Only the abstracts seem to be in English but you can get a general idea of what's about.
I'm probably over-simplifying this (and I could be wrong), but from what I understand they are using various sensors/inputs (mic, camera, balance board) to acquire information about the user (pulse, weight, etc) and the environment (temp/humidity), and use that information to somehow generate a QOL "score".
The following three were filed on 10/29/2014:
WIPO Patent Application WO/2015/107747
This information processing system comprises a portable terminal. The portable terminal detects sensor information for assessing a user's emotions. It would be permissible, as an example, for the sensor information to be sound information which is detected by a microphone, or image information which is captured by a camera. The information processing system assesses the user's emotions on the basis of the sensor information. The portable terminal detects the sensor information in a period when the said portable terminal is in a standby state. As an example, the said standby state is a state wherein a display of the portable terminal is off.
A docking station (with a small projector?) for what device? Nintendo's next handheld or somehow compatible with a wider range of mobile phones? Is a universal docking station even possible? (Android/iPhone)
WIPO Patent Application WO/2015/107746
This display system is provided with a sensor, a projector, and a control means. The sensor detects user information for calculating a state relating to sleep of a user. The user information is, for instance, biological information, such as pulse rate. The projector displays, by means of projection, a predetermined image. For instance, the projector displays, by means of projection, an image on a ceiling by projecting the image upward. The control means controls the projector corresponding to the sleep-related state calculated on the basis of the user information.
WIPO Patent Application WO/2015/107681
A terminal system acquires physiological information from a user and transmits transmission information to a server system, said transmission information including the physiological information and/or health information relating to the health or the body of the user, obtained from said physiological information. The server system associates the transmission information received from each terminal system, and/or information obtained from said transmission information, with the user, and stores these as stored information. The server system also stores conditions relating to the generation of provided information, to be provided to the user in order to improve metrics obtained from the stored information, or metrics included in the stored information. The provided information is generated on the basis of the stored information and the conditions, and is transmitted to the user's terminal. The server system performs an analysis of transmission information acquired after the provided information has been provided, for a plurality of users that have received the provided information, and updates the conditions on the basis of the analysis results.
The rest are: WIPO Patent Application WO/2015/107710, WIPO Patent Application WO/2015/107743, WIPO Patent Application WO/2015/107744, WIPO Patent Application WO/2015/107745
As always, it doesn't mean that these will carry-over to the final product (if it ever it actually materializes) but at least we get a better idea of what Nintendo is talking-about/working on.
