The objectives of this clinical trial are to explore the feasibility of the eye-tracking interactive system in improving communication disorders among non-verbal ICU patients. It will also preliminarily investigate the effectiveness of this system in facilitating communication for these patients. Researchers will compare the eye-tracking interactive system with traditional augmentative and alternative communication (AAC) technologies (such as body language, writing boards, etc.) to observe the feasibility and preliminary effectiveness of the eye-tracking interactive system in improving communication disorders. Participants will: * Use augmentative and alternative communication technologies daily * Have detailed records of every communication interaction

The eye-tracking interactive interface designed based on evidence-based and co-design principles is installed on tablets or computers equipped with cameras, forming the eye-tracking interactive system.
Communication efficiency
Communication efficiency is defined as the number of correctly expressed needs per minute, calculated as the total number of correctly expressed needs divided by the duration in minutes. The aforementioned duration of assistive communication and total number of correctly expressed needs will be documented in the Communication Information Registration Form.
Time frame: up to 5 days after enrollment
Communication accuracy
Communication accuracy is calculated as the number of correctly expressed needs divided by the total number of expressed needs. The aforementioned total number of expressed needs and total number of correctly expressed needs will be documented in the Communication Information Registration Form.
Time frame: up to 5 days after enrollment
Patients' communication ability
The LCS (Loewenstein Communication Scale) will be used to assess patients' communication ability. This tool is primarily used in clinical practice to assess the communication abilities of minimally responsive patients. It comprises five hierarchical functions: mobility, respiration, visual responsiveness, auditory comprehension, and communication. Each function is divided into five parameters, with scores ranging from 0 to 4 (each function has a maximum score of 20, and the total score is 100).
Time frame: up to 5 days after enrollment
Nurses' compliance
The compliance of nurses is defined as the number of times nurses in the intervention group use the eye-tracking interactive system for assistive communication divided by the total number of communication interactions.
Time frame: through study completion, an average of 1 year
Time spent training patients during initial use
The research team is going to independently develop a Communication Information Registration Form, which is to include the duration of training provided by nurses to patients when they use the eye-tracking interactive system for the first time. After the completion of the intervention, the average training duration is to be calculated.
Time frame: Day 1
Incidence of delirium
The CAM-ICU (Confusion Assessment Method for the Intensive Care Unit) will be used to assess the occurrence of delirium.The CAM-ICU uses the CAM algorithm and has four features: (1) altered mental status/fluctuating course, (2) inattention, (3) altered level of consciousness, and (4) disorganized thinking. Like the CAM, a patient must be inattentive (cardinal feature of delirium) in order to be CAM-ICU positive.
Time frame: at 9:00 AM and 9:00 PM daily
Patient satisfaction
The PIADS (Psychosocial Impact of Assistive Devices Scale) will be used to measure the impact of assistive devices on patients and their satisfaction levels.This tool is a 26-item, self-report questionnaire designed to assess the effects of an assistive device on functional independence, well-being, and quality of life. Each item is rated on a 7-point Likert scale, ranging from -3 to +3. Higher scores generally indicate that the assistive device has a more positive impact on these aspects; conversely, lower scores suggest a less positive impact, or even potential negative effects.
Time frame: up to 5 days after enrollment
Patient enrollment rate
The patient enrollment rate is calculated as the number of patients who successfully meet the eligibility criteria and are enrolled in the study divided by the total number of patients screened for eligibility during the study period.
Time frame: through study completion, an average of 1 year
Patient withdrawal rate
The patient withdrawal rate is defined as the number of enrolled patients who discontinue study participation (for any reason) prior to the completion of the predefined study protocol (e.g., intervention course) divided by the total number of enrolled patients.
Time frame: through study completion, an average of 1 year
