THE HUMAN-COMPUTER INTERACTION BENEFITS
The human race rarely uses fixed associations between content or meaning and its physical representation. Instead, people encode the meaning into a form appropriate for the situation and purpose of the communication. Communication can be encoded using different ontologies such as different languages and terminology. Communication is thus able to take different physical channels (e.g., sound through the air, or writing on paper), all of which attempt to ensure that the content or meaning is communicated between the parties in the most accurate and efficient manner available for the specific characteristics of the situation. Currently, this is not the case with computer interfaces; contemporary interfaces instead tend to adopt a “one size fits all” approach for the majority of the interface.In taking this one-size-fits-all approach, content and meaning may not be transmitted to the user in the most accurate form, if it is communicated at all. The characteristics of the situation and participants are not taken into account. This makes the interface harder to use than might be, if it can be used at all. Some users, such as those with a sensory disability or those with a different native language, may not be able to access the information as it has been encoded using an inaccessible physical form (e.g., visual stimuli are inaccessible for the blind). Or it has been encoded using a foreign language, which the user does not understand. This immediately prevents the user from accessing the content and meaning conveyed by that form of presentation.
