With Holi round the corner, which premium smartphone will help you capture those colourful moments?

According to New Delhi-based photographer Prashanth Vishwanathan, when it comes to clicking a perfect Holi snap, the cameras in both iPhone XS and iPhone XS Max have an upper hand among the premium smartphones in India where Apple, Samsung, Google Pixel and Huawei devices jostle for space.

“Both Apple devices have a dual 12MP camera set up, offering a wide-angle and a telephoto lens. Using the iPhone XS is incredibly simple, with a pretty basic native camera app,” Vishwanathan told IANS.

Water splash and throwing Holi colour powder are best shot on “Slo-mo” video.

“Slo-mo looks great when the phone is placed on an even surface and is stationary. This trick would also avoid the focus point from shifting,” he added.

Videos look best when the camera is stable or mounted over a tripod or in an even surface. “Use a gimbal to stabilise your videos and give that cinematic feel,” said Vishwanathan.

In case one needs to capture quick movement, the burst mode is amazing as it captures sudden movement like a lighting or colour burst.

Giving Human Touch to Alexa or Siri May Not Be A Good Idea

In fact, human-like features might create a backlash against less responsive human-like chat bots.

An Indian American researcher-led team has found that giving human touch to chat bots like Apple Siri or Amazon Alexa may actually disappoint users.

Just giving a chat bot human name or adding human-like features to its avatar might not be enough to win over a user if the device fails to maintain a conversational back-and-forth with that person, according to S. Shyam Sundar, Co-director of Media Effects Research Laboratory at Pennsylvania State University.

“People are pleasantly surprised when a chat bot with fewer human cues has higher interactivity,” said Sundar.

“But when there are high human cues, it may set up your expectations for high interactivity – and when the chat bot doesn’t deliver that – it may leave you disappointed,” he added.

The researchers, who published their findings in the journal Computers in Human Behavior, also found that just mentioning whether a human or a machine is involved — or, providing an identity cue — guides how people perceive the interaction. Pixabay

In fact, human-like features might create a backlash against less responsive human-like chat bots.

During the study, Sundar found that chat bots that had human features — such as a human avatar — but lacked interactivity, disappointed people who used it.

However, people responded better to a less-interactive chat bot that did not have human-like cues.

High interactivity is marked by swift responses that match a user’s queries and feature a threaded exchange that can be followed easily.

According to Sundar, even small changes in the dialogue, like acknowledging what the user said before providing a response, can make the chat bot seem more interactive.

Because there is an expectation that people may be leery of interacting with a machine, developers typically add human names to their chat bots — for example, Apple’s Siri — or programme a human-like avatar to appear when the chat bot responds to a user.

The researchers, who published their findings in the journal Computers in Human Behavior, also found that just mentioning whether a human or a machine is involved — or, providing an identity cue — guides how people perceive the interaction.

For the study, the researchers recruited 141 participants through Amazon Mechanical Turk, a crowd-sourced site that allows people to get paid to participate in studies.

“There’s a big push in the industry for chat bots,” said Sundar.

“They’re low-cost and easy-to-use, which makes the technology attractive to companies for use in customer service, online tutoring and even cognitive therapy — but we also know that chat bots have limitations,” he added. (IANS)
