What would you think of additionally using gyro and acceleration sensors to create new gestures?

For example I could think of tap and hold my thumb on display and wiggle the phone to quickly shut down all network devices. Another feature could be to zoom pictures by slightly tilting forth and back the phone (or tablet) while one (or two fingers) on display.

Simply put, this way a whole lot of new gestures would get possible.

With the phone not fitting well in the hand i can see this resulting in many dropped phones.

I didn't mean to shake the cpu out of the box. :) If one can handle the phone with one thumb s/he shouldn't be too likely to drop it while moving it with the thumb on the screen.

Well would be a nice to have feature along with the (hopefully before 2.0 upgraded ambience customization)

The end of usability, we will all end up being scared while listening to music, frozen in our seat as any movement could trigger the next song, change volume or shuffle the playlist indefinitely...

A gesture is always result of a distinct combination of different sensor signals. Your suggestion is an analogy of a touch screen that went off while having your phone in your trousers.

Shake to shuffle Shake to refresh

and bump to the table to shutdown?

cemoi71 ( 2015-07-22 23:35:52 +0300 )edit

what should be shuffled in the phone?! is your phone a game?

cemoi71 ( 2015-07-23 12:47:48 +0300 )edit

@vattuvarg right ... seems to be a function for a specific app (understand for a story app), not for a whole system handling. can't still represent me what could be shuffled in a system.. sorry :-( (shuffle is for me blurred in a mess or in an other typ of position)

cemoi71 ( 2015-07-23 19:20:19 +0300 )edit

You can shuffle colours with a home led lighting system already now using your phone (Philips hue). Or think of shuffling for the next song - not while jogging, though.

Pickup to answer an incoming call.

Flip (turn over display down) to reject an incoming call.

The latter is already implemented.

wanderer ( 2015-05-10 10:51:36 +0300 )edit

And when I want to decline a call I just pick it up and pul... no wait... Did I just answer it?

Okw ( 2015-05-10 12:42:23 +0300 )edit

This might not be feasible as a general option as @Okw indicated, unless you would never want to ignore a call. But I remember that there was an option accept every incoming call on Nokia phones.

lakutalo ( 2015-05-10 14:47:46 +0300 )edit

This can still be done. Simply holding the phone next to the ear can easily be predicted by the gyro along with the ambient light sensor.

mlwane ( 2015-05-13 04:02:08 +0300 )edit

@filipb92 please not this in this way. i want to pick up just for seing who call me! to answer, better is for me a clearer action. if you want the phone could recognize my ear. but for this no pickup gesture... forbidden!!!!
please put more thinking on it, or forget it.

I posted an idea a while back called downsideUp. Basically it is about using the fourth orientation that isn't used at all now.

edit flag offensive delete publish link more



That's an interesting idea! It could also be extended by the number of rotations which are in fact distinguishable from accidental input.

lakutalo ( 2015-05-12 12:27:17 +0300 )edit

@vattuvarg please described what is exactly a downsideup move, so that is no possibility for the developper to misunderstand this.
i have an idea, but don't know if it this:
First dump fast down
then dump up
Like a bottle to shuttle in 2 tacts
is that right?

should be then a view, configurable from user?

cemoi71 ( 2015-07-23 12:38:41 +0300 )edit

Imagine that you are holding your telephone and that you have a friend on the opposite side of a table. He or she asks for your telephone number. You reply by opening the people app, quicikly highlighting your own phone number and then turning the telephone so that the screen faces your friend with the microphone down. The downside up view coulld show your phone number in a larger font on an avatar background.

Portrait view as well as landscape left and right are used by Sailfish OS, but not the fourth view. No, it's not just the portrait view flipped upside down, it's a completely different view. You could call it a "social" view.

I call it downside up.

vattuvarg ( 2015-07-23 18:35:21 +0300 )edit

@vattuvarg you mean in this case the microphone of the upper-side right?
so let me try to break your concept, then will see if it's a good one:

it depends then if user really like to do this gesture.
For this kind of action, i like better to turn my phone on the vertical axis rather than the horizontal one (better for the wrist, and partner in front of you don't need to stand up because of disturbing light reflections).
for some boat or flight boarding, you need to place the barcode looking to top. for some other should be to the ground..
I think the fourth view is not bad. that's great. but i think it need a clear gesture to activate, and the same to deactivate. For example shuttle 3 time -> is on, shuttle 3 time, -> is off (shuttle gesture is maybe stupid, is just an example).

cemoi71 ( 2015-07-23 19:06:14 +0300 )edit

I am so totally dead tired today...

What I really mean isn't the microphone but the earpiece on the phone. When turning the phone the display should be facing the friend with the earpiece down. Sorry.

A feature-Idea which would be useful in combination with already requested feature to switch the UI between right- and left-hand mode:

Tilt the phone slightly (about 30°) to the left or the right to switch the user interface between left-hand and right-hand mode. To prevent accidentally triggering this action, it should be triggered after holding the phone tilted for 1-2 seconds.

For better usability the UI elements should move like weights following gravity and floats following buoyancy, when the action is triggered, to understand what's happening.

edit flag offensive delete publish link more


@wanderer What is the need of this gesture for you? what should it fulfil? do you want at any time in a day change the handling right or left? Or is it just for one time.
for the last case i propose an easier way, is to place a switch button right or left in system configuration.

please add a description for what exactly it is needed. with the current stand, i'll expected a fully odd behaviour in the phone, when i put it in my trousers pocket. Would give the impression of a random right/left handling

cemoi71 ( 2015-07-23 12:33:27 +0300 )edit

The idea is to change the handling at any time, depending in which hand you are holding your phone. I often change the hand i am holding my phone with.

When I proposed this idea I was thinking especially about the sailfish-browser with its functional icons in the navigation bar. There are different icons on the left and right side, which are a bit uncomfortable to reach if you hold our phone in the "wrong" hand. Instead of changing the hand or bending the thumb, instantly changing the position of the icons by tilting would be a nice feature.

But I have to admit that the browser is the only example that comes to my mind, where this feature would make sense. In most parts of the system the usability is smooth in either hands, so this is not necessary.

wanderer ( 2015-07-23 13:07:05 +0300 )edit

@wanderer interesting use... use is for you just the browser, and that is simply enough to clear it, if you use it the most of the time of your day. I think your definition for preventing of use it accidentally a little bit too weak. in my pocket the dewvice could be tilted and holded more than 2 seconds.
right, maybe display should be on and device should be not spared, so that could be happened (should be given). But both could be happened in a pocket, if user never spare his phone, and display go on by phone call or alarm.
something physical as interaction should be added. don't know. maybe having the finger on the bottom of the display.
means if tilted slightly by holding the phone with thumb on the bottom of display, then it happens. maybe you could have something better. :-)

cemoi71 ( 2015-07-23 13:43:23 +0300 )edit

@cemoi71: I don't see a problem if this feature would be triggered accidentally. If it would be used in the browser, it would just mean that the four icons in the toolbar would move from left to right and vice versa. It could be simply reverted by tilting in the appropriate direction.

wanderer ( 2015-07-23 13:59:23 +0300 )edit

@wanderer for a web browser seems not to be really disturbing. otherwise for nitpicker (like me). for other apps i don't know...

Shake phone to dismiss alarm as requested here:

edit flag offensive delete publish link more


@lakutalo shake in which direction and axis? and how strong. currently could be interpreted as a flip action.

why not use the expected reaction by turning the phone too?

cemoi71 ( 2015-07-23 12:41:54 +0300 )edit

Flipping it over would only put alarm into sleep mode for another 10min. The idea in the request quoted was to dismiss the alarm. A shake gesture could be 2 to 3 sensed alternated accelerations within 1s which would be quite well distinguishable from a flip-over gesture.

lakutalo ( 2015-07-23 13:27:42 +0300 )edit

understand better now... my reaction was more that your response goes more precise in description... ;-)

sorry for all the bad jokes but, those typ of feature will make a lots of unexpected events if i put the device on my pocket. If i dream for a calm day, then hoho. But if i need some entertainment. why not. That's not that i am against it. but it is very complex to develop this kind of gesture, so that for each gesture should not be interpreted to an other one. At the current state of sfos, all jolla dev are busy to have the first basis of it. Is too much effort, for having a near 100% efficient. For reality game, could be really fun!

ps: if someone see me acting with my phone with all kind of GAGs (Gyro & Acceleration Gestures) , he will think that i went back to the childhood (babytime better said).

I understand well enough that this sort of gesture is not one straight forward and easy to conceive of. That's why I'm bringing it up for discussion. Did you know we already have got us at least one gyro accel gesture? Look-a-here, by the critic himself :). It's all about the context we want to sense movements in. The lack of distinct keys first brought up the necessity of additional sensors.

Regarding other more important issues, it's never too early to think of enhancements, they just don't need to be prioritised. Later on one can grab into a pool of ideas. That's what basic research is all about. Radon himself did not guess what use his transform could be of a century ago, now it is the heart of every CT scan!

lakutalo ( 2015-07-23 10:02:40 +0300 )edit

@lakutalo yes i know this gesture, i use it fast every day.

as i told i have nothing against other one. But it should be well thought and be really robust. At the end it should be always someone who disturb a little bit all the thinkings, so that grow a little more from naive and not completely well though to a better concrete one.
And give by a lots of reflection and contradiction, to appreciate really if it is needed or not. and used as as it is described.
Currently Some of ideas, as user i can't represent me that is usable. It will nerve me. But maybe it has potential. and with a lots of contradiction, we could improve it, or simply forget it.
do you understand why i have reacted as i did?

Gyro cover action

Imagine pressing the cover of the media player and then tilting the phone left or right to raise or lower playback volume.

Would that be possible?

Tilt Left- navigate backwards (think shake once left) Tilt Right - navigate forward

This could be used in browser, when navigating through online image libraries, or in Gallery when navigating through images, or when skipping a song or going back.
