A computing device that enables user interaction when the user is in a mentally debilitating state includes a memory configured to store electroencephalogram (EEG) waveform signals. The EEG waveform signals are generated by associated recognition data. Response data is generated based on the associated recognition data and stored in memory. An input component is configured to receive an EEG waveform signal from a user. A processor is configured to compare the received EEG waveform signal with the stored EEG waveform signals to determine if the received EEG waveform signal matches a stored EEG waveform signal. An output component is configured to automatically output the response data generated by the associated recognition data based on the determination from the processor.本發明係關於一種可使處於心智衰退狀態的使用者進行互動的計算裝置，其包括一經配置以儲存腦波圖(EEG)波形信號的記憶體。EEG波形信號係由相關的識别數據產生。基於相關的識别數據產生反應數據並儲存於記憶體中。配置一輸入組件以接收來自使用者的EEG波形信號。配置一處理器以比較接收的EEG波形信號與儲存的EEG波形信號，以確定接收的EEG波形信號與儲存的EEG波形信號是否匹配。配置一輸出組件以自動輸出基於處理器之確定而由相關識别數據產生的反應數據。
