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.

Black Lives Matter: Why "All Lives Matter" is a False Equivalence

The phrase “All Lives Matter”, used in response to the slogan “Black Lives Matter”, has been causing a lot of controversy. The slogan is sometimes used by “colour-blind” people, who do not see colour as a basis of any of their decisions, and when they hear “Black lives Matter”, they want to add white lives to the mix, not understanding that race causes significant differences in what people face with respect to discrimination. 

In one of the incidents, a man spray-painted ‘White Lives Matter’ on the statue of Arthur Ashe, an African American Tennis legend, who was the first black Wimbledon men’s singles champion. After the man left, some people spray-painted “Black Lives Matter” over the previous paint. The man returned in a while to wipe off that message, and when asked why he had painted “white lives matter” on the statue. According to the video, the man replied "Don't all lives matter? Why is it okay to spray paint on this statue 'black lives matter,' but not 'white lives matter'? What's the difference? They all matter. Everybody matters, right?"

However, John Hayward on Breitbart throws a different light on the use of the all lives matter slogan. It talks about several instances of how people and organizations have used the phrase, like how the local authorities in Frankton, Indiana tried to have it on the side of the police cars out of general goodwill, and did not realize that the phrase was offensive to the Black Lives Matter movement.

The phrase “All Life Matters” may have been used as a slogan for joining all hands together, and expressing the fundamental right to equality. However it is found to be misguided and offensive by many people because they feel that the phrase invalidates the specific difficulties faced by the black community. For explaining this, they draw a comparison: if there is one house burning, if the other houses call out that they want the water poured on them too, that’s just counterintuitive and ignoring the burning house. Another comparison is that at a dinner table, a child has half a portion and the other has a whole. When giving another half a portion to the child with less food, if the other child demands half a portion too, it is evident that the child with the full portion is ignoring the fact that the other one has only the half. 

The intention about the usage of the phrase “All Lives Matter” doesn’t matter; it still negatively affects the “Black Lives Matter” movement. Speaking of “All Lives Matter” in response to someone asserting that “Black Lives Matter” is walking over the struggles that black people specifically face and it is a false equivalence.
