Adaptive Motion Gaming AI for Health Promotion
This paper presents a design of a non-player character (AI) for promoting
balancedness in use of body segments when engaging in full-body motion gaming.
In our experiment, we settle a battle between the proposed AI and a player by
using FightingICE, a fighting game platform for AI development. A middleware
called UKI is used to allow the player to control the game by using body motion
instead of the keyboard and mouse. During gameplay, the proposed AI analyze
health states of the player; it determines its next action by predicting how
each candidate action, recommended by a Monte-Carlo tree search algorithm, will
induce the player to move, and how the player's health tends to be affected.
Our result demonstrates successful improvement in balancedness in use of body
segments on 4 out of 5 subjects.Comment: A revised version of our paper for 2017 AAAI Spring Symposium Series

A Personalized Method for Calorie Consumption Assessment
This paper proposes an image-processing-based method for personalization of
calorie consumption assessment during exercising. An experiment is carried out
where several actions are required in an exercise called broadcast gymnastics,
especially popular in Japan and China. We use Kinect, which captures body
actions by separating the body into joints and segments that contain them, to
monitor body movements to test the velocity of each body joint and capture the
subject's image for calculating the mass of each body joint that differs for
each subject. By a kinetic energy formula, we obtain the kinetic energy of each
body joint, and calories consumed during exercise are calculated in this
process. We evaluate the performance of our method by benchmarking it to
Fitbit, a smart watch well-known for health monitoring during exercise. The
experimental results in this paper show that our method outperforms a
state-of-the-art calorie assessment method, which we base on and improve, in
terms of the error rate from Fitbit's ground-truth values.Comment: The AAAI 2018 Spring Symposium on Beyond Machine Intelligence:
