Wearable: suggest products: (1) media remote ring, (2) touch to XXX ring



 I just sent the following to Amerteer, from whom I bought a "wireless(BT) Presentation clicker ring"


Amerteer's website  not spelled the same way: http://amteer.com/Empty-contact_us.html


Because I like to see anybody do this .  Amerteer just came to mind because I've already bought 1 of their products.

I bought your  presentation clicker ring.   it shows promise, although the key bindings you have used are useless for my purpose.

May I suggest that you consider creating a "media remote ring"?  Like the Satechi Media Remote Ring?

Buttons  for each of these following standard PC key codes

Media_Play_Pause
Media_Next
Media_Prev
Volume_Up
Volume_Down

Noting that  this media remote has 5 buttons just like your presentation clicker, arranged in the same shape. The only differences that the key codes  sent to the PC are different -  and possibly the  symbols you print on the keys might be different.

I suggest the media remote ring because  it has a  big market comparable to your presentation clicker ring.  Which is more common?  PowerPoint presentations, or playing video? (Or both?)

I have other ideas for such ring devices.

E.g. I would like a push to XXX  button - a button that I can touch lightly.  When I touch, it emits a keycode like Media_Play_Pause DOWN.  When the touch is removed, it emits the keycode Media_Play_Pause DOWN

I.e. separate control for touch/down and release/up.

I am able to do this with the Satechi media remote ring,  and other media remotes.   however, the membrane buttons they are using require too much force me to keep press down, so using them for press to talk or  press to play  is uncomfortable.   therefore I'd like to suggest that you  use either a lighter touch button, or possibly a capacitive sensor  that can just tell when the fingers touching.

 I would prefer  key up/down push to touch  to auto repeat.   I don't know how widespread my need is, although I think it's more common now that touch phones are very common.

BTW:  my application: I use a dictation device  with speech recognition software. I would like to  "press to talk"  when I am dictating/talking to my computer. Faster than having to click a mouse button or the like, since I'm operating totally hands-free.

 I am currently using the Satechi media remote key,  but like I said the button requires too much force and is uncomfortable for push to talk.

---

Like I said, I have other  ideas for rings/finger worn devices.   as I am sure you  know,  there are many fancy proposals like gesture control and NFC and  Biometrics so on.   Those are great -  but your  presentation clicker and/or a media remote ring  are much simpler, and can be done with what you currently have. Just a slight reprogramming of your existing device.

 In fact, I don't even need all 5  buttons on your current presentation clicker ring device.   I would actually prefer to have only a single button. smaller, etc.

Trackball scroll ring causes "computeritis" ?! :-(

I have long used a trackball rather than a mouse.  It greatly helped my "computeritis" - sore hand/wrist/arm.

One of the first trackballs I used, and my longtime favorite, was the Kensington TurboBall.  4 buttons and a scroll wheel - which IIRC could also be clicked as a 5th button. But it was discontinued by Kensington, probably because it was a mechanical trackball, and had reliability problems.  After many years all six (6!) of these that I had purchased failed. I have not had good luck with the used TurboBalls that can still be purchased on Amazon.

I am currently using the  Kensington Expert Mouse. 4 buttons, and a scroll ring, non-clickable. Actually 2, one on either side of my keyboard. 2 more at work, 2 more at the coast, 2 more at my mother's house, and 1 in my suitcase for trips.

I guess that you can say I have liked the Expert Mouse well enough to buy 9 of them.  Serious $$$s.

But: I dislike its incline - I am currently shopping for a mouse tray to give it a negative incline.  Or at least foam blocks. But at least that is hackable, although even a non-tilting mouse tray costs more $$$s.  I have even tried using the trackball upside down, to get the negative incline I want. Works okay, but the USN cable gets in the way.

Worse: I have come to realize that the ExpertMouse scroll ring is bad for my "computeritis".  Scrolling a ring is a much more complicated movement than scrolling a wheel.  It uses many more small muscles.  And my hand/wrist gets sore.

I wish I had my old scroll wheel.

I have been worked on AutoHotKey scripts to scroll using the actual trackball.  Works somewhat.  Most existing scripts require holding a key to scroll with trackball, which hurts; but it's easy enough to make a key press and release toggle the "scroll with trackball" mode.   Worse: in AutoHotKey scrolling with trackball seems to require a timer triggered polling function, wasting power.  Plus other issues as I mention in an AHK forums post: problems with displays that have different display scaling, cursor flickering, etc.

I am considering buying a trackball that has a real scroll wheel.

Or  possibly one of the ITAC trackballs, that has a mode button converting it into scroll mode: the ITAC Evolution 149$ 6 buttons  or ITAC Professional 189$ 4 buttons. The former's 6 buttons can all be configured. No driver SW required. OS independent.  But probably only scroll up/down - no scroll left/right, without more OS dependent AHK scripts.

BTW, more and more I prefer OS independent driverless devices.  Programmable once, then works everywhere else.  E.g. I might be able to program mirror images of the ITAC Evolution, so that my left and right thumbs always hit the same button.

I am seriously considering buying the ITAC Evolution,. But since I nearly always buy more than 1, this quickly becomes serious money.  Still, hand pain preventing me from working can cause serious loss of income.

OneNote LOG special page naming conventions


e.g. ** Tuesday, March 19, 2019

A "** Day LOG page".

Special page indicating start of a day.

NOT necessarily containing the actual log entry

Frequently empty, with OneNote pages for that day following.

Sometimes I add comments, etc., about the day.

The creation date for for a "**DayLogPage" is typically set to 12:00AM midnight on that day,
in the timezone I was working in at the time.


Mostly NOT using OneNote sub-page indentation

I would like to use OneNotes parent / sub-page relationships - but OneNote only supports 3 levels (top,sub,subsub), which is nowhere near enough.

E.g. I might like to have collapsible Week/Day/Topic/sub-Topic) hierarchy


. Spacer Pages

I find it convenient to have spacer pages in the list of pages within a OneNote section.

Since empty pages get "Untitled page" implicitly supplied, instead a use pages whose title is as close to invisible as possible, just a "." (period).



---+ section special pages

I use these to divide the pages for a day into sections.
---+, ---++

Default sections are for sorting - taking Raw LOG pages, and dividing them into work and non-work related pages, so that I can separate work and non-work

---+ Work - Restricted

Stuff that is work restricted, sensitive, or proprietary - stuff that should be moved to a company notebook, stuff that I am not

Sometimes I may leave a link to such work restricted stuff around in my personal notebook LOG.

Sometimes even the title of the page is restricted.

---+ Work - Related - Public or Personal

Stuff that is work related, but which is not company proprietary, or secret.  Stuff that may be left in my personal notebook - although I may move a link to my work notebook

E.g. HR stuff. 

E.g. public technical papers, that I think may be relevant to work projects.

---+ Personal or Public - not Work Related

Stuff that is not work related.  Stuff that need not be moved or linked to a company notebook.

Not distinguishing public, personal, private.  Assume personal or private.

---+ Not Yet Classified

Typically I insert a block of special pages


** Tuesday, March 19, 2019
---+ Work - Restricted
---+ Work - Related - Public or Personal
---+ Personal or Public - not Work Related
---+ Not Yet Classified

collect OneNote pages under the ---+ Not Yet Classified
special page "section",
and then during review move them to the appropriate classification,
and thence to the appropriate company proprietary or personal notebook,

DHMXDC Surface charger: fails new PC, works old PC


I wanted to post this review on amazon.ca, but was not eligible[*], so I am posting here:

DHMXDC Magnetic US Plug Power Supply AC Adapter Cord for Microsoft Surface Pro 3/PRO 4 Intel Tablet (Pro 3 Adapter Without Usb)(Taboe Charger)Sold by: DHMXDCCDN$ 20.00
 
I forgot to bring an airplane-ready[**] laptop charger on a recent trip, so I purchased this from amazon.ca on the plane while travelling to Canada.

This charger did NOT work with the Microsoft Surface 2-in-1 tablet PC I was using on the trip. When plugged in (a) the charger connector lights up, as if working, but (b) PC system icon reports "plugged in, not charging".    This seems to be as reported by about half of the reviews.

I initiated a return request with amazon.ca the same day. The vendor responded, but had not authorized the return before I had to leave Canada.

On my return home, I found the the DHMXDC charger worked with an older Surface.  I will therefore keep it - too much hassle to get the vendor to complete the return authorization - but I will be reluctant to work with this vendor again. 

---

Note *: Since I live in the USA I normally use amazon.com, where I post reviews, rather than the Canadian site, amazon.ca which will not allow me to post a review unless I have purchased 50$ in the last 12 months.  Amazon.com will not allow me to post a review for a product I purchased on amazon.ca

Note **: by "airplane ready charger" I mean a charger that will work with the power outlets on many airlines.  The surface dock that I was travelling with drew too much current, and caused the air line power outlet to shut off.

IT forced password changes => weaker password

Every time my company's IT forces me to change my password, my password becomes weaker.

At least, the password(s) that I actually have to enter by hand, manually.  

Frankly, I don't care about weakening the passwords for my company accounts.  After all, it's their IT department that is enforcing this obsolete policy.

But it is annoying that company IT also forces me to change my personal password on my personal machines that I use to log in to company email and VPN.   Those personal passwords start out really string, but get weaker every time IT forces me to change them.  So it's my personal security that is being messed up by company IT.

Treadmill (desk) needs speed ramps and intervals

I continue to love my LifeSpan TR1200-DT3 treadmill, since 2014.

At first I could only walk slowly, 1-1.4mph, while working.

Then, a year or so ago, I started being able to hit 2-2.5mph for some tasks, like email triage.

Recently I have started being able to run >= 4mph, typically while listening to "XXX Update Meetings", where I don't participate, and often don't need to take notes.

But... sometimes I need to take a note, and may need to slow down.  Not suddenly stop, but ramp down safely. 

(Stopping suddenly can be dangerous - I have twisted my knee several times when the emergency stop engaged.)

PROBLEM: the LifeSpan console changes speeds in clicks of 0.1mph.  Having to lean over and click 20 times to ramp down from 4.0 -> 3.9 -> 3.8 -> ... -> 2.1 -> 2.0 mph is inconvenient, and somewhat dangerous.

WISH: 2 or 3 speed buttons, with designated speeds.  And a smooth transition between them, not instantaneous.

EXTRA WISH: I sometimes do intervals on my treadmill desk, while listening to such meetings. 20 clicks to change speed is a pain.  After the 2 or 3 speed buttons, programmable intervals, would be nice.

DIY: yeah, I should do this in my copious spare time. There's a small community of folks who have made their own treadmill controllers using Arduino or Raspberry Pi or the like.

--

BTW, one big reason why I did not start running fast earlier was not my fitness level or even my sense of balance, but that I have had trouble adjusting the treadmill tension: if it runs smoothly at 0.4 mph it slips at 5mph, or it binds at 1mph when smooth at 5mph.

Google Blogger/Blogspot "Blog This!" plugin dead?

As of June 2018 the "Blog This!" plugin seems to have disappeared. Sob! My second most frequently used plugin. This may be my final straw for using Google Blogger / Blogspot. Google Blogger / Blogspot has been dying slowly for years.
