A control method includes acquiring time information including a wake-up set time; acquiring a sleep state of a sleeper who is stimulated by a stimulation device; determining a change of the sleep state; causing the stimulation device to start increasing a stimulus which urges the sleeper to awake at a control start time as time before the wake-up set time by a predetermined time period; and controlling a change amount of the stimulus based on the change of the sleep state with the stimulus.

The digital command prompting device for dementia patients using augmented reality is an aid is to help all people, especially those who have special needs particularly individuals who have diminished or diminishing function of their brain. The device is predominately mobile but can also be stationary and can be programmed by receiving and selecting pre-set commands to operate and assist a user with their daily living standards or needs but is particularly adapted for use when a user is having a disorientation episode as to place and time. The device also has other various features including an illuminated display panel, a GPS tracking capability, an alarm, an illumination element, solar panel and battery backup components, time and date clocks, is provided water resistance covers and/or material, among other things. The device may be used within the home environment, outdoor environment or a restricted environment, e.g. aged care facility, hospital, pre-school or school.

The mobile vibrating alarm system may be used to wake a person by producing vibrations for a selected period of time. The mobile vibrating alarm system includes a vibration unit having a vibration motor, a wireless receiver, and a controller. The controller transmits actuation signals to the vibration motor such that the vibration motor is driven to activate for a selected period of time. At least one parameter of the vibration motor may be varied at regular intervals, such as the frequency of vibration, the intensity of vibration, or a combination thereof. The mobile vibrating alarm system further includes a mobile communication device, which includes a wireless transmitter for transmitting wireless signals to the wireless receiver of the vibration unit.
