Smartwatches, with a few tweaks, can detect a surprising number of things your hands are doing like helping your spouse with washing dishes, chopping vegetables or petting a dog, say researchers from Carnegie Mellon University.
By making a few changes to the smartwatch’s operating system, they were able to use its accelerometer to recognise hand motions and, in some cases, bio-acoustic sounds associated with 25 different hand activities at around 95 percent accuracy.
Those 25 activities (including typing on a keyboard, washing dishes, petting a dog, pouring from a pitcher or cutting with scissors) are just the beginning of what might be possible to detect, the researchers said.
“We envision smartwatches as a unique beachhead on the body for capturing rich, everyday activities,” said Chris Harrison, Assistant Professor in Human-Computer Interaction Institute (HCII) at Carnegie.
“A wide variety of apps could be made smarter and more context-sensitive if our devices knew the activity of our bodies and hands,” he added.
Just as smartphones now can block text messages while a user is driving, future devices that sense hand activity might learn not to interrupt someone while they are doing certain work with their hands.
Sensing hand activity also lends itself to health-related apps — monitoring activities such as brushing teeth, washing hands or smoking a cigarette.
“Hand-sensing also might be used by apps that provide feedback to users who are learning a new skill, such as playing a musical instrument, or undergoing physical rehabilitation,” the study noted.
Apps might alert users to typing habits that could lead to repetitive strain injury (RSI), or assess the onset of motor impairments such as those associated with Parkinson’s disease.
To reach this conclusion, Harrison and his team began their exploration of hand activity detection by recruiting 50 people to wear specially programmed smartwatches for almost 1,000 hours while going about their daily activities.
More than 80 hand activities were labeled in this way, providing a unique dataset.
For now, users must wear the smartwatch on their active arm, rather than the passive (non-dominant) arm where people typically wear wristwatches, for the system to work.
Future experiments will explore what events can be detected using the passive arm.

The other factor is that the traditional players are very strong in the consumer laptop market. Top 3 players control more than 70 per cent of the market and strong portfolio, distribution, and channel reach as well as brand marketing has helped them massively. "New brands can surely make a dent in the consumer laptop market but are challenged by supply issues right now. Watch out for them in 2022 as and when supply situation eases up," Navkendar Singh, Research Director, Client Devices & IPDS, IDC India told IANS.
Dominated by HP Inc, Lenovo and Dell, the traditional PC market (inclusive of desktops, notebooks, and workstations) in India continued to be robust as the shipments grew by 50.5 per cent year-over-year (YoY) in the second quarter (Q2), according to IDC. Notebook PCs continue to hold more than three-fourth share in the overall category and grew 49.9 per cent YoY in 2Q21, reporting a fourth consecutive quarter with over 2 million units. Desktops also indicated a recovery as shipments grew 52.3 per cent YoY after recording the lowest shipments of the decade in 2Q20.
According to Prabhu Ram, Head, Industry Intelligence Group, CMR, driven by the pandemic and the associated accelerated pivot to remote work, learn and unwind culture, PCs have been witnessing heightened demand. "Despite the current supply chain constraints, PCs are here to stay in the new never normal. In the run-up to the festive season, established PC market leaders will continue to leverage their brand salience and gain market share," Ram told IANS.
HP maintained its lead in the India PC market with a 33.6 per cent share as its shipments grew 54.2 per cent annually. Dell Technologies continued to hold the second position with a 22.1 per cent share and an impressive 86.1 per cent YoY growth in 2Q21. Lenovo maintained the third position with a share of 17.8 per cent in 2Q21.
Arvind Suraj, Research Fellow, Jawaharlal Nehru University (JNU), said that there is always a trust issue with new brands. "You won't buy a laptop in 6 or 7 months just like smartphones. In this case, we often go for existing players. Brands like Lenovo, HP, ASUS and Acer have already gained our trust," he said. (IANS/ MBI)

Antipsychotics have proven to increase death rates in those with dementia, along with other poor outcomes, and so mirtazapine has been routinely prescribed. This study was designed to add to the evidence base around its effectiveness. The study recruited 204 people with probable or possible Alzheimer's disease from 20 sites around the UK, allocating half to mirtazapine and half to placebo.
The trial was double-blind; meaning that neither the researcher nor the study participants knew what they were taking. The results showed that there was no less agitation after 12 weeks in the mirtazapine group than in the control group. There were also more deaths in the mirtazapine group (seven) by week 16 than in the control group (only one), with analysis suggesting this was of marginal statistical significance.
"Dementia affects 46 million people worldwide -- a figure set to double over the next 20 years. Poor life quality is driven by problems like agitation and we need to find ways to help those affected," said lead researcher Professor Sube Banerjee, Executive Dean of the Faculty of Health at the varsity. "This study shows that a common way of managing symptoms is not helpful -- and could even be detrimental. It's really important that these results are taken into account and mirtazapine is no longer used to treat agitation in people with dementia," Banerjee added. (IANS/ MBI)
