Evaluation of Technology Enhanced Accessible Interaction Framework and Method for Local Thai Museums

Abstract

A Technology Enhanced Interaction Framework (TEIF) and method for enhancing interactions with people, technology, and objects was developed and successfully validated by three developer experts, three accessibility experts, and an HCI professor. The TEIF main components are people, objects,technology, interactions and communications, time/place, context, and interaction layers while the TEIF method involves requirement questions with multiple choice answers and technology suggestions, Interaction Diagrams and Use Case Diagrams. For evaluation of the TEIF method, an example involving a hearing impaired visitor to a Thai small local museum was developed. An experiment with 36 developers showed they were able to use the TEIF ethod to evaluate requirements for technology solutions to problems involving interaction with hearing impaired people better than the Other Methods. The TEIF method helped developers significantly select a best solution more than other methods and significantly rate the best solution closer to expert ratings than the other methods. Questionnaire results showed that the TEIF method helped to evaluate requirements and technology solutions to interaction problems involving hearing impaired people and would also help with gathering requirements and designing technology solutions for people with other disabilities.
