For example, in order to stimulate the visual sense a MSE may contain fiber optic lights and bubble tubes with sheets of cascading colored light that is reflected throughout the room.  They may have curtains of these fiber optics that encourage touch, with soft and safe strands that can be programmed to change color on command.  Some of these fiber optics actually respond to the touch, and some are operated by a switch.  Projectors are a common addition to cast light through special effect wheels, creating ever changing patterns that mesmerize and soothe.  Both the child and the geriatric patient can enjoy watching the play of light for hours, and be either calmed or focused by it.  Bubble walls and bubble blowing fans are also great ways of capturing the attention and incorporating touch.

                         

The introduction of a pleasing scent into the room, also known as aromatherapy, can be a rewarding stimulation with switch operated fans.  Sensory fountains that create a soft mist through ultrasonic vibration can work with essential oils to bring a gentle cloud-like vapor that pours from a small bowl.  Devices of this nature should be used with caution due to their construction of glass and electrical components.  Always choose the scents carefully, and avoid anything "too strong" or overwhelming.  Because essential oils are easily absorbed into the skin, direct contact with them without dilution is not advised. 

                   

Tactile sensation is often addressed in these rooms through interesting or unusual textures.  You may have seen "squishy balls" that are filled with gel or covered with soft nubs, as well as soft spiky balls with long stretchable fingers.  Vibrating chairs, cushions or toys promote a feeling of massage and relaxation as well.  Hairbrushes that are designed to stimulate the scalp may be used, along with soma acoustic pillows that combine both vibration and sound.  Walls can be covered with textured panels in these rooms, to both protect and delight.

                                         

Three-dimensional spaces inside a MSE like tunnels, tents, corners and tubs can be used to "hide" in and promote security.  They can also give shelter from sound and light, further relaxing the user.  Crawl tubes and tunnels may offer an extra reward of accomplishment and sensory deprivation.  These are often soft, padded, lightweight units that can be easily moved and adapted for the patient.  Ball pools are a fun way to introduce tactile stimulation through play.  Some pools include lighting, vibration and sound, further increasing awareness of the occupant.  Weighted items like scarves and blankets have also been used to calm and heighten focus through propioceptive feedback and stability.
