Silent Invasion - AR Fitness Game

About this game

Silent Invasion is an AR weight training game for Microsoft Hololens2.
You will search for invisible invaders in your room, and destroy them using floating sphere nodes.

The app is available on itch.io and Mcrosoft Store;
Purpose of this project

The reason I started this project is to present the possibility of various options for fitness games.

Currently, most fitness games are focusing on aerobic exercises, rather than weight training.
Also, these existing fitness games tend to be more like apps managing users' daily routines, rather than content to let them consider the workout itself enjoyable.

What I aim to realize is a weight-training-focused game, that the exercise part is fully integrated into the game part as entertainment.
I would like to support users who have difficulty with keeping daily workouts (especially weight training) by making exercise itself fun.
Providing more variation of the type of fitness games would help these users to find his/her best option to continue the daily workout.

"Silent Invasion" proposes one of the alternative options for fitness games.

Game System
What you can do is to send ultrasonic signals by an exercise you selected.

For instance, if you select squat in the game;
1. Squat down to charge energy to send a signal
2. Look at the target object to send a signal
3. Stand up to send a signal to the focused object

By sending a signal, you can do either of two types of actions; Find an enemy or order a sphere node to attack an enemy.
These actions are switched depending on the type of object that the signal hits.
Key Features

Visual interaction with the environment
Two types of in-game objects, the enemies and the sphere nodes, affect the visual style of the physical walls and floors.
When they are close to the physical objects, patterns appear on the walls around the objects.
This feature helps users to understand the relative position of the virtual objects in the real space.
Snapping and lock-on by the eye-tracking
The direction to send signals is defined by the direction the player looks at.
But the cursor of the look direction snaps on the objects that the player can send signals; for instance, the hidden enemies and sphere nodes.

Also, the lock-on guide is displayed on the object to send a signal, which is the object looked at last time.

These guide and navigation features are implemented to help users to aim and shoot specific objects as they want, while their posture is always moving during the workout.

Getting look direction is achieved by the eye-tracking feature of the Hololens2.

Future Development Plan

- Enable this app to connect with muscle sensors, smart devices to detect movement of any body part
This feature enables users to choose more variations of the exercise, even if it requires a barbell or any type of machine.
