Show HN: Drivr - VR with real vehicles [video]
This project combines VR with a real vehicle that you are
controlling (or is controlling itself, in some scenarios). One
advantage this has over traditional VR motion experiences is that
your senses all agree with each other, thus greatly reducing the
likelihood of motion sickness. The go-kart seen in this video is
drive-by-wire and steer-by-wire, so the system will not let the
player exit the defined safe area. If a player goes off course, the
vehicle will take control, and return them to the start. The
autonomous capabilities also allow for games where the player can
focus on other objectives other than driving, such as target
shooting. No infrastructure is required other than the vehicle and
an open place to drive (which honestly has been the most
challenging part lately). If you're interested in this project,
I'd love to connect!

| Great project, keep it up.

|
| this is very creative the pros from this vs a 6DOF simulator is :
|
| - REAL terrain feedback
|
| - REAL winds blowing in your face
|
| - REAL feeling of being outside.
|
| - Imagine a real life mirio cart
|
| All we need is a AR version of this and we can gamify traffic irl
| (for example yielding earns you bonus points, shoulder checking
| increases your rep points)

| For anyone who doesn't have a gokart and a runway and love cars I
| just got into the real sim racing with force feedback wheel +
| 8spd + clutch + ebrake and it is *so* much more realistic than I
| ever expected. I never understood how racing sims were so popular
| because I had only ever played them with a controller and I
| didn't know force feedback was anywhere near what it's actually
| like on a good wheel. My wheel can violently rip out of my hands
| in a crash and at only 8nm power which is nowhere near the top
| end wheels. About a $1k investment.
|
| It is a completely different ballgame using a direct drive FFB
| setup like a Fanatec, etc. Driving a 1000whp Supra on Shuto
| Highway in Tokyo is so cool.

| That video is rad! I had a wheel/pedals/6spd setup in college,

| feels like a big lift in a real world setting. If there was a

| the potential to notice it and ride around. With a headset on,
| they're really trusting the operator to do good maintenance on
| the playfield.
|
| A go kart has 4 points of contact, a low center of gravity, and a
| limited top speed. Those are all good factors to limit
| catastrophic crashes. But also, imagining a rink run by high
| school kids where nobody can actually see where they're going
| gives me some pause, even if this looks super cool and I want to
| do it.

| In regards to multiple vehicles, you're absolutely right. At

| Have you tried the analogue of "redirected walking"? I.e. the
| cart goes a partial circle but the user sees a full circle in VR?
| greghgradwell wrote:
| Haha, yes, the graphics are definitely not going to win any

|
| I've been impressed with techniques like redirected walking.
| People are so clever! For this application, I think it would

| can scale the players perceived speed with a simple multiplier,
| e.g., have them move 2 meters in the game for every 1 meter
| they move in real life.
