detection performance across three SO interfaces and brain activation data obtained from the subjects’ prefrontal cortices that are associated with relevant higher-order cognitive functions such as atten...
A measurement framework for component oriented software systems
Salman, Nael; Doğru, Ali Hikmet; Department of Computer Engineering (2006)
A measurement framework is presented for component oriented (CO) software systems. Fundamental concepts in component orientation are defined. The factors that influence CO systems’ structural complexity are identified. Metrics quantifying and characterizing these factors are defined. A set of properties that a CO complexity metric must satisfy are defined. Metrics are evaluated first using the set of properties defined in this thesis and also using the set of properties defined by Tian and Zelkowitz in [84]...
Investigation of the effects of structural characteristics of object-oriented software on fault-proneness
Gölcük, Halit; Bilgen, Semih; Department of Electrical and Electronics Engineering (2014)
This study investigates the effects of structural characteristics of object-oriented software, which are observable at the model level of the software developed by means of Unified Modeling Language (UML), on software quality, assessing quality in terms of fault-proneness. In the scope of this thesis study, real-time embedded software components developed by Aselsan, a leading defense industry company in Turkey, were analyzed. The correlation between software metrics measured from the UML models of the soft...
