Usability and Accessibility Enhancements

Tablets have tools for Communication, Browsing and Many Utilities. It needs to be usable by very old people and very young ones as well.  They need to be affordable and Robust too. Ability to survive falls, Grime, Water and Heat. It should be usable by people having Health issues too.

Usability and Accessibility Enhancements

Alert sounds likes chimes and rings are not enough, The Tablet must be able to yell and scream when it is far from the owner. The user needs to wear  a Bluetooth pendent with microphone .

When charge is low, it has to create a tantrum till it is fed...up. Some pricey models can have tiny wheels to move to the closest charging bunk. Some Vacuum Cleaners are able to move and recharge themselves.

When a SMS lands, it is able to read out loud and take a reply by voice and send it at once. Similarly the email could work on the tablets, all hands-free. The speakers and quality audio are on the tablet/pad and the pendent is just an additional microphone with bluetooth and vibrator with a titillate option.

Incoming  calls can move in tandem with an answering device and make loud Audio Visual Effects to get the attention of the Owner. The caller cannot wait, so the answering machine takes the call, says "please wait" and then rings the Alert Alarm Bells and even vibrates the Pendent. The Senior now can talk to the pendent and will get the caller's voice loud on the Phone. The Phone Audio has to be very good and loud.

If the room has a connected HD Monitor, even that can be used for the communication purpose. The user just needs to click the pendent to answer a call or video chat with family friends. In Business too, Large monitors and Loud Speakers can improve communication.

Smart PowerPacks or PowerBanks+ can be the Charging Stations. The Power Packs with docks can have the wheels and intelligence to recharge the device on alert, they will also recharge themselves from the mains power, whenever required.

Expensive Phone or PowerPack Models can have Drone Mode. I say this emphatically because the Dilbert Dupey develops wings after the mutation, This indicates that quad-copters, drones were predicted. It could be that, One fine Day the Tablet+ may Fly!

Online Security in Embedded Systems

These days many gadgets with embedded systems are being used. Tablets, Netbooks and Desktop Clients. Many of these are used to make secure transactions like Banking. It is also used as a Security Device for Web Applications and Website Memberships.

The secure transaction process has improved. I know there is encryption and also the NIC number of Ethernet cards etc. I have some thought, i think i will note it here. In one sentence "Make Every CPU Chip Unique with a Unerasable ROM ID Code or Signature" this can also be tied to a QR Code. A Firmware query spawned by a SSL TCP/IP action will return the CHIP ID which enables secure communication and device tracking overriding all user controls.

Online Security in Embedded Systems

Processor manufactures and Chip IP makers are standardized. The Secure CPU makers should obtain a license for secure CPU, which will be a CPU but with a Secure Transaction Chip with Unique Identification Code engraved within. Each Chip is unique and a replacement of CPU needs new authentication for all transactions. No two chips are made the same, the unique numbers are not on flash (like BIOS), but digitally etched-burnt with indelible e-ink. So when a person makes transaction his computer is more securely authorized. More security options like GPS in CPU for big transactions, these computers will be expensive too.

PC User Interface and Wireless Power

Wireless Charging is a Reality today, it was first conceived by me in the 90s. The first page published related to that in my netscape site.

This was conceived to get rid of cables for data and power on my desktop. I felt if we use Optics for Data and Wireless Ferrite Contact Plates to transfer power, there would be no wires at all on the desk. I even experimented with RS232 Serial Port and Ferrite Slices below thin Acrylic Plastic Sheet, it worked.

I did not patent any of my concepts, but it is offered to all humanity as an Open Design, like all my other work.

Here is a planar transformer which has PCB tracks for winding. This show that there is more scope of innovation in such ferrite transformers for short range wireless power.

PC User Interface and Wireless Power

Objects kept on a electromagnetic table must be able to draw energy from that. A Notebook or tablet can be just placed on this table to get charged.

The optic ball-less mouse is a great step in mice-tech user-interface. This mouse consumes more power, for a wireless mouse a capacitive sensor matrix based sensing may be better.

Touch Screen on PC is not common place. A combination of Touch screen and Mouse is excellent for all age-groups. Large monitors can have at least two inches of touch screen area at bottom.

Laptops, LCD Monitors make UPS (Uninterrupted Power Supply) last longer and it reduces electricity costs.

 Wireless Power for Wireless Peripherals

Wireless Mouse with capacitive sensors may consume less power, no batteries works on a Supercap, Connector-less ferrite dock for recharging

Wireless mouse rechargeable battery can recharge while moving on the Mouse Pad made of Ferrite/Ceramic 1′ Sq with Power Hot Spots every 3″

Flexible Ferrite, Silicone & Ferrite based Solid emulsion. Can be made as computer table mats to charge the supercaps of peripherals.

The Energy Efficient Wireless Peripherals can just be placed on this mat to draw the power without wires. Wireless power and Wireless Data.

Usability and Ergonomics Review
Aggregated Notes from 2008-12

Usability and Ergonomics of Electronic Consumer Equipment, product risks and safety are best studied with very old and very young people.

Personal Computers, Netbooks, Portable Communicating Devices, Remote Controls are where Usability Issues abound, and can be studied/remedied.

Optical Rotary Encoders, Magnetic/Eddy/Capacitive/Hall Effect based Non-Contact Joysticks, Makes Human An analog Interface with Digital Output.

For the people who type with two fingers; A Circular Keyboard is right. A Capacitive Touch Gesture Pad can replace the Mouse. Health & Ergo.

Peek into the Future beyond 2020

First posted around 2006 in "Ideas of delabs" and enhanced later, something to ponder about.

Robotics, Mechatronics, Nanotechnology and RF-Optics will define an Advanced Environment for Man. - Automated, Efficient and Connected.

Electric + Solar Scooters, Bikes & Cars, Mini Electric Rickshaws and Bionic Horse Carriages consume & digest Organic Material to Ethanol.

Present Internet Zap is only 10% of what it is going to be. The future of the web is all encompassing and frees communication, media & info.

EE Design Library - Electronic Product Design Resource.

LED Lighting is more important than you think it is. Start Using Alternative Energy, like Wind Power and Solar, Tidal and even Magmatic.

That Bionic Horse i was talking about

That Bionic Horse i was talking about

Ultra Low power Netbooks, Laptops, Tablets and Nettop Clients. Combined with a Resource Pooling and Sharing Community Cloud with hosted Apps

delabs Technologies - Technology Blog and Product Design.

Both Consumer Computing & Enterprise Computing needs to go Green. It is not a Novelty but it is a Serious Preparatory Strategy for a Future

Yes there is life beyond 2020 on Earth but not on Mars

Coat Pocket Computer - dapj Open Design

I could find that many HandHeld Computers are Difficult to use and the User Experience is a bit like wearing Shoes two Sizes Smaller.

So i thought i make a Feedback about how small a computer could be without any Compromise from the Present PC OS or Program Base. So we can use the same things we have on the Home PC.

That lead to a Open Concept Design which is Quite Possible, I noted the Points that can give some relief from the Suffocation of small Sizes, still maintaining mobility for people used to wearing Big Coats.

This post is mirrored here as it is related to software too


Sharp Willcom W-ZERO3

I saw a Review of Sharp/Willcom W-ZERO3. Image below, the layout is good but size is a bit small. If it is 60% bigger then it could use a regular Desktop OS and Programs (muntzed). As HDD, CPU and Batteries has become smaller, efficient and Better. I think this is close to the ideal handheld.

Handhelds - Open Source OS Handheld Devices

An Early website HandHelds.org that was active in the days before the wave of Portable Devices you see today. 2003-2004. Advanced Portable devices are now in everybody's hand.

"At the hardware level, we embrace any device that can reasonably be considered a handheld computer. We are product and architecture neutral. Software development on an open-ended set of handheld computers is welcome within the context of our group and our website. These projects include both individual efforts and work sponsored and organized by individuals, groups or companies. "

Handhelds - Open Source OS Handheld Devices

"At the operating system level, our focus is on "Unix-like" systems, including Linux and the various flavors of BSD Unix (FreeBSD, NetBSD, OpenBSD, etc.). Among these alternative operating systems, healthy and energetic competition results in better software for everyone."



My Notes -

I feel HandHeld Computers range from Advanced Calculators to Laptops, The have to be driven by batteries, charged by Mains, Solar, Wind Power or Dynamos. They can be carried around by a single human being or may be part of a Vehicle he uses. It can have a Wireless Web Connectivity or may just be a passive multimedia or games player.
