Anthony Camu, a final year Industrial Design and Technology student at Loughborough University is making headlines with his latest creation of a handheld robotic guide dog. This will be a great help to those people with visual impairment who might find it difficult to accommodate an actual guide dog in their homes.

The robot is named after the Titan goddess of light, ‘Theia’ and is shaped like a virtual gaming controller, which enthused Anthony to create this masterpiece in the first place. Theia listens to the user’s voice to lead them to their desired locations.

If the user has to go to some address (for eg. House number 4, 56th Street, Greenville Residency), they have to say ‘Hey Theia take me to House number 4, 56th Street, Greenville Residency*’. It will then process the actual data available online, like traffic density, and program the most secure route for the user to follow, quite similar to how GPS or satellite navigation works in our cars.

All the information is then communicated to the user via a machine built inside it, called a control moment gyroscope which uses the mechanism of ‘forced feedback’. These are used in spacecraft and their main function is to help in orientation purposes of the spacecraft, or in controlling the ‘spacecraft attitude’ using electric power.

This tiny built-in gyroscope physically moves the user’s hand in the direction they are supposed to go, thus giving them a feeling of being led by an actual guide dog. “The main intention was never to replace guide dogs, but instead to provide an alternative means of giving enhanced mobility options to visually impaired people” says Anthony Camu.

According to Mr. Camu, Theia will also be helpful in confronting challenging interactions like elevators or shops. While crossing a busy street, it will tend to ‘push back’ the users, cautioning them to be more sentient about their current surroundings. Moreover, Theia is quite pocket-friendly, costing about one-tenth the price of a real guide dog.

This tool will also contribute in imparting a sense of belonging and reduce the constant mental hassle and anxiety faced by the visually impaired population of the world. Since they are unable to assess their surroundings, it limits their outdoor movement. This will help them move in the outdoors more often and reduce stress while navigating the traffic on the road.

Anthony has created and experimented with many prototypes of Theia and some work is still needed to correct a few issues before the final launch his product in the market

However, he concluded that Theia has a promising future and it requires just a little more testing and research.“I know this is a grand vision, but I hope people can see the positive effects Theia could have on the blind community” he states.

Persecution of Uighur Muslims in China and the silence of Muslim Countries

Uighur are natives of  Xinjiang province of China who are Muslims and regard themselves as culturally and ethnically close to Central Asian nations. Xinjiang province has been under the control of China since it was annexed in 1949 and many Uighurs still identify their homeland by its previous name, East Turkestan. There are around 11 million Uighurs in Xinjiang and China claims that Uighurs hold extremist views that are a threat to national security.

In 2017, the Xinjiang government passed a law prohibiting men from growing long beards and women from wearing veils and dozens of mosques were also demolished.

As per the report of UN Committee on the Elimination of Racial Descrimination, the Chinese government has detained at least one million Uighurs in the detention camps in Xinjiang, China. After denying the existence of the camps for a long time, when the photos of the camps emerged, the Chinese government called them “re-education centres'' for Uighurs though the former detainees said they were detained, interrogated and beaten because of their religion, and not “re-educated.”

In July 2019 to the U.N. Human Right Council, 22 countries, mainly European countries, responded to “disturbing reports of large scale arbitrary detentions of Uighurs” and condemned the Chinese leadership.

Four days later, 37 countries, defended China’s “remarkable achievements in the field of human rights” by protecting the country from “terrorism, separatism and religious extremism.” The list of the 37 countries also included Muslim-majority countries like Saudi Arabia, Pakistan, Egypt, Qatar etc.

At the end of October 2019, 23 countries including France, the United Kingdom, United States denounced the repression of the Uighurs at the UN Committee on Social, Humanitarian and Cultural Affairs. Nevertheless, Beijing won the support of 54 countries, who praised the Communist Party’s management of Xinjiang.

In February 2019, Saudi Arabia showed their “respect” for Xi Jinping, the Chinese leader before they signed major commercial contracts with China. Egypt wants Beijing to finance its infrastructure and hence allowed the Chinese police to interrogate Uighur exiles on its soil in 2017. Pakistan, who has talked about the mistreatment of Rohingyas, has been silent on Uighurs since the Chinese Belt and Road Initiative is going on in the country.

Even Iran, who issues occasional criticism wants support from China and hence keeps the criticism coded. “There is a lot of sympathy for the Uighurs in Turkey, but the reality is that Erdogan needs China as an ally for economic reasons and to counteract the West’s diplomatic pressure on issues like Syria,” said Rémi Castets, a political scientist.

In 2017, the Organisation of Islamic Cooperation responded very differently to the Rohingya Crisis (Myanmar’s military crackdown on the country’s Rohingyas), where countries like Saudi Arabia, Iran and Turkey defended the rights of the Muslim minority group in Myanmar and actively condemned the treatment of Rohingyas in the UN Human Rights Council in Geneva.  

The question here arises is that contrary to the sentiments of their citizens, why do Muslim states stay silent over China’s abuse of the Uighurs?

Sophie Richardson, the director of China at Human Rights Watch, has a short and simple answer — there is less solidarity for Uighur than Rohingyas or Palestinians because China has managed to win these countries’ support due to its economic might.

Only time will tell how long these countries will continue to give preference to the economic interests over the anti-China sentiments of the citizens.
