Is 'Toilet Locator' the next killer App?

I blogged earlier that Westminster city council in London using 'SatLav' service to guide you to nearest loo. Now according to news item The Daily Telegraph, UK, The trials and tribulations of searching for the nearest public toilet have been eliminated in Japan – with the launch of mobile phone software guiding users to the nearest lavatories.

The Check A Toilet programme, created by the software company Access Co, enables mobile phone users to search for maps highlighting the nearest public lavatory to their location.

From train stations and beaches to department stores and parks, the software lists thousands of maps highlighting the location of public lavatories, including details of their facilities such as baby changing areas, according to reports in Mainichi Daily News.

Users of the mobile lavatory locator are able to upload the free software from the Check A Toilet website whose lavatory location database stretches across Japan, from Tokyo to the northern city of Sapporo.

The software reflects the continually growing importance of mobile phones in every day life in Japan, home to the largest mobile phone market in the world.

Buying groceries, paying for train tickets and reserving cinema tickets are among a string of increasingly popular uses for mobile phones, 50 million of which are sold in Japan every year.

The Check a Toilet Widget, developed in cooperation with NPO Check, who created the toilet map, is a free download available for phones running Windows Mobile or Symbian S60. Entering your location in the search window brings up a map with the local lavatories indexed by number, with successive clicks revealing whether they are equipped for baby-changing or are barrier-free.

Finding toilets is a very important activity as I am sure everyone must have had a bad day when they need to go to one but cant seem to find one. There are many different ways in which local governments and application developers worldwide are trying to solve this important proble ;)

In Beijing (China), there are electronic maps at all public places with flashing lights showing public toilets. Beijing holds the world record for most public toilets in a city. Australian government has created a National Public Toilet map that can also be easily accessed via mobiles. In New York, USA, Diaroogle is serving as a premier toilet search engine. Have2P is a 'Restroom Locator and Everyday Lifesaver' app on iPhone.

Any more you know of? Feel free to add in the comments.

The smartphones war

In the past week there has been a lot of development in the filed of smartphones. Telecomm giants especially in America are gearing up for a fight to launch the best phones in the market.

Apple, Verizon wireless, Microsoft etc are all contributing to the rumours that will shape up the Smartphone future. First came a report in USA Today that Apple was considering making a CDMA version of the iPhone for Verizon. Then, "people familiar with the matter" told BusinessWeek that Apple and Verizon were actually working on an "iPhone Lite" and a WiFi-capable media pad, whatever that may be. Then, word leaked to Wall Street Journal that Microsoft and Verizon were in talks to create a new touch screen Smartphone, codenamed "Pink," that would directly compete with the iPhone. Sounds bit confusing isn’t it?

Last year has been all about Apple and it’s iPhone. Apple made a healthy profit thus beating the recession all thanks to the iphone. There is no doubt however that Apple is not resting on it’s laurels and is already the process of designing i-Phone like products in connection with Verizon.
As far as the Microsoft possible product, I'm with Morgan Keegan analyst Tavis McCourt on what the rumours mean. Microsoft regularly develops new iterations of its Windows Mobile platform, and has promised touch screen devices running on Windows Mobile 6.5 sometime late this year. The Microsoft-Verizon talks probably relate to one of these devices. And if the leak came from Microsoft, it does indeed say lot about how much the recent iPhone talk has Microsoft worried.

Although Apple has exclusive agreement with AT&T Mobility regarding the iPhone but as long is it doesn’t violate the agreement, I assume it's free to do whatever it wishes regarding other products that take advantage of wireless services. There are also some rumours that Apple is developing a CDMA version of the iPhone together with Verizon once the carrier switches to LTE 2010 or 2011, which is when AT&T's exclusive agreement for the iPhone is set to expire. If this rumour is true then I must say Apple is all set for i-Phonesque type of LTE devices as well.
So what is true and what is rumour? My guess is that Apple may need AT&T's 3G HSPA technology for the reach it wants, but it also knows AT&T needs the iPhone to keep growing its wireless data revenues. Verizon may be happy to play along with the ruse and get into AT&T's head a little bit.

Apple, AT&T and Verizon are usually pretty tight-lipped about most announcements. Throughout all of this, Apple and AT&T have maintained that their relationship is strong and that nothing has changed. Verizon too has remained mum. Let’s hope that this idle chatter will die down soon and hence we will know more.

However all doesn’t end here when it’s rumoured as per report in Wall Street Journal that Microsoft is in discussions with Verizon Wireless to produce a touch screen multimedia phone running its Windows Mobile platform as a rival to Apple's iPhone.

The device, which is code-named "Pink," will have additional software capabilities and feature Microsoft's Windows Marketplace for Mobile, according to the Journal, which cited unnamed sources familiar with the matter. A third party is expected to actually produce the hardware for the phone.

I think it’s going to be interesting and I can see only consumers coming out as winners in this war of smartphones.

mHealth and keeping fit Apps for Blackberry

From Brian Dolan, Mobile Health news:

When Fraser Edward joined Research In Motion (the company behind BlackBerry) four years ago, the device maker had only three partners for mobile healthcare applications, Edward said during a panel session at the American Telemedicine Association in Las Vegas. Today, Edward is RIM’s business manager of market development for Health & Life Sciences, and the company has 30 healthcare applications in its recently launched BlackBerry App World store.

During his presentation, Edward showed a slide of 12 mobile health companies that are “BlackBerry Solutions Partners,” which means they are clients of RIM to take advantage of the company’s marketing channels, developer know-how and more. Here’s a rundown of the 12 companies Edward counted as Solutions Partners and the mHealth buckets he put them in:

Fitness

AllSportGPS — powered by Trimble — GPS-enabled mobile application for coaching on cycling, mountain biking, running, walking and other sports activities.

BonesInMotion – GPS-enabled app targeting those participating in outdoor activity 3 or more times a week: fitness walking, running, cycling, hiking, mountain biking, GeoCaching, and other outdoor activities.

BodyMedia – Wearable, “fashionable” body monitors that record and transmit a variety of physiological data to the BodyMedia’s website.

Healthy Lifestyle

Myca - Enables nutrition professionals connect with their clients through video consults, messaging, a personalized website, and a picture food journal.

Sensei - Makes mobile health applications for a wide variety of handsets, but most recently launched a couple of iPhone applications, including one for diabetics.

Personal Health Records

Tolven - Open source healthcare solutions developer of PHRs, clinician health records and health informatics.

CapMed - Offers PHRs for families to keep track of their own health data.




Corporate Wellness/Chronic Disease Management

t+Medical - Offers disease management and remote monitoring services that work with most mobile phones and also does some work with clinical trial management.

Medtronic - Develops medical devices and services to help people better manage chronic diseases.

Healthanywhere - Offers applications that let users monitor their health from a smartphone, PC or from a “dedicated Healthanywhere supplied platform.”

Confidant - Provides a mobile-phone based service that includes feedback, coaching and context to a patient’s chronic disease management routine, while simplifying and automating the flow of information between patients and their healthcare providers.

RIM also partners with chipmaker AMD for Corporate Wellness and Chronic Disease management.

Mobile Healthcare: EpiSurveyor saving lives

DataDyne's EpiSurveyor program, funded by the United Nations Foundation and the Vodafone Foundation, has been implementing mobile technology to track and contain disease in developing nations since 2007.

In a recent and potentially devastating polio outbreak in Kenya, EpiSurveyor's new mobile platform was used to track virus carriers and immunize affected children. The campaign targeted around 2 million Kenyan children. Mobile tech will be used exclusively for new nationwide initiatives in children's healthcare, and the World Health Organization has made EpiSurveyor the standard for data collection in sub-Saharan Africa. Screenshots and video included below.

"mHealth" is a recent term for medical and public health practice supported by mobile devices, such as mobile phones, PDAs, and other wireless devices, especially in areas where Internet access via computers is lacking. Related programs allow health officials to quickly gather and assess data regardless of location or access to more traditional resources, permitting immediate mobile response to health crises. Users can create forms, view records, and share data with others.

The EpiSurveyor program began using donated Palm Pilots to gather health data in Kenya and Zambia less than two years ago. Currently, DataDyne is migrating the program to Java-based platforms for mobile phones. Beta testing began in April 2009 with Nokia S40 series devices and will expand to support other devices in May.

There's an interesting and rather basic tutorial video for field workers here which demonstrates some of the uses of EpiSurveyor's data collection tools. Much more interesting is this video, an interview with an EpiSurveyor mobile developer in Kenya who had been working through the night to prepare a stack of phones for data collection in the field:



Datadyne founder, pediatrician and CDC epidemiologist Dr. Joel Selanikio, also recently won this year's $100,000 Lemelson-MIT Award for Sustainability for his contributions to public health and international development.

Mobile Healthcare: More on TeleHealth

There are some major developments going on in the field of Mobile/Wireless healthcare. Sometime back I happen to attend a lecture organised by IET Berkshire where Prof. Lionel Tarassenko gave an overview of what developments are going on in this area. Unfortunately I could not get hold of the presentation but there is enough info on the web about it.

Vodafone has been field-testing neurosurgical telemedicine applications using third generation (3G) technology in Germany. Scientists in Denmark have successfully used text messaging to collect diary data from asthma patients in a pilot study to determine whether increased remote support improves clinical outcomes. Previous studies using home PCs to send the same diary information proved disappointing, with users rejecting the application after a short while.

Researchers from the Norwegian Centre for Telemedicine in Tromso studied parent-child interaction using a mobile and wireless system for blood glucose monitoring, and concluded that, whether or not the health outcome is improved as a result, the peace of mind provided by such a system may make it a commercial proposition.

In Finland, Medixine has been promoting home care by integrating diagnostics and patient diaries before sending results via a PC based web-link to health professionals. The company is now offering the same functionality using hand-held mobile PCs.

Researchers in the UK have, however stolen a march. When scientists from Oxford University set out to determine whether a system based on automated transfer of data, real time analysis and immediate feedback to the patient could improve glycaemic control for young adults with type 1 diabetes, they adopted the mobile approach.

The substantive difference between their work and others cited in the literature is that, with the help of funding from the charitable Vodafone Foundation, professors Andrew Neil and Lionel Tarassenko were able to conduct randomised clinical trials.

For the first time, the use of mobile telephone technology was proved to have a significantly beneficial effect and resulted in demonstrably improved clinical outcomes.

The system involved in the trials, which has subsequently been made commercially available under the “t+ diabetes” brand, uses a glucose meter linked by Bluetooth to a GPRS-enabled mobile telephone. (GPRS allows a handset to communicate with a remote server without the user having to dial in manually.)

After the patient has taken a reading in accordance with the advice he or she has been given by a GP or practice nurse, they spend around 10 seconds adding essential diary information about diet, exercise and general health via the telephone’s keypad. The system is intuitive and easy to use.

The information, together with the reading, is sent by the handset to a central computer which responds within seconds, providing patients with personalised feedback in easy-to-read graphical format delivered to their mobile’s display.

The number crunching done by the remote computer uses sophisticated algorithms to help negate the effects of occasional rogue readings and deliver a consistently meaningful result to the patient’s mobile.

This presentation here gives the motivation for the need to have a mobile based healthcare system.

• In the UK there are 17.5 million people with a long-term condition (mainly diabetes, hypertension, asthma or Chronic Obstructive Pulmonary Disease).
• Diabetes is the fastest growing disease in the Western world as a result of poor diet and obesity.
• £5.8 billion is spent per year by the NHS on diabetes and its related complications (2002 figures).
• Asthma affects 3.7 million adults and 1.5 million children in the UK (70,000 hospital admissions for asthmain 2002).
• 80% of primary care consultations relate to long-term conditions and patients with such conditions or their complications use over 60% of hospital days.

The key to minimising long-term complications is to empower patients to take more responsibility for the management of their condition.

The economic driver is reduction in unplanned hospital admissions.

Lot of time of healthcare professionals and bed space in the hospitals are wasted for the routine procedures that can be avoided by remote monitoring of the patients

Why Mobile Phones?

• Equality of care – 90% of UK population owns a mobile phone
• Real-time feedback, with two-way information flow
• Communication with remote carer based on shared data
• Economic model based on reduction in unplanned hospital admissions makes mobile phone solution a financially viable proposition
• Interactive tool to promote self-managementRegular support from remote nurse (based on real-time data)

What kinds of problems are being looked at:

• Asthma: 3 published clinical studies, 1 recruiting for Asthma UK
• COPD: 1 trial at Bristol Royal Infirmary published in Thorax
• Diabetes Type 1: 1 RCT at OCDEM published in Diabetes Care 4 trials in progress in Dundee, Eire, Dubai and Oxford 2 studies pending with UK NHS and Singhealth in Singapore
• Diabetes Type 2: 1 published clinical study for Lloyds Pharmacy
• Cystic Fibrosis: 1 published clinical trial (data submitted to NICE)
• Cancer: 1 study at Churchill Hospital published in Annals of Oncology
• Drug Titration: 1 study at Corbeilles-Essonepresented at Alfadiem and 1 trial recruiting in Oxfordshire GP Practices
• Hypertension: 1 trial recruiting in Oxfordshire GP Practices

You can read more about the tools and applications being developed here and here.

There is also a very good and detailed study of Asthama that can be seen here. There is a diary at the end that shows how readings are entered in the phone, etc.

Simplified RRC in LTE as compared to UMTS

RRC states in LTE have been simplified. In case of UMTS there was a possibility of four states with complicated movements between them but in case of LTE, there is 'RRC Idle' and 'RRC Connected'.

Figure Source: Freescale White Paper

As in case of UMTS, in 'RRC_Idle' the main task of the RRC would be monitoring and cell/plmn selection. Everything else falls in 'RRC_Connected' state. The figure above shows RRC functions in both these states.

RRC Specs for LTE is 3GPP TS 36.331

SAE design targets

With SAE implementation in full swing around the world i thought it would be good idea to discuss some of the design targest for the SAE.

Following are the main targets for SAE design:

• High-level user and operational aspects,
• Basic capabilities,
• Multi-access and seamless mobility,
• Man–machine interface aspects,
• Performance requirements for the evolved 3GPP system,
• Security and privacy, and
• Charging aspects.

Although the SAE requirements are many and split into the subgroups above, but as seen from the above points the SAE requirements are mainly non-radio access related.

The SAE system should be able to operate with more than the LTE radio access network and there should be mobility functions allowing a mobile terminal to move between the different radio-access systems. In fact, the requirements do not limit the mobility between radio access networks, but opens up for mobility to fixed-access network. The access networks need not to be developed by 3GPP, other non-3GPP access networks should also be considered. Thus the implementation for SAE should cover classes or functions for each handovers where the functions can be called as mobility functions.

The SAE requirements also list performance as an essential requirement but do not go into the same level of details as the LTE requirements. Different traffic scenarios and usage are envisioned, for example user to user and user to group communication. Furthermore, resource efficiency is required, especially radio resource efficiency (spectrum efficiency requirement for LTE). The SAE resource efficiency requirement is not as elaborated as the LTE requirement.
Thus it is the LTE requirement that is the design requirement.

Of course, the SAE requirements address the service aspects and require that the traditional services such as voice, video, messaging, and data file exchange should be supported, and in addition multicast and broadcast services. In fact, with the requirement to support IPv4 and IPv6 connectivity, including mobility between access networks supporting different IP versions as well as communication between terminals using different versions, any service based on IP will be supported

There is quality of service requirement of SAE is SAE system should for example, provide no perceptible deterioration of audio quality of a voice call during and following handover between dissimilar circuit switched and packet-switched access networks. Furthermore, the SAE should ensure that there is no loss of data as a result of a handover between dissimilar fixed and mobile access systems. A particular important requirement for the SAE QoS concept is that the SAE QoS concept should be backwards compatible with the pre- SAE QoS concepts of 3GPP. This is to ensure smooth mobility between different 3GPP accesses (LTE, WCDMA/HSPA and GSM).

The SAE system should provide advanced security mechanisms that are equivalent to or better than 3GPP security for WCDMA/HSPA and GSM. This means that protection against threats and attacks including those present on the Internet should be part of SAE. Furthermore, the SAE system should provide information authenticity between the mobile terminal and the network, but at the same time enable lawful interception of the traffic.

The SAE system has strong requirements on user privacy. Several levels of user privacy should be provided, for example communication confidentiality, location privacy, and identity protection. Thus, SAE -based systems will hide the identity of the users from unauthorized third parties, protect the content, origin and destination of a particular communication from unauthorized parties, and protect the location of the user from unauthorized parties. Authorized parties are normally government agencies, but the user may give certain parties the right to know about the location of the mobile terminal. One example hereof is fleet management for truck dispatchers.

Several charging models, including calling party pays, flat rate, and charging based on QoS is required to be supported in SAE. Charging aspects are sometimes visible in the radio access networks, especially those charging models that are based on delivered QoS or delivered data volumes. However, most charging schemes are only looking at information available in the core network.
