  3. Various Supporting Plans
Various kinds of support will be possible using assistance dogs who are mounted with the above devices. We, therefore, classified support plans into eight categories. Additionally, most individuals with dementia cannot manipulate these devices, so the booting of the devices needs to be automatic. Therefore, volunteers or caregivers should set the time schedule for booting. They are also required to maintain the devices and to check caring circumstances and health conditions of dog.

1) Relaxation support: A dog by itself can provide relaxation to individuals with dementia (owner) through their fur, gestures, and expressions. Furthermore, dogs mounted with the above devices should be trained to go to owners when an alarm sounds from the IC recorder, or when other devices emit sounds at a set time [6]. Dogs will then be trained to show owners content, such as music, photos, or reminiscence videos [7, 8]. Owners can then enjoy listening or watching to this content, leading to their further relaxation.

2) Scheduling support: By mounting IC recorders and other voice output devices, recorded messages or video instructions [9] can be played to prompt an individual’s daily activities, such as taking medication, eating breakfast, and so forth. When an alarm or word is emitted, the trained dogs go to their owners and show the messages or video instruction through the devices. Preceding these presentations, automatic outputs of music are also desirable to raise motivation to accomplish given tasks [7]. Medicine and water prepared in the bag are conveyed by the dog when an alarm sounds along with the message output to “take medicine”. The dog will be trained to deliver a note pad and pencil when alarm and message “take memo” are emitted.
By listening to subsequent alarms, dogs will routinely go to their owner to confirm whether the owner has finished the task or not. If the task was completed, the dog requires the owner to push a button on a PC mounted on their body. Then, a “completed” sign will appear on the schedule note on the PC monitor, and a sound or message praising the owner’s accomplishment will play. This scheduled table should be shown regularly to owners by the dog to remind them of remaining tasks.
Individuals often fail to execute particular tasks, such as operating an electronic oven or washing machine, in the same way each time. When the time comes to execute the task, an alarm is emitted. A dog will be trained to goes to a user and show them an appropriate auditory or video reminder of how to use a given device. For this purpose, an approach sensor is also set to work. When the individual approaches a location to do certain tasks, an alarm is automatically emitted to invite the dog over.
When an owner is reluctant to do a certain task, for example to prepare meals or get up from bed, the trained dog will touch on the owner to motivate them to do the given task. For example, if individuals with severe dementia cannot find the bathroom, even in their home, regular and intermittent alarms or words would be emitted and the dog would touch and escort the owner to the bathroom..
In order to execute these various tasks, dogs should be trained to behave in response to different alarms or words. For example, alarm A would signal for a dog to bring medicine, alarm B would indicate that their owner needs help navigating their way to the bathroom.

3) Communication support: Individuals with dementia ask the same questions repeatedly, such as “What day is it today?”, “Shall I go to the hospital today?” In order to deal with these questions, trained dogs will know to go to owners when an alarm or word is emitted intermittently and to give information regarding what an individual wants to know before they ask. Recently, automatic question-and-answer systems using smart phones have been developed. These systems should be incorporated.
In order to help individuals with dementia converse with remote caregivers and volunteers [9], small computers and cameras with Internet connections need to be mounted on to dogs. When an alarm or word is emitted by the remote volunteer, the trained dog will go to owners to start a remote conversation with the volunteer; similarly, a dog will be able to escort their owner to a certain room in the home where devices for conversations are setup. When there are no volunteers to talk to, the free-talking system with the anime agent [12] can be used. This system starts on set times, or an individual’s verbal agreement to talk in response to an automatic recommendation is given by the dog, such as “Do you want to talk with the agent?”

4) Recording support: Individuals with dementia often forget the meals they ate, the content of conversations, locations of objects, and so forth. Therefore, a recording and finding system for behaviors and objects can be mounted to a dog to help with daily routines [10]. When an alarm is emitted regularly, the dog goes to their owner and asks what the owner has just talked about, eaten, or what task has been done. The individual’s replies are recorded, which will be automatically analyzed by speech recognition software. The dog should be trained to sleep near the automatic transmitting data system in order to transfer the recorded data to a computer and the Internet. Later, a caregiver who is living away from the patient’s home can check the recorded content via the Internet.
For individuals with severe dementia, a dog can be trained to remain at the owner’s side while recording the owner’s behavior all day [10]. When the owner searches for objects, a caregiver may replay the video and search for the objects, even remotely.
When a dog meets an unknown person or sound, they can be trained to bark at them, which automatically starts recording of cameras and microphones. These recordings will also be transmitted to remote caregivers.

5) Danger detection support: Certain abnormal changes in the environment, such as smells, heat, smoke, etc. can be noticed by an assistance dog. The dog will be trained to go to the owner. As for the observation of owner’s safety, alarms are emitted at regular intervals. At each time, the dog will know to search for their owner, and will require owners to touch a monitor on the dog. This touching is transmitted to a caregiver as a safety signal. If no signals were sent, caregivers will confirm the owner’s safety through the camera on the dog’s shoulder or head.
Individuals with dementia so often become confused in the evening and want to return to their “home”. When an owner steps on a mat near the exit of their home, an alarm sound is emitted. The dog will then rush to this spot, showing previously prepared messages from a caregiver to the owner.

6) Searching support: Caregiver or volunteer paints some smelling on objects by such as aroma. When owner lost the object, same smelling is sniffed to the dog. The dog will search it, and may bring it back. If possible, the word “key” makes the dog search key on the base of previous combination of “key” and its smell.
The GPS sensor is attached to the dog. If the owner lose his/her way outside, the dog is also expected to bring the individual to home.

7) Group activity support: Dog can accomplish role as pet dog also in the institution. Furthermore, each institutionalized individual are attached with electronic tags, on which special messages for each individual are recorded. When the dog with a reader for the tags approaches to an individual, the special messages are emitted to the individual like “Hollow, Mr. Yasuda, how about your ache on the back?”
When group conversations, such as reminiscence discussions, are held in institutions, the anime agent of the free-talking system can play the role of chair person through the dog.

8) Future support: When an owner gets angry, or shouts loudly, sound sensors on the dog recognize the owner’s agitation. The dog then goes to the owner and presents content designed to make the owner calm.
If individuals with dementia are searching for something or moving restlessly, a recognition system for behavior using facial or 3D posture analyzers will begin and order the dog to go to the owner and execute Q and A questions to resolve the owner’s worries.
