Why dismount requires getting off the sensor

@gadgetrider You wouldn’t do a split, because one foot would be on the tail and the other foot would be in the air. You’d only put it down once the board stopped.

I find the 2 sensors dismount brilliant and convenient.

About the only disadvantage is the myth that people were nose diving due to sensor malfunction, but this hasn't been proven.

I think it's why FM made a wider sensor area on the + and I find it annoying and it seems to cause dismount failures more often the original IMO.

For us who've been riding for a while, we can manage and adapt, but for newbs who had issues with dismount on the original, will find the + a bit harder until they get the hang of it. The dismount feature needed no upgrading IMO.

The other safer way is an easy mod. Hook a cable with a switch and turn it on manually once you level and hang the switch like a key chain, turn it off before dismount. Have a connection that comes off and cut the power in case of a crash. No runaway board and no fear of sensor malfunction.

Thought of doing it, but I trust the sensors to a point where I don't see the need.

Can't relate. I own a V1 and dismount is a breeze. you just heel-toe your way to the front of the board and slide your foot off. I've never ridden a plus but I imagine that the wider sensor makes that difficult, but not impossible. You seem frustrated, try to relax. Onewheel is a thing of beauty and has brought me nothing but joy since getting the hang of it.

@rk_d That's a train-wreck waiting to happen and ethically I wouldn't attempt such an experiment knowing it may hurt the rider.

Just like any serious mode of transportation, it would be unconscionable to let an untrained rider get on a device without proper warnings and training. I always tell me newbie riders how to dismount by jumping off with both my feet at the same time and if they want to get fancy, they can learn the footpad sensor off method. Instructions for Use are there for a reason. I wouldn't get into a car if I have never driven (maybe that's an extreme example) but the point is the same.

Can a better dismount method be devised? Possibly but even after reading your alternate solutions, I can see both pros/cons to all of them and none of them to be significantly better than what is implemented at this moment. I have no knowledge as to whether an accelerometer is incorporated into the hardware though I do know an inclinometer is.

I would suggest that you send some of your ideas directly to FM so that they can assess whether to implement some of these options in future firmware revisions. We - on this board - cannot do much with the brightest ideas since we do not have the ability to make any product changes naturally.

Don't get discouraged if you feel the rest of us are complacent about improving on the product but as more mature owners, we are finding that the current implementation is pretty good so far. I am sure we would welcome improvements as they are found. To suggest that the brightest minds in Silicon Valley have not done enough to make the product safer would imply that you know better than those who live with this product every working hour. That's a tough call in my mind but you are free to express your opinion about it.

@rk_d said in Why dismount requires getting off the sensor:

This morning I have been contemplating demonstrating this problem on You Tube by putting together a legal waver and asking passers by to take a ride on the board without being told anything at all about how to dismount knowing that it's dangerous to get on if you don't know how to get off.

You are a psycho!!!
Would you do that to your mother or sister?
What if during driver’s ed, someone put you in a car without telling you where the brakes were?

@rk_d All terrible ideas. Shut off system is fine as is. Also, people aren’t just hopping on these boards without instruction....unless your a bad friend. I have had countless people try my board and I instruct / show them how to operate it. When I received my board, I also read the instructions (mind blowing concept right!).

As for your ideas:

1. nope. If I’m at a stand still and want to turn the board around 180 degrees so I could ride switch, I don’t want my board shutting down.

2. likewise, if I’m at a red light or crosswalk and I want to stay on my board so I am ready to go when the light changes, one naturally wiggles back and forth a bit staying balanced. Absolutely don’t want my board to shut off in that situation.

3)....this doesn’t even sound like a coherent solution.

This forum is getting funnier every day.

@rk_d No worries! Only want the people with common sense reading that, so no crazy ideas get passed through and ruin the riding experience. Stay vigilant!

I think of the current sensors as safety switches. Like a lot of machines / equipment you need to push a button or hold a trigger before it will turn on. The sensors are an easy way to know a rider is there and the board should balance when brought to level.

The dismount logic makes sense to me for two reasons. 1. If you have to jump off above 1 mph because a car is coming at you, you’re losing it down a hill, etc... you just take your weight off the sensors, board turns off. Regardless of the acceleration or incline or anything. 2. The logic also dictates that if you meet two simultaneous criterion (only one sensor engaged and <1mph speed), you must want to get off the board.

The sensors are an on & off switch and kill switch all in one. Not saying it couldn’t be improved but I feel they covered the bases pretty well.

[Gadgetrider]

@skyman88 And all this without resorting to a remote! That's the elegant part. But perhaps for those that are really challenged to gracefully dismount, a small wireless remote can be purchased to act as a kill switch. I am not sure I would necessarily buy one but hey - everyone is different.

@rk_d said in Why dismount requires getting off the sensor:

(1) from a stand-still roll the board more than a preset number of degrees in either direction. Default to 25' and allow the user to change in the app, for example, from 10' to 75'

(2) from a stand-still, wiggle the board (accelerate in both directions alternately and very quickly) back and forth for a number of times that can be set in the app. Make the default 100 and allow it to be dialed down to as few as two times.

(3) make a setting in the app to disable the board powering down based on the foot pad sensors. Note that this would require extra programming to prevent the board from running off without anyone on board. This is not a hard programming problem if you have an accelerometer and you can measure the effect of torque on the rotation of the platform (IE: measuring the angular momentum of the platform).

What a load of gibberish.

[Gadgetrider]

I thought about #3 some more and I just don't see how that is going to work either. Assuming it has an accelerometer, by the time the board senses the OW has accelerated faster than what is possible with a rider onboard AND determined that the torque load is very light, the OW is already a launched projectile. Sure the motor would hit the brakes suddenly to compensate but it is already moving. Also if a rider goes down a small depression on the ground, the OW will accelerate due to gravity and the torque will be low - thus it would think it should stop and launch the rider forward. Like I mentioned before, there are smarter people than me that can comment as to the feasibility of these ideas but I sure don't want to be the human guinea pig.
