Individual evaluation toward technology may influence adoption or usage of a new technology particularly instant messaging applications on smartphones. Davis (1989) introduced two main concepts that explain people’s usage and rejection of a technology; perceived ease of use and perceived usefulness.  Perceived is an important factor to develop intention to use, to motivate, to affect, to predict, to explain, and to increase technology acceptance. As a concept, perceived also grows based on various contexts such as perceived usability, perceived enjoyment, perceived quality, perceived aesthetic, and perceived expressiveness. Those concepts were used to analyze information and communication technology acceptance particularly electronic mail (e-mail), mobile social games, social networking sites, and mobile apps. This article discusses elaboration of perceived as a main concept to explain instant messaging applications use. By applying a quasi-experiment, this article analyze the confirmation factors of perceived instant messaging application use. This article reveals that perceived could be elaborate into main concepts of instant messaging applications use from psychological motives.
