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.

Has Hollywood finally decided to fight “Reel Life Racism”

Back in the 1960s, when the Civil Rights Movement was slowly gaining momentum in the United States, broadcasting services were employed to gather support for the movement. Images of various kinds of atrocities and violence being rendered to nonviolent Black demonstrators were broadcasted into American houses to raise awareness about the movement.

However, the response of Hollywood so far can be explained in a single word- tragic! Hollywood as a major media and content producer has massively shaped the American culture. However it has not much to show as a positive influence on race issues.

A classic 1940’s musical movie, Holiday Inn had the famous song in which White stars performed in blackface. In a 1980s hit, “Indiana Jones and the Temple of Doom” the Indians are depicted as barbaric and uncivilised. The list of such racial stereotypes is huge to be reproduced here.

Legendary Hollywood actor John Wayne made highly offensive comments in a playboy interview. His exact words are, “I believe in white supremacy until the Blacks are educated to a point of responsibility. I don't believe in giving authority and positions of leadership and judgment to irresponsible people.” He further goes on to make a series of comments, that ideally should not be coming from someone with so much influence in Hollywood.

Many legendary actors and industry icons too have struggled due to racism in Hollywood. Bruce Lee is a fine example of a person who fought against racism in the industry and refused to be cast in many roles that portrayed Chinese people in a negative light. He ultimately moved back to Hong Kong, partly due to the lack of appropriate roles. Actress Lucy Liu has also spoken about how she was too naïve to understand back in the early days as to why her friend would get multiple auditions every day, while she managed two or three in a month.

In 2015, there was a massive uproar regarding the Oscar winners after the academy awarded all 20 nominations to white actors. It quickly gained momentum with the hashtag #OscarsSoWhite becoming a global trend. Before #OscarsSoWhite, no one would have bothered to notice that 86% of top films predominantly featured white actors.

As per a Washington Post survey, film directors who ranked as the most influential decision-makers at Hollywood were predominantly whites. Hollywood might stress for newer reforms against racism on the big screen but that is not the reality at all. To put things into perspective, the Hollywood academy has never revealed information about the diversity of its members involved in the branches of the academy, such as writers, directors, etc.

The response of Hollywood movers and shakers was always akin to a tokenism, a call to push for producing more content involving black writers, producers, and actors.

George Floyd’s death was just the trigger it needed to burst out in the open the pent up anger over the centuries of discrimination, oppression, and systematic injustice meted out to black people. The way black people are portrayed in reel life directly impacts society’s attitude towards them in real life.

People started demanding that Hollywood production companies and studios should involve the people from the community in the decision-making process when the movie plot is based considerably on the members of those communities. They have also demanded that older movies depicting racially insensitive narratives should be taken out of circulation.

Disney, one of the most reputed names in Hollywood, chose to remove the movie “Song of the South” from US distribution, when the criticism for the movie grew, even though it remains available for those who know where to look. They have also announced the plan to revamp the famous Splash Mountain ride at Disneyland and Disney World to include the character of Princess Tiana- Disney’s first African American princess from the movie The Princess and the Frog.

UK TV broadcaster Sky has added a disclaimer to approximately a dozen films stating, “This film has outdated attitudes, language and cultural depictions which may cause offence today."

HBO max recently pulled the iconic film, Gone with the wind because of its controversial depiction of black stereotypes. It returned with a four and a half minute introductory video by black scholar Jaqueline Stewart for a better understanding about racism.

Ever since the resurfacing of the playboy interview of John Wayne, students and alumni at USC have been protesting against Wayne’s exhibit at the campus. However, USC has finally decided to remove the exhibit.

All these reforms are a direct result of the audience being more and more aware of racism and prejudice. However, it is Hollywood’s turn to step up and push for bigger reforms. While it would be a challenging and bold endeavor, Hollywood’s global influence makes it imperative for the industry to undergo much-needed reforms.
