Inclusivity: The PTPI
The RUX Lab conducts research on perceptions of inclusivity of technology products. By studying these perspectives, we can gain insight as to if there is equitable access or use of these products, and help inform design for a diverse set of users.
​
One way we measure perceptions of technology product inclusivity is with the psychometrically validated Perceptions of Technology Product Inclusivity scale (PTPI). The PTPI can be used with any type of technology product to assess users' perceptions of its inclusivity.

The Perceptions of Technology Product Inclusivity (PTPI) Scale
The Perceptions of Technology Product Inclusivity (PTPI) scale is a psychometrically validated and comprehensive assessment instrument with five subscales. It was developed and validated based on the assessment of over 25 categories of technology products, thus can be applied to a wide range of products. The PTPI was developed with the intent of equipping technology product designers with the means to evaluate and enhance inclusivity across various products, contributing to the advancement of user-centric design and the creation of more inclusive technology experiences.
​
The PTPI is made of 25 questions, all are on a 7 point Likert scale from Strongly Disagree to Strongly Agree.
​Example Statements:
-
“I have a sense of belonging when I use this product.”
-
“I feel like the company considered the needs of customers like me when designing this product.”
-
“It is easy for me to learn how to use this product.”
-
“There is a good fit between what this product offers me and what I am looking for in this product.”
Applications of the PTPI
The PTPI has been validated with people with disabilities, to ensure that the scale accurately assesses their experiences with technology products.
