Accessing / Switching / Editing profiles directly in Unity

[MingJ]

Hi,

I’m currently working on a game project on Unity 5.0 that is meant to be played by different players.
My game will be played with a touchscreen connected to a PC and there won’t be any device other than the eye-tracker (no keyboard, no mouse, no gamepad, etc.)
Before the game start, my app asks the player to enter an username with the visual keyboard I made and then it launches the calibration tool directly from Unity.

The problem is I don’t know if the player will have glasses or not, and the only way to set this option (as far as I know) is by creating a new profile. But I don’t want that, because he/she would have to enter a profile name and there’s no keyboard to do it.

The only options I thought of are :
1. To ask him/her in the game if he/she has glasses or not and then set it in my code to Guest profile or whatever.
2. To create 2 profiles (one set to glasses and the other not), then ask him/her and switch between these 2 profiles depending on each case.

I didn’t find any way to do this yet so I’m asking here for some help from anyone.

Thanks in advance

Can’t edit the post so I’m just leaving it here : first tag is wrong, it’s C# not C++

Hi MingJ,
let me tell you about one of our best kept secrets: 😉

The reason why we ask for glasses/contacts when creating a user profile isn’t so that we can track better. No, it’s a way to let people who e.g. sometimes wear glasses and sometimes wear contacts to set up different profiles and switch between them — and perhaps even more important: it’s a subtle hint to the users that you need different calibrations for different kinds of eyewear.

So if your game is to be used in a kiosk-like environment (if I understood that correctly?) then a plain guest calibration should work just fine. No need to worry about glasses.

Hi,

Thank you for your answer ! Now I guess I don’t have to worry about that part of my game anymore.

Just to be sure, since you didn’t mention it I guess what I was looking for cannot be done (yet?)

Hello MingJ,

You cannot (yet) create or switch user profiles from the Unity SDK, but you can launch a re-calibration and also test eye tracking by using the LaunchRecalibration and LaunchCalibrationTesting methods available on the EyeXHost class.

There is a demo project in the SDK zip package called Calibration that will show you how to do this.

Okay, good to know that. I already knew about the calibration and used it in my game. If I’m not mistaking you can also create a profile from Unity, I guess you meant ‘edit or switch’ ^^

Thank you for your support and quick answers. I hope your product will get famous, it’s a really great tool.

Hello!

Out of curiosity, what game is it you are working on? 🙂
