The role of expectations in human computer interactions by emanuel baisire

The research paper examines the role of expectations in human-computer interactions. The thrust of the paper was to understand how user interface designers can determine user expectations in order to create a positive experience in human-computer interactions. The study involved 70 undergraduate students randomly paired with either a computer or human partner to interact and execute assigned tasks. A human partner in the study refers to a face-to-face interaction with another individual working on one assignment whereas human-computer interaction involves an individual utilizing technology to perform a similar task. To understand the role of expectations in HCI, researchers viewed expectations in this case as a behavioral pattern. The study focused on expectation state theory (EST) and expectancy violation theory (EVT). Expectation state theory is based upon predisposed assumptions and characteristics about what a certain individual or group of people are able to achieve based on their social status, age and other demographic factors. EST theory states that people with socially acceptable positions or having a preferred status are accorded high expectations compared to their counterparts with undesired characteristics. Ideas from individuals with high expectations are given special considerations and are easily embraced compared to individuals characterized under a low expectations group. Expectancy violation theory (EVT) focuses on the extent to which expectations influence behaviors. It considers factors like individual characteristics, relationships and context. The study concluded that interactions with humans are more expected and widely regarded compared to computer interactions. The research also revealed that user interfaces that measure up to the expectations are highly rated and acceptable than those interfaces with low expectations. The research recommends that to design a

The research paper examines the role of expectations in human-computer interactions. The thrust of the paper was to understand how user interface designers can determine user expectations in order to create a positive experience in human-computer interactions. The study involved 70 undergraduate students randomly paired with either a computer or human partner to interact and execute assigned tasks. A human partner in the study refers to a face-to-face interaction with another individual working on one assignment whereas human-computer interaction involves an individual utilizing technology to perform a similar task. To understand the role of expectations in HCI, researchers viewed expectations in this case as a behavioral pattern.
The study focused on expectation state theory (EST) and expectancy violation theory (EVT). Expectation state theory is based upon predisposed assumptions and characteristics about what a certain individual or group of people are able to achieve based on their social status, age and other demographic factors. EST theory states that people with socially acceptable positions or having a preferred status are accorded high expectations compared to their counterparts with undesired characteristics. Ideas from individuals with high expectations are given special considerations and are easily embraced compared to individuals characterized under a low expectations group. Expectancy violation theory (EVT) focuses on the extent to which expectations influence behaviors. It considers factors like individual characteristics, relationships and context.
The study concluded that interactions with humans are more expected and widely regarded compared to computer interactions. The research also revealed that user interfaces that measure up to the expectations are highly rated and acceptable than those interfaces with low expectations. The research recommends that to design a desirable user interface, one need to consider technological features that meets a certain expectations threshold.
