No the definition is the same, just more specific in software.
Here is the definition of software ergonomics (soft ergonomics) which is clearly in line with the general definition:
Soft ergonomics is the study of designing virtual interfaces that cater towards the wellness of the human body, its emotional and cognitive abilities.
Soft ergonomics is a subset of ergonomics and human factors engineering, a larger body of the study of human abilities for designing equipment and devices that fit the human body. Soft ergonomics can be thus defined as the ability of any virtual interface(computer application, website, ATM options, parking meter etc.) to make it comfortable for the user to use the interface while working on the user's request.
