| Cool! So.. as much as I love the Yayagram, I think people
| underestimate the elderly and willingness to learn something that
| "makes sense" and technology that does not work against them.
|
| To give an example, my 103 year old grandmother didn't know a
| thing about computers until we gave her an iPad about 6 years
| ago. Now she's available on FaceTime and e-mails. For some reason
| she doesn't find messaging interesting. She has a variety of
| hobbies (like knitting, reading and TV) but she checks the news
| both in paper format and on the iPad.
|
| I am actually so thankful that iOS is relatively easy to
| understand and that Apple spent those millions on UX, because it
| could easily have gone the other way with technology working
| against her.

| Super cute and well executed project.
|
| But after imagining how this would work in practice, my loved

| some indefinite time later to recorded messages they might not
| even remember the contents of (I wouldn't), it seems comically
| sad. It makes me think of how unsatisfying it is to attempt any
| real convo over SMS.
|
| Then again, I'm sure it's a supplement to the weekly or monthly
| video calls they're already having where yaya gets to see and
| hear their grandkids. But I can't shake the pathetic vision of
| yaya recording a 10min voice message and then, three days later,
| getting "school is good thx yaya!!".

|
| Also, I know it's not meant literally, but its genderisation as
| 'granny' is a really problematic cliche that I wish tech folk
| would stop repeating.

| Look, let me put this another way, since I'm being downvoted.
|
| I think my 70 year old mum, who is a grandma, would find it
| patronising and sexist to have a device pitched to her as an
| easier to use version of the iPad she is a bloody master of in
| every way. She's far more adapt than my dad, bless him, but
| even he can use WhatsApp and the like fine after being shown.
| andrewzah wrote:
| It's called that because they made it specifically for their

|
| Also, that grandmother is _96_. That is not even remotely
| close to someone in their ~70s. It is also dependent on the
| person: one of my grandmothers (around 70) doesn't like
| ipads, and can operate phones a little bit. My other grandma,
| similar age, loves her ipad.
|
| You're being downvoted because you're treating this like a
| generalized business pitch, when it's a specialized hardware
| project someone did for their own grandmother, and gave it a
| cute name based on their language. If I made something
| specifically for my grandmother, I might include "bunica" in
| the name. Seeing as that's what my whole family calls her,
| and its a way to say grandmother in Romanian, which is a
| gendered language.
|
| Also, I fail to see how the gender of the word for
| grandmother here is relevant for the discussion. Grammatical
| genders (also called noun classes) are not necessarily
| related to human sexes, but I digress.

| Actually, I wanted to say something very similar. And when
| you said it was for his very specific _96_ year old
| grandma, I went back and checked if I missed the obvious.
| But a quick 2nd scan (and a search on the string 96) didn't
| bring it up. I'm not saying you're wrong, indeed I'm pretty
| sure you're right, but it's very-very far from obvious.
|
| Also, the initial tweet itself talks about the issue in
| pretty generic terms: "a machine that helps our beloved
| elders to keep communicating with their grandchildren ."
|
| My parents are around 80, and granted my father was an
| engineer and my mother a _programmer_ they did have
| exposure to computers from their 40 's and 50's. (Actually,
| my mother started around the age of 30, but my father only
| when he was 50.) Sure, another 15-20 years make a lot of
| difference.
|
| However, plugging cables is more 1900's technology (reminds
| me of the manual switchboards). I doubt too many people
| alive today remember having to make a call like that as
| opposed to dialling. They did use radios that had push
| buttons and most of them for sure used ones with digital
| tuning. So while it looks very retro, a simple turning knob
| would have been a lot more sane. (Unless grandma used to be
| a switchboard operator :) and still has good hand
| coordination.)
|
| The other thing I don't get is the thermal printer. I mean
| it's nice as a (very short term) archival device but an LCD
| screen (or even and e-ink display) would make a lot more
| sense. Of course, then you have to add scrolling (that
| could be a tuning wheel-like thing or just up/down
| buttons). Or well, maybe they would like to hear their
| grandchildren :).
|
| But I digress: the point is that it was phrased pretty
| generally and I also think it's very patronizing. (My
| parents use skype, viber, email, fb chat as they did use
| SMS and their mobiles.) While sure, there is value in
| completely tailoring it to the needs of specific person.
| Just don't think it's in general a good approach.

|
| Maybe 7 years ago I set my parents (late 70s) up an old PC with

| needed a way to send photos to them. Before this the most
| technologically advanced thing they had used was a VCR - and

|
| Well the opposite happened, they really took to it. My dad even
| setup an online store trading LEGO. Yes of course there were
| issues (it took maybe 3 months of video calls to explain how to
| copy and paste), but they got there in the end.
|
| The other week my uncle (same age, they are twins) talked
| through setting up my father on Zoom and he joined in a video
| call with a social group they went to. My mother doesn't use
| the computer as she has arthritis (and I don't think my father
| let's her :D), but flicking through Google Photos on an iPad
| lets her keep up with the grandchildren.

|
| I've observed this as well. The hardest part are the basic
| concepts. Examples:
|
| - The idea of a "settings menu" itself is somewhat of an
| alien concept and mostly limited to devices with screens.
|
| - Not all UI elements have obvious meanings if you aren't
| already used to them.
|
| - The input device itself might be unfamiliar (mouse,
| keyboard, touchscreen) and the user's brain might be busy
| trying to understand how to interact with the device at
| all, let alone do useful things with it.
|
| - Some users never learned the "why" or even the "what" of
| existing devices, only the "how" -- they don't understand
| concepts like "applications", they just follow very
| specific steps that someone laid out for accomplishing
| specific tasks. This makes it very difficult to discover
| functionality or adapt to a different UI, because they
| don't know what anything actually is in the first place.

| Final = pin1-pin2 = X+noise + X-noise = 2X

| Brilliant.
