Method and System for Controlling an Indoor Ambient Environment for a Patient with Different Light and Sound Needs

Patients with neurodegenerative disease expressed a range of affective signals , even till very late stages. For example, one third of last-stage dementia patients expressed sadness at the departure of relatives. Many of the emotions are influenced by environment. For example, 20% of people with Alzheimer's experience "sundowning". Seasonal Affective Disorder (SAD) is a type of depression that typically occurs each year during fall and winter. A wide range of disorders can be affected by visual or audio sensitivity.

Disclosed is a method and system for adjusting an indoor audiovisual ambient environment for a patient with different light and sound needs . The method and system controls the light and sound needs by adding control to an indoor ambient environment , leveraging the awareness of patient conditions as illustrated in the figure .

The method and system senses an ambient environment . A variety of inputs are used to activate the system. The changes in intensity and timing of light for Seasonal

Affective Disorder (SAD) can be detected. A photodiode can be placed as a skylight. Different levels of voltage or ranges are converted to discrete levels . A mapping function maps the levels into disease-specific presets and user-specific settings. Photovoltaic sensor arrays can be used to improve detection . Besides the intensity of

light, wavelength, rapid flickers, and seasonable timing can also be detected . The method and system can further detect input from multiple sources such as , but not limited to, sound amplitude, wave frequency, pressure or wavelength. The method and system can also be activated by a trigger such as, but not limited to, family members or care givers leaving or changes in season or daylight. Additionally, the method and system can detect changes in emotional and physical status of the patient via mobile monitoring devices or interactive questions.

Thereafter, the method and system determines a target ambient environment per disease. The method and system provides settings for various diseases and conditions. For Alzheimer's disease, the light settings keep the room well lit in the evening from sundown to bedtime. An adequate lighting reduces agitation that occurs

when surroundings are dark or unfamiliar for patients with Alzheimer's . The method and system retrieves a list of preset patient preferences such as , but not limited to, a favorite color, smell or fragrance, sounds of music or family members, books, news, paintings photos, movies and games. The patient preferences information can be collected in advance from both patient or family members and care givers . The method and system can decide most suitable ambient settings based on interaction with patients or family members. The suitable ambience settings comfort the patient and redirect the attention of the pa...
