The Use of Smart Glasses for Environmental Controls

Not Applicable

Completed

• Conditions: Neurologic Disorder

• Registration Number: NCT06932978
• Lead Sponsor: NHS Lothian

Brief Summary

Environmental control systems are a type of assistive technology that can be controlled by a wide variety of different methods (e.g. switches) and can assist people with physical disabilities to control various electronic devices in the home. Communication aids are designed to assist people who have difficulties speaking to communicate. Both systems are designed to provide independence and potentially could have a positive effect on quality of life.

The majority of communication aid and environmental control systems aimed at high end users require a screen to be mounted in front of the user. The limitations with this are that the user is only able to access their device when it has been suitably mounted in front of them. There are occasions when mounting devices in front of the user is difficult due to other considerations for example transfers in and out of a wheelchair. As smart glasses can potentially be worn at all times during the day this could provide an effective alternative solution.

The purpose of this study is to explore with service users the usability and satisfaction provided by smart glasses when operating a communication aid/environmental control system. The study will achieve the above aim by undertaking a satisfaction questionnaire prior and post a 3 week trial of using smart glasses with their device. In addition an interview will be carried out with participants to explore the impact that smart glasses has had on the usability of their device.

Participants will be recruited by contacting eligible patients of the NHS Lothian Environmental Control Service and communication aid service. The end point of the study will be 8 months from the start date (allowing for follow up data to be collected for anyone recruited towards the end of the 6-month recruitment period).

Primary Outcome Measures

Name	Time	Method
Quest 2.0	Baseline and 3 weeks	This is a 12-item instrument that asks for the recipient to score their satisfaction of various aspects of an assistive technology device and service between 1 (not satisfied at all) and 5 (very satisfied). Eight of items relate to a device and four to the service, in this study due to the focus on the assistive technology device, only the answers relating to the device were collected. The instrument has been extensively used for assessing satisfaction with assistive technology and has been validated and tested for its reliability.

Secondary Outcome Measures

Name	Time	Method
Semi-structured interview	3 weeks after provision of smart glasses	The semi-structured interviews were conducted using six open-ended questions. The questions posed included ones relating to both satisfaction and usability. This included ones about the advantages, disadvantages and any points for improvement for the smart glasses. Additional questions included ones about making comparisons to using a traditional screen setup, how easy or hard the smart glasses were to use and whether participants would continue to use the smart glasses. When appropriate follow up questions were asked to elicit more information about answers.
