THEA: A Technique for Human Error Assessment Early in Design
نویسندگان
چکیده
THEA is a technique designed for use by interactive system designers and engineers to help anticipate interaction failures. These may become problematic once designs become operational. The technique employs a cognitive error analysis based on an underlying model of human information processing. It is a highly structured approach, intended for use early in the development lifecycle as design concepts and requirements concerned with safety and usability – as well as functionality – are emerging. We believe the technique advances the systematic identification of human-computer interaction error through its straightforward application, requiring minimal formal knowledge of human factors or cognitive psychology.

THEA: Human Error Analysis for Requirements Definition
THEA is a technique developed to help designers in interactive systems (originally in the aviation domain, but hopefully applicable in other contexts) to anticipate interaction failures or “human errors” that may be problematic once their designs become operational. The techniques is intended for use early in the development lifecycle, as design concepts and requirements concerned with safety a...
متن کاملTHEA: Human Error Analysis for Design Evaluation
This report uses examples from two flight deck based case studies to illustrate how to use the THEA technique for carrying out a human error analysis during early design. The aim is that this document should accompany a one day tutorial and should be sufficient to capture the essence of the design method. This document introduces material that is an evolution of the THEA techniques and includes...

Background and Objectives: Despite contribution to catastrophic accidents, human errors have been generally ignored in the design of human-machine (HM) systems and the determination of the level of automation (LOA). This paper aims to develop a method to estimate the level of automation in the early stage of the design phase considering both human and machine performance. Methods: A quantita...

It is intended for use early in the development lifecycle as design concepts and requirements concerned with safety, usabi...
متن کاملIdentification and Evaluation of Human Errors in Low Voltage Distribution Systems using FUZZY-HEART Technique
Electricity-related occupational accidents are the fifth leading cause of occupational deaths. One of the major causes of occupational accidents is human error. That is why the human role as a cause of the accident is so important and must be considered during risk assessment. The purpose of this study is to present a Fuzzy-HERAT human error assessment method, which can be used to assess the pr...
