Extending Perceived Navigational Risk and Technology Acceptance Model to Electronic Chart Display and Information System
Authors: ,
Abstract: Seafarers’ doubting about the electronic chart display and information system is a widespread problem. To better explain, predict, and increase user acceptance, this research focused on the impact of navigational risks to address and predict shipmates’ computer acceptance by a measure of their intentions, attitudes, perceived usefulness, and perceived ease of use. Thus a hypothesized model was proposed to examine the relationships between the related constructs by comparing experienced shipmates with non-experienced marine college students. Study verified that the perceived navigational risk had negative effect on perceived usefulness and perceived ease of use, and also indicated its further influence on the perception on technology acceptance. These results may provide important references for manufacturers and marine college to adjust further products, or enhance the training course on information literacy and the ability of manipulating modern navigational information system.
