Can walk inside a vr environment with only using mobile's gyroscope?I noticed only rotation is possible.

Hi all,
I’ve been creating a vr environment with machinery and then exporting them to a mobile application(to be used in the HMD) but i noticed only rotation from a “player start” position is happening.When i walk around,the character pawn does not move…Can’t the mobile ■■■■■ the accelormeter and make the character pawn walk in(VR) whatever way im walking with “HMD” on real life. I only have a thumb joystick as an external control,IF i have to set up blue print to achieve what im trying to get.how should i approach blueprint…I’m very doubtful whether the thumb joystick can be programmed(in blueprint) to make me feel move in VR space.

Thanks in advance,
